Pressure Sensor capacitive type, Micro differential pressure detection

Features: High Precision Long Life more than 10 year in normal conditions Stable performance in anti interference

The type of capacitor pressure sensor mainly made from survey diaphragm and ripple seat of valve, barrier diaphragm and force release unit .At the tradition survey’s principle is that outside world change of pressure, the transmitter output capacitor data will also move to follow that change.

the capacitor transmitter changed the traditional testing the principle, not with the change the electric capacity to be measure the accomplishment basis of change of pressure .But

embed the board of line on the sensor, Thus guarantee the stable  signal of sensor.
