3 Description
3.1

Application range

The LH300 pressure transmitter is a submersible sensor for hydrostatic level measurement. The pressure transmitter
measures the liquid levels in tanks, containers, channels and dams.
The pressure transmitter is available for various measuring ranges and optionally with explosion protection. A cable box and
an anchor clamp are available as accessories to make installation easier.
The pressure transmitter is used, for example, in the following industrial areas:
● Water supply
● For use in pressureless/open tanks and wells
3.2 Structure
The pressure transmitter has a built-in ceramic sensor which is equipped with a Wheatstone resistance bridge.
The pressure transmitter is equipped with electronics that is installed, together with the sensor, in a stainless steel
enclosure. There is also a vent pipe in the connecting cable.
The measuring diaphragm is effectively protected against external influences by a protective cover.
The sensor, the electronics and the connecting cable are housed in an enclosure with small dimensions.
The pressure transmitter is suitable for a wide temperature range.
