Kistler Model 701A Quartz Pressure Sensor
|
The measured pressure acts through the diaphragm on a quartz crystal measuring element, which transforms to pressure p (bar) into an electrostatic charge Q (pC = pico-Coulomb). The stainless steel diaphragm is welded flush and hermetically to the stainless steel sensor body. The quartz elements are mounted in a highly sensitive arrangement (transversal effect) in the quartz chamber, which is welded hermetically to the body. The connector is welded to the body, but its Teflon insulator is not absolutely tight. The quartz pressure sensor 701A is suited for dynamic pressure measurements. For very high frequencies or reduced mounting space for sensor 601 is used. Typical applications include pressure measurements on combustion engines, compressors, pneumatic and hydraulic installations (except injection pumps). |
Kistler Model 701A Quartz Pressure Sensor for measuring dynamic and quasistatic pressures up to 250 bar at temperatures up to 200°C.
