Kistler Model 7261 Low Pressure Quartz Transducer

Kistler,Model,7261,Low,Pressure,Quartz,Transducer Low pressure quartz transducer for dynamic and short term static pressure measurements from vacuum to 10 bar. High resonant frequency, flush welded diaphragm.

The measured pressure acts through the diaphragm on the quartz crystal measuring element which transforms the pressure into an electrostatic charge. The stainless steel diaphragm is welded flush and hermetically to the stainless steel transducer 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 screw-on cover and the hose nipple simplify in many cases the connection to the measured pressure.

The low pressure quartz transducer 7261 is suited for fast dynamic pressure measurements if used without cover. In case both cover and nipple are mounted, the frequency response is reduced considerably due to the Helmholtz resonator effect. Quasistatic measurements of several minutes duration are possible under appropriate conditions.
