ABSTRACT:
A pressure transducer is arranged to mount a semiconductor pressure sensor in a housing such that the pressure of a high-pressure fluid is applied to one side of the semiconductor pressure sensor through a high pressure seal diaphragm and a sealed liquid in the high pressure side, while the pressure of a low-pressure fluid is applied to the other side of the sensor through a low-pressure seal diaphragm and a sealed liquid in the low pressure side, and a protecting member is provided closer to the low-pressure seal diaphragm.
