とする差圧・圧力発信器。 Both pressures are measured through a pair of pressure measuring ends equipped with diaphragms that receive different pressures to be measured, and a pressure transmission medium sealed in the respective sealed spaces partitioned by the diaphragms on each pressure measuring end side. A pressure detection means for detecting a pressure difference at the ends is provided, and a portion of the one pressure-measuring end near the diaphragm fixing part communicates with an enclosed space partitioned by the diaphragm on the other pressure-measuring end. A differential pressure/pressure transmitter characterized in that a temperature compensation space is provided in which a pressure transmission medium is enclosed.
