Overview
The SITRANS LH100 Pressure Transmitter is a submersible sensor for measurement of hydrostatic level. It converts level-proportional hydrostatic pressure into a standardized signal.
The LH100 measures liquid levels in tanks, containers, channels and dams, and is temperature-compensated for use in a wide range of temperatures.
It features a compact design, as well as a built-in ceramic sensor which is equipped with a Wheatstone resistance bridge, and an electronic circuit fitted in a stainless-steel housing. Additional to this there is a connecting cable which contains a vent pipe to prevent condensation build-up.
Additional available accessories:
- Junction box
- Cable hanger
