Kistler Model 6031 Quartz Pressure Sensor, Acceleration-Compensated
Very small quartz pressure sensor for
measuring dynamic and quasistatic pressures up to 250 bar at temperatures up to 200°C. High natural frequency. 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 charges 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
by the built-in accelerometer. The connector is welded
to the body, but its Teflon insulator is not absolutely
tight.
The miniature quartz pressure sensor Type 6031 is especially suited for dynamic
pressure measurements on heavy vibrating objects. This sensor is about 10 times less sensitive to vibrations than the
standard Type 601A
Special version: This sensor is also available with a
diaphragm optimized against thermo shocks (Type 6031U18).
It can be used for measuring the cylinder pressure in
racing engines at very high rpm.
