Quartz pressure sensor for measuring dynamic and quasistatic pressures up to 250 bar at temperatures up to 200°C. The built-in accelerometer compensates interference signals produced by shock or vibration in the direction of the sensor axis.

The measured pressure acts through the diaphragm on the quartz crystal measuring element, which transforms the pressure p (bar) into an electric charge Q (pC = pico-Coulomb). The stainless steel diaphragm is welded flush and hermetically to the stainless steel sensor housing. The signal produced by acceleration (shock or vibration) due to the sensor mass, is compensated by a signal of inverse polarity yielded b y the built-in accelerometer. The connector is welded to the body, but its Teflon insulator is not absolutely tight.

The quartz pressure sensor Type 7031 is suited for dynamic pressure measurements on heaving vibrating objects. This sensor is about 10 times less sensitive to vibrations than the standard Type 601A. For very high frequencies or reduced mounting space, the sensor 6031 is used.
