Kistler Models 601A, 601H Quartz High Pressure Sensor
Quartz pressure sensor for measuring
dynamic and quasistatic pressures up to 1000 bar at temperatures up to 200°C. Very small dimensions, high natural frequency.
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 = 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 miniature quartz pressure sensors of the 601 Series are especially suited for dynamic pressure measurements on objects offering little mounting space. If mounting space and max. measured frequency allows for, the sensor Type 701A should be selected because of its five times high sensitivity.
Typical Applications: Pressure measurements on combustion engines, compressors, pneumatic and hydraulic installations (except injection pumps). Measurements of explosion and blast pressures (601H).
