PN52C series pressure (liquid level) transmitter uses capacitive pressure core for operation
The isolating diaphragm and filling fluid at the high and low pressure sides transmit the process pressure to the filling
Then fill the liquid to transfer the pressure to the sensing diaphragm in the center of the sensor. pass
The sensing diaphragm is a tensioned elastic element, and its displacement changes with the pressure (for
For gauge pressure transmitters, atmospheric pressure is applied as if it were on the low pressure side of the sensing diaphragm).
For absolute pressure transmitter, the low pressure side always maintains a reference pressure. Of sensing diaphragm
The large displacement is 0.1mm, and the displacement is proportional to the pressure.
