Custom Sensors are “Standard” for Deeter

 

The Deeter Group, market leaders in the design, development and manufacture of electronic sensors and control systems, produces a very wide range of level sensor solutions for liquids; from simple water level switches and units designed as pure water level sensors to the very popular 20 series compact float switch and the advanced LVCS continuous liquid level sensor.

 

Between 70 to 80% of all sensors manufactured by Deeter in their UK factory are now custom designs. This is not as daunting as it might seem as with its long experience and a back catalogue of many hundreds of designs a new custom design can usually be put together from a combination of pre-designed parts and control circuits.

 

Peter Whiteaker, Managing Director of Deeter Group comments; ”More than 15 years experience of manufacturing sensors has clearly demonstrated that no matter how many standard products we design, customers will frequently want something different “. Our ability to draw on our vast experience allows us to design and deliver custom sensors very quickly with low engineering and tooling costs and in quantities that meet our customers’ needs.”

 

This depth of experience means that in most cases a totally new custom design can be created in 2-3 weeks with the only design costs the customer has to bear being that of the assembly drawing – costing in the region of £30.00 – and with no large minimum order conditions.  All mechanical parts, circuit design and PCB design is done in-house helping to ensure the quality and reliability The Deeter Group is known for.

 

 

Deeter custom sensors offer a wide range of float designs for different liquids with different specific gravities and probe materials including corrosion free food grade 316L stainless steel, PVC and polypropylene for water and acid monitoring systems. Sensing may be via reed relays or hall-effect diodes and sensor length, control head and output cable may all be customer specified.

 

To accompany their custom continuous sensors Deeter has a bespoke digital display unit designed for simple panel mounting which can accommodate an appropriate LED bar-graph display and legend.

 

Examples of custom sensor systems from Deeter include simple water level sensors, float level switches, fuel level sensor or level indicators for almost any fluid.  Installations include; agricultural vehicles, tractors and lawnmowers; rainwater harvesting; header tanks; bilge, water and fuel tanks on boats; road paving machines; nuclear submarines; breweries; aircraft fuel tanks and many more.

 

The Deeter Group product range includes level sensors, complete wireless sensing systems, industrial weighing equipment, reed and proximity switches, security switches, termination assemblies, litz and magnetic wire and solar power systems.

Deeter Group Introduces a Complete Wireless Sensor System for Industrial Measuring and Control

 

Wireless Base Station with 4-to-20mA Current Loop output

Rugged Battery Powered Wireless Level Sensor

2.4 GHz Frequency band High Power Radio Transceiver

Simple and reliable operation

UK Designed and manufactured

 

The Deeter Group, market leaders in the design, development and manufacture of electronic sensors and control systems, announces the launch of its ground breaking Wireless Sensor System for industrial measurement and control.

 

At the centre of the Deeter Wireless Sensor System is the simple-to-use Base Station designed to receive data from remote wireless devices such as the Deeter Liquid Vertical Sensor (LVCS-RF) or Wireless Sender. The base station converts remote sensor input signals into industry standard process outputs and acts as the coordinator for an IEEE 802.15.4 wireless sensor network. It operates on one of 16 radio frequency channels available in the 2.4GHz ISM band. The high power transceiver can achieve a range of greater than 1km, subject to local environmental factors. The internationally recognised IEEE 802.15.4 protocol allows several wireless sensor networks to share the same wireless spectrum without interference.

 

The Base Station provides four open-collector transistor outputs which may be used to drive external relays for pumps and alarms or Deeter’s Dual Level Controller. Continuous analogue sensor data such as liquid level is output using a 4-to-20mA current-loop driver which enables interfacing with industrial process controllers or the Deeter Group’s range of Current Loop Indicators. A serial communications channel provides full-duplex RS232 and half-duplex RS485 transceivers allowing software to be developed for linking to PCs, data-loggers, PLCs or other proprietary equipment.

 

Deeter is launching the wireless Base Station with the Liquid Vertical Continuous Sensor – Radio Frequency (LVCS-RF) wireless sensor. The LVCS-RF is designed to measure a continuous liquid level and transmit this information by radio to a Deeter Wireless Base Station at regular intervals.

 

The sensor circuit is fitted inside a Food Industry Standard 316L stainless steel stem attached to the head, with a 55mm magnetic stainless steel ball-float. Standard sensing lengths are 250mm, 500mm, 750mm and 1m. Custom lengths are available on request. The LVCS-RF is powered by a single 3.6V Lithium Thionyl Chloride battery with a life typically of 12 months, has a transmission range up to 1Km in ideal line-of-sight conditions, subject to local environmental factors, and an operating temperature range of -20 to +70ºC.

 

Deeter Electronics also offer a Multi-Channel Wireless Sensor System for more complex installations. This highly cost effective wireless monitoring solution will meet the needs of a large number of smaller industrial monitoring applications. The Multi-Channel system can display the state of up to eight analogue sensors and up to thirty two switched inputs.

 

Up to eight sensor nodes, which can be multi-input Deeter Wireless Senders or Deeter Wireless LVCS-RF Liquid Vertical Continuous Sensors, can send information to a Deeter multi-channel base station. Sensor outputs are displayed, for monitoring, on a personal computer connected via an RS485 to USB adaptor using Deeter Data Viewer Software.

 

To increase transmission range and overcome potential interference problems Deeter Electronics provide a Wireless Router and an external antenna kit. Up to four wireless routers may be incorporated into a monitoring system to provide a self-healing wireless mesh network offering maximum signal reliability.

 

The Deeter Group product range includes level sensors, industrial weighing equipment, reed and proximity switches, security switches, termination assemblies, litz and magnetic wire and solar power systems.

Press Release

New Multi-channel Wireless Sensor System for Industrial Monitoring from Deeter Electronics

 

Up to eight analogue sensors and up to thirty two switched inputs

2.4 GHz Frequency band High Power Radio Transceiver

Simple and reliable operation

 

August 2010 – Deeter Electronics announce the latest addition to their ground breaking Wireless Sensor System for industrial measurement and control. The market leading international company, specialists in the design, development and manufacture of electronic sensors and control systems, has introduced a new multi-channel Wireless Sensor System for more complex installations. The new system permits the monitoring of greater numbers of remote devices than was previously possible and can display the state of up to eight analogue sensors and up to thirty two switched inputs.

 

The Deeter Multi-channel Wireless Sensor System is connected from the Base Station to a personal computer by an RS485 to USB adaptor. On the host computer Deeter Data Viewer Software displays the outputs of up to eight analogue inputs and up to thirty two switched inputs from as many as eight sensor nodes which can be multi-input Deeter Wireless Senders or Deeter Wireless LVCS-RF Liquid Vertical Continuous Sensors.

 

The Deeter Data Viewer application runs under Windows™ and provides a means of viewing the outputs from multiple sensor nodes by interpreting the data stream from the Base Station’s serial communications port. The Data Viewer visualises the performance of the Base Station and it is the best way to utilise all the features of the Deeter Wireless Sensor System. It permits the user to view the inputs from multiple sensor nodes (Deeter Wireless Senders or LVCS-RF), change the settings in the Base Station and network, record the sensor data-stream, monitor and record network events and monitor remote sensor battery voltages.

 

Up to eight Deeter Wireless Senders can be used per Multi-Channel Base Station, each take the input from either a resistive potentiometric sensor or a 4-20mA device, and up to four switched inputs. This gives a total of up to eight analogue inputs and up to thirty two switched inputs. Deeter LVCS-RF (Liquid Vertical Continuous Sensors RF) can also be used as sensor nodes. Up to eight LVCS-RF sensors can be used per Multi-channel Wireless Base Station. A combination of Senders and LVCS-RF can be used up to the maximum of eight sensor nodes.

 

The simple-to-use Deeter Base Station receives the data from remote wireless devices and acts as the coordinator for an IEEE 802.15.4 wireless sensor network. It operates on one of 16 radio frequency channels available in the 2.4GHz ISM band. The high power transceiver can achieve a range of greater than 1km, subject to local environmental factors. The internationally recognised IEEE 802.15.4 protocol allows several wireless sensor networks to share the same wireless spectrum without interference.

 

To increase the range of the Deeter Wireless Sensor System or overcome adverse environmental conditions one or a number of Deeter Routers may be added to the wireless network. The use of multiple Deeter Routers creates a highly reliable self-healing wireless mesh network.

 

Peter Whiteaker, Managing Director of Deeter Electronics, comments;”The launch of our Wireless Sensor System has been met with great interest. It provides a highly cost effective wireless monitoring solution for a large number of smaller industrial and agricultural applications. We have now received a number of customer requests for a greater number of input channels and we are very pleased to introduce our new multi-channel system. As we design and manufacture our products in the UK we are able to offer a rapid response to our customer’s requirements.”

Deeter Wireless Sensor Network products are housed in rugged ABS enclosures with external antennas. Cable glands are provided for power input and signal outputs and they come complete with external, wall mounted, universal AC input power supplies.

Press Release

Deeter Electronics adds “Router” to Extend Range of Industrial Wireless Sensor System

 

Enables high reliability wireless mesh operation

2.4 GHz Frequency band High Power Radio Transceiver

 

July 2010Deeter Electronics, a market leading international company in the design, development and manufacture of electronic sensors and control systems, announces the introduction of a Wireless Router to increase the range and reliability of their recently launched Deeter Wireless Sensor System for industrial measurement and control.

 

The new Wireless Router may be added to a Deeter Wireless Sensor System to significantly increase the range of the wireless communication between sensors and a Base Station. Deeter Wireless Routers may also be used to improve communications reliability.

 

A basic Deeter Wireless Sensor System is comprised of a Base Station and a remote sensor node, either a general purpose Deeter Sender or self contained Liquid Vertical Continuous Sensor (LVCS-RF) probe. The maximum range between these, in ideal conditions, can exceed 1Km. However in many industrial environments the signal will be attenuated by obstructions and fading may result from multiple signal paths caused by reflections. These effects reduce the quality of the communications link and the achievable range. Adding a Deeter Wireless Router to the system extends the effective range and improves signal quality.

 

In use the Wireless Router should be positioned midway between the remote probe or sender and Base Station, possibly offset in order to avoid obstructions that might cause interference. Up to four Routers may be used in a single system with data being retransmitted a number of times before reaching the Base Station. This will greatly extend the transmission range and reliability.

 

The use of multiple Routers allows the wireless network to automatically establish the most effective signal route between probe and Base Station at turn-on. Should this signal path become interrupted for any reason the Router network will re-establish the most efficient and reliable signal path. In this mode the Routers are operating as a self-healing wireless mesh network offering maximum signal reliability.

 

The Deeter Wireless Router must be permanently powered-up to relay messages. Any message sent from a base station to a “sleeping” battery powered remote node or sensor will wait at the last Router until the sensor wakes up and polls for data.

 

The Deeter Wireless Sensor system uses the internationally recognised IEEE 802.15.4 protocol in the 2.4GHz ISM radio band allowing users to install approved devices with no licensing requirements. It operates on one of 16 radio frequency channels available allowing several wireless sensor networks to share the same wireless spectrum without interference.

 

The Deeter Wireless Router is housed in an ABS enclosure with an external antenna. Power is provided by an external 5VDC mains wall mounted adapter connected via cable glands. An optional 3m extension lead and bracket are available for mounting the antenna in a position more favourable to wireless communication should the need arise.

 

Peter Whiteaker, Managing Director of Deeter Electronics, comments; ”Our new Wireless Router is the final piece in our class leading wireless sensor system. Adding one or a number of Routers to a measurement system not only extends the communications range but can greatly improve the reliability of the transmitted data signal. We can now offer our customers a complete, simple to operate, low cost wireless sensor system which provides a very viable alternative to conventional control and instrumentation systems.”

 

The Deeter Group product range includes level sensors, industrial weighing equipment, reed and proximity switches, security switches, termination assemblies, litz and magnetic wire and solar power systems.

Press Release

Deeter Electronics “Sender” Extends Industrial Wireless Sensor System to incorporate Industry Standard Inputs

 

2.4 GHz Frequency band High Power Radio Transceiver

Simple and reliable operation

 

June 2010 – The Deeter Group; a market leading international company in the design, development and manufacture of electronic sensors and control systems, announces introduction of its Wireless Sender which increases the possible applications of the recently launched Deeter Wireless Sensor System for industrial measurement and control.

 

The new Wireless Sender is an extension to a Deeter Wireless Sensing System and communicates with a Deeter Base Station which acts as a coordinator for an IEEE 802.15.4 wireless network. The Deeter Sender has a number of sensing inputs and will transmit sensor data at regular intervals to the Base Station for conversion to process system outputs and alarms.

 

The Deeter Sender has the following sensor inputs; four discrete inputs from external switches, such as Deeter level sensors, float switches, or other voltage free contacts, one analogue resistive input, such as a Deeter Resistive LVCS (Liquid Vertical Continuous Sensor) or an industry standard 4 – 20mA current loop analogue input.

 

Wireless communication between the Deeter Sender and Base Station uses the internationally recognised IEEE 802.15.4 protocol in the 2.4GHz ISM radio band providing a range of up to 1km under ideal conditions.

 

The Sender is housed in an ABS enclosure with an external antenna and cable glands for power and signal inputs. An optional 3m extension lead and bracket are available for mounting the antenna in a position more favourable to wireless communication should the need arise. The unit can be powered by an internal 3.6V Lithium Thionyl Chloride battery or externally by a 5VDC mains powered wall adaptor. The internal battery acts as a no-break back-up should the external supply be interrupted.

 

If a 4-20mA current loop sensor input is being monitored, a small amount of power is derived from this source to help extend battery life. Battery life for a battery only powered Deeter Sender is greater than one year (based on a transmission interval of 10 seconds) transmission rates of 1 – 60 seconds are user configurable.

 

 

Information from a Deeter Sender will be received and processed by the simple-to-use Base Station designed to receive data from remote wireless devices such as the Deeter Liquid Vertical Sensor (LVCS-RF). The base station converts remote sensor input signals into industry standard process outputs. It operates on one of 16 radio frequency channels available in the 2.4GHz ISM band. The internationally recognised IEEE 802.15.4 protocol allows several wireless sensor networks to share the same wireless spectrum without interference.

 

The Base Station provides four open-collector transistor outputs which may be used to drive external relays for pumps and alarms or Deeter’s Dual Level Controller. Continuous analogue sensor data, such as liquid level, is output using a 4-to-20mA current-loop driver which enables interfacing with industrial process controllers or the Deeter Group’s range of Current Loop Indicators. A serial communications channel provides full-duplex RS232 and half-duplex RS485 transceivers allowing software to be developed for linking to PCs, data-loggers, PLCs or other proprietary equipment.

 

 

Peter Whiteaker, Managing Director of Deeter Electronics, comments; ”The introduction of our new Wireless Sender increases the flexibility of our wireless sensor system by allowing widely used conventional sensor inputs to be simply connected to our robust and easy to use wireless communication system. This not only allows existing sensors to communicate via a wireless network but also means our customers are not locked-in to using a single source for their measurement and control needs. The simplicity of installation, removal of cabling costs and increased reliability of control signals makes a Deeter Wireless Sensor System a very viable alternative to conventional control and instrumentation systems.”

Deeter Group Wireless Sensor System

Background

The Deeter Group has been providing electronic services to industry since 1982. With the formation of Deeter Electronics in 1991 the company has become a major international manufacturer and supplier of control and instrumentation systems, including electronic sensors, industrial weighing equipment, reed and proximity switches, security switches, termination assemblies and other products and services to manufacturing industry.

 

A perennial problem with installing control and measurement systems in industrial environments is cabling. Installing and maintaining the reliable operation of cable networks can be very difficult in factories and larger industrial facilities where buildings may be remote. Roads, railways and even rivers may need to be crossed creating their own sets of health and safety hazards. Cable faults can easily be caused by mechanical damage and the environment resulting in costly lost production and safety issues which could result in life hazard, damage to process equipment and unnecessary plant shut-down.

 

The recent advent of compact, high reliability short range wireless devices has allowed Deeter to develop a wireless sensor system which can transform industrial control and measuring systems. Greatly reducing the cost and time required to install, increasing convenience and reliability and enabling simple relocation of sensors should factory layout change. In addition Deeter probes are battery powered removing the additional layer of installation complexity of providing mains power in remote locations for conventional measuring instruments.

 

.A Deeter Wireless Sensor System may include a number of Wireless Routers to form a wireless ‘mesh’ network. This allows signals to be automatically re-routed around any broken links in the mesh creating a built-in self-healing capability to further ensure communications reliability.

 

The Deeter Wireless Sensor System will be welcomed by control engineers in industrial and manufacturing industries such as food and beverages, cooling systems and agriculture.

 

System Applications and Features

The Deeter Wireless Sensor System was primarily designed for use in liquid level sensing, to complement the very popular existing range of Deeter float-switches and continuous level sensors. Countless other applications for the Deeter Wireless Sensor system are possible, including:

• remote monitoring of switch inputs to drive relay outputs

• converting a potentiometer input to a 4-to-20mA current loop output

• mirroring a 4-to-20mA current loop signal

• switching relays at preset input thresholds

 

The System has the following advanced features:

• Sophisticated RF Communications and Wireless Network capability

• Fully automatic operation once the system is installed

• Battery powered remote sensors

 

RF Communications

The system uses very reliable high power RF transceiver modules and rugged external antennae to achieve the best possible wireless communication range. Range can be further extended by adding one or more Deeter Wireless Routers which receive and re-transmit the signal with increased gain. The Base Station acts as the coordinator for the wireless network and operates in the 2.4GHz ISM (Instrumentation Scientific and Medical) frequency band. This allows the system to be used world-wide without requiring a site radio operating licence. Local regulations may restrict the maximum RF transmit power and Deeter provide different variants of the Wireless System devices for the USA, Canadian and European markets to satisfy these constraints. The IEEE 802.15.4 protocol used in the Deeter Wireless Sensor System allows several networks to share the same frequency without interfering with each other. The protocol uses sophisticated techniques to ensure good communications using very low power signalling. This allows the Deeter Wireless Sender or LVCS-RF (RF Liquid Vertical Continuous Sensor) probe to operate using battery power. Once the system is installed it will operate reliably for extended periods without any further intervention. When several Routers are used they form a ‘mesh’ network, and signals can be re-routed around any broken links in the mesh. Thus, the system has a built-in self-healing capability to further ensure communications reliability.

 

Wireless Range

At maximum transmission power (USA version) the distance between sensor node and Base Station may be up to 4km in an ideal, open field installation. For operation in Europe, regulations restrict the maximum transmission power and a range of up to 1000m may be possible. However, in most practical environments the radio signal will be attenuated by obstructions and by multi-path fading caused by reflections. To improve range, a clearer signal path can often be achieved by increasing the height of the antenna and Deeter supply an antenna extension kit for this purpose. A Deeter Wireless Router placed somewhere between the remote sensor and Base Station, or off to one side of the direct line between the two, will greatly extend the wireless range and up to four Routers may be used in a single system.

 

System Devices

There are four devices currently in the Deeter Wireless Sensor product range:

• Base Station

• Wireless Sender

• LVCS-RF Liquid Vertical Continuous Sensor probe

• Wireless Router

 

A basic Wireless Sensor System comprises a Base Station and a single sensor node, either a Sender or LVCS-RF. A Router may be added to the system to improve communications reliability or to extend the wireless range. Up to four Routers may be used in a single system.

The sensor nodes can accept a range of input devices to suit the application:

• Four switch inputs (Sender only)

• An analogue resistive input (Sender and LVCS-RF)

• A 4-to-20mA current-loop sensing input (Sender only)

 

The Base Station has a range of outputs to drive a wide variety of possible

devices:

• Four open-collector transistors for relay operation etc.

• 4-to-20mA current loop driver

• Serial communications output via RS232, RS485 or USB

(At present, serial communications is reserved for diagnostic data. Future

developments are expected to include data-logging features.)

 

The complete Deeter Group product range includes level sensors, industrial weighing equipment, reed and proximity switches, security switches, termination assemblies, litz and magnetic wire and solar power systems.

Wireless Site Survey Tool

Wireless Site Survey Tool

When considering implementing a wireless sensor network or looking to extend an existing installation, one of the major concerns is getting the data to the required destination. Every site has a unique radio profile with signal strength being affected by a number of different factors. The Deeter Wireless Site Survey Tool will analyse that unique radio profile and identify if there are any problems with wireless propagation.

Easy to use, it allows users to test the radio link quality (LQI) and data transmission status at the desired sensor locations prior to installation. It will also determine if routers are needed and where they should be located to ensure signal integrity.

The WSST consists of a transceiver (Base Station) and transmitter (Sender) and is designed to be a vendor independent. It can be used to survey any site looking to implement or extend a wireless network with transmitters using any IEEE 802.15.4™ based protocol in the 2.4GHz ISM frequency band. In addition it can also be used to check Wi-Fi signal propagation.

• Simple to use
• Ideal for point to point and sensor network applications
• User configurable
• Base Station displays LQI and data packet information in real time
• Auto or fixed channel operation
• Range 1000 metres in ideal conditions (4000 metres in the US)
• Transmit power output selectable
• No software required
• Sender can also be used as a router

If you require more information on conducting a survey or would like more information on our Free Survey Service please call Deeter Sales 44(0)1494 566046 or email [email protected].

All Sensors can be Wireless

A perennial problem with installing control and measurement systems in industrial environments is cabling. Installing and maintaining the reliable operation of cable networks can be very difficult in factories and larger industrial facilities where buildings may be remote. Roads, railways and even rivers may need to be crossed creating their own sets of health and safety hazards. Cable faults can easily be caused by mechanical damage and the environment resulting in costly lost production and safety issues which could result in life hazard, damage to process equipment and unnecessary plant shut-down.

The recent advent of compact, high reliability short range wireless devices has allowed Deeter to develop a wireless sensor system which can transform industrial control and measuring systems. Greatly reducing the cost and time required to install, increasing convenience and reliability and enabling simple relocation of sensors should factory layout change. In addition Deeter probes are battery powered removing the additional layer of installation complexity of providing mains power in remote locations for conventional measuring instruments.

.A Deeter Wireless Sensor System may include a number of Wireless Routers to form a wireless ‘mesh’ network. This allows signals to be automatically re-routed around any broken links in the mesh creating a built-in self-healing capability to further ensure communications reliability.

The Deeter Wireless Sensor System will be welcomed by control engineers in industrial and manufacturing industries such as food and beverages, cooling systems and agriculture.

System Applications and Features
The Deeter Wireless Sensor System was primarily designed for use in liquid level sensing, to complement the very popular existing range of Deeter float-switches and continuous level sensors. Countless other applications for the Deeter Wireless Sensor system are possible, including:
• remote monitoring of switch inputs to drive relay outputs
• converting a potentiometer input to a 4-to-20mA current loop output
• mirroring a 4-to-20mA current loop signal
• switching relays at preset input thresholds

The System has the following advanced features:
• Sophisticated RF Communications and Wireless Network capability
• Fully automatic operation once the system is installed
• Battery powered remote sensors

RF Communications
The system uses very reliable high power RF transceiver modules and rugged external antennae to achieve the best possible wireless communication range. Range can be further extended by adding one or more Deeter Wireless Routers which receive and re-transmit the signal with increased gain. The Base Station acts as the coordinator for the wireless network and operates in the 2.4GHz ISM (Instrumentation Scientific and Medical) frequency band. This allows the system to be used world-wide without requiring a site radio operating licence. Local regulations may restrict the maximum RF transmit power and Deeter provide different variants of the Wireless System devices for the USA, Canadian and European markets to satisfy these constraints. The IEEE 802.15.4 protocol used in the Deeter Wireless Sensor System allows several networks to share the same frequency without interfering with each other. The protocol uses sophisticated techniques to ensure good communications using very low power signalling. This allows the Deeter Wireless Sender or LVCS-RF (RF Liquid Vertical Continuous Sensor) probe to operate using battery power. Once the system is installed it will operate reliably for extended periods without any further intervention. When several Routers are used they form a ‘mesh’ network, and signals can be re-routed around any broken links in the mesh. Thus, the system has a built-in self-healing capability to further ensure communications reliability.

Wireless Range
At maximum transmission power (USA version) the distance between sensor node and Base Station may be up to 4km in an ideal, open field installation. For operation in Europe, regulations restrict the maximum transmission power and a range of up to 1000m may be possible. However, in most practical environments the radio signal will be attenuated by obstructions and by multi-path fading caused by reflections. To improve range, a clearer signal path can often be achieved by increasing the height of the antenna and Deeter supply an antenna extension kit for this purpose. A Deeter Wireless Router placed somewhere between the remote sensor and Base Station, or off to one side of the direct line between the two, will greatly extend the wireless range and up to four Routers may be used in a single system.

System Devices
There are four devices currently in the Deeter Wireless Sensor product range:
• Base Station
• Wireless Sender
• LVCS-RF Liquid Vertical Continuous Sensor probe
• Wireless Router

A basic Wireless Sensor System comprises a Base Station and a single sensor node, either a Sender or LVCS-RF. A Router may be added to the system to improve communications reliability or to extend the wireless range. Up to four Routers may be used in a single system.
The sensor nodes can accept a range of input devices to suit the application:
• Four switch inputs (Sender only)
• An analogue resistive input (Sender and LVCS-RF)
• A 4-to-20mA current-loop sensing input (Sender only)

The Base Station has a range of outputs to drive a wide variety of possible
devices:
• Four open-collector transistors for relay operation etc.
• 4-to-20mA current loop driver
• Serial communications output via RS232, RS485 or USB
(At present, serial communications is reserved for diagnostic data. Future
developments are expected to include data-logging features.)
