Kistler Model 7001 Polystable Quartz High Temperature Pressure Sensor
Kistler Model 7001 Polystable Quartz High Temperature Pressure Sensor for measuring dynamic and quasistatic pressures up to 250 bar at temperatures up to 350°C.
The measured pressure acts through the diaphragm on the quartz crystal measuring element, which transforms the pressure p (bar) into an electrostatic charge Q (pC = picoCoulomb). 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 tight and has a ceramic insulator. The Polystable quartz allows an operating temperature of up to 350°C.
The quartz pressure sensor Type 7001 is especially suited for dynamic pressure measurements on objects offering little mounting space. It must be used, instead of Type 701A, where the temperature of the mounting location reaches up to 350°C.
Typical applications include pressure measurements on combustion engines, compressors, pneumatic and hydraulic installations (except injection pumps).
