る差圧伝送器。[Claims for Utility Model Registration] The differential pressure detector 23 detects the measurement pressure acting on the diaphragm 29 on the low pressure side and the diaphragm 30 on the high pressure side through the first sealed liquid 32 and the second sealed liquid 33. In the differential pressure transmitter, information on the differential pressure of the measured pressure is obtained from a change in capacitance caused by the differential pressure of the measuring diaphragm. A differential pressure transmitter characterized in that the differential pressure transmitter is disposed in a filled chamber 21a, and one of the measurement pressures is applied to the chamber 21a via the first sealed liquid 32 or the second sealed liquid 33. .
