Product Description

Metal capacitance differential pressure sensor dp sensor cell used for pressure transmitter

Product Description

Product description:                                                                                                

The medium pressure is transferred to the test diaphragm in the middle of δ room by the barrier diaphragm and Silicon oil,as the test diaphragm is tight flexible element, it produce displacement following the pressure differential. The displacement of the diaphragm and pressure differentialare in direction proportion, the max displacement is 0.1mm, It is tested by the by the capacitiveplat on the both side, Then the differential 
capacitor between the test diaphragm and capacitive board switched to standard output by the Circuit Current.
