High Accuracy diaphragm metal capacitive differential pressure sensor with low cost
Product description:
The medium pressure is transferred to the test diaphragm in the middle of δ room by the barrier diaph
ragm 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 differential are in direction proportion, the max disp
lacement is 0.1mm, It is tested by the by the capacitiveplat on the both side, Then the differential cap
acitor between the test diaphragm and capacitive board switched to standard output by the Circuit Cu
rrent.
