The LVCS HE is a liquid level sensor featuring a float that can move vertically along a stem. Hall-effect sensors in the stem detect small step-changes in level and, particularly over longer lengths, the output approximates to a continuous analogue signal.
The standard analogue output circuit is a loop-powered 4-20mA driver. A multi-interface driver is also available on request and features the following:
- 4-20mA output
- 0-10V output
- 2x open-collector transistor outputs
- Serial communications port
The standard LVCS HE is designed to fit a 21mm hole in the top of a tank, secured by an aluminium head, and has a ½ inch BSP thread. Sensing resolution is 15mm with measuring lengths of 1.25m, 1.5m, 1.75m and 2m.
All fittings inside the tank are made from stainless steel 316L and are welded to make a tough and durable sensor. The LVCS HE is therefore ideally suited for use in food and petrochemical applications, and for use in harsh environments. It also has an IP rating of IP67.
Custom lengths can be made to order and heads with different threads or pressure tank fittings are available. Deeter also make the LVCS HE in other materials, for further details Contact Us or call our sales office to discuss your requirements.
|LVCS HE 5: Measured length L = 1250mmLVCS HE 6: Measured length L = 1500mmLVCS HE 7: Measured length L = 1750mm
LVCS HE 8: Measured length L = 2000mm
Note: The overall length is 90mm longer than the measuring length. Please check you have enough clearance in the tank.
