Rugged Battery Powered Wireless Level Sensor

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

2.4 GHz Frequency band High Power Radio Transceiver

Simple and reliable operation

  

May 2010The Deeter Group; a market leading international company 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). The base station converts remote sensor input signals into industry standard process outputs. The Base Station 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.

 

The Base Station has three internal push-button switches and a 2-line by 16-character LCD. The buttons are accessible with the lid removed and are used in conjunction with the display to select installation options during initial setup. Once the system has been installed it will continue to operate without any further need for user intervention. The Base Station is housed in a rugged ABS enclosure with an external antenna. It has cable glands for power input and signal outputs and is supplied with an external, wall mounted, universal AC input power supply.

 

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 device is battery powered and transmits wireless sensor data using the IEEE802.15.4 protocol operating in the 2.4GHz frequency band. The  transmission range is up to 1Km in ideal line-of-sight conditions. The operating temperature range is -20 to +70ºC.

 

The LVCS-RF circuitry is housed in an IP65 rated die-cast Aluminium head with an external antenna. 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 sensor circuit is fitted inside a Food Industry Standard 316L stainless steel tube attached to the head, with a 55mm magnetic ball-float. Standard sensing lengths are 250mm, 500mm, 750mm and 1m. Custom lengths and materials are available on request. The LVCS-RF is powered by a single 3.6V Lithium Thionyl Chloride battery with a life typically of 9 months (based on a transmission interval of 10 seconds and an uninterrupted wireless link to the base station).

 

Peter Whiteaker, Managing Director of The Deeter Group, comments;”Over the past 20 years the Deeter Group has justly earned its reputation as a supplier of quality products and services. The introduction of our new British designed and manufactured wireless sensor systems takes us into a new and growing market sector. Our wireless base station and LVCS-RF sensors can be integrated into our customers systems or we can provide a complete measurement package by simply adding a Deeter Current Loop Indicator”

 The Deeter Electroncs Inc. market leaders in the design, development and manufacture of electronic sensors and control systems, has added a Wireless Modbus Gateway to its range of Wireless Sensor Network products.

Any users of Modbus communication protocols will find the new Deeter Wireless Modbus Gateway is a simple and cost effective way to connect a Deeter Wireless Sensor network to a Modbus system to monitor physical or environmental conditions, such as liquid levels, temperature, humidity, vibration, pressure and proximity.

The Deeter Wireless Modbus Gateway communicates with the Modbus network via a RS485 port in slave mode; it coordinates the wireless sensor network and manages data acquisition from the sensors using the IEEE 802.15.4™ wireless protocol in the 2.4GHz ISM frequency band.

A Deeter Wireless Modbus Gateway may be installed as a component of a new control or measurement system or as an extension to an existing wired sensor system in order to add wireless connected sensors.

Craig Harnish, Vice President of Sales at Deeter Electronics Inc. Comments; ”Modbus has become one of the most popular standard communications protocols used in process control and is now amongst the most commonly available means of connecting industrial electronic devices. Our new Modbus Gateway will allow customers to integrate Deeter Wireless Sensor products into existing or new control systems in locations where wireless has cost, safety and convenience advantages over conventional cable connected systems.”

Deeter Wireless products may be used indoors or outside and all are rated to IP64, have an operating temperature range of -20ºC to +70ºC and compliant to FCC part 15.

The Deeter Group’s comprehensive range of wireless sensors and network components may be used to remotely monitor temperature, pressure, flow, humidity, liquid level, float or proximity switches or any sensor connected to a 4-20mA control loop. Deeter wireless sensor networks are very versatile and can range from a simple single sensor measurement to complex multi sensor and multi-vendor systems with mixed sensor inputs and routers to extend wireless range and offer self-healing mesh networks.

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].
