4. Function

LFH: Submersible pressure transmitter for level measurement
The hydrostatic pressure prevailing within the application is transformed into a standardised elec-
trical signal through the deflection of the diaphragm, which acts on the sensor element with the
power supply fed to the transmitter. This electric signal changes in proportion to the hydrostatic pres-
sure and can be evaluated correspondingly.
