Pressure Transducers
Dynamic Pressure Transducer
for high temperature
applications.

Vibro-Meter has developed piezoelectric dynamic pressure sensors for many aviation applications for extreme temperature environments. The force created on the diaphragm is applied to the piezoelectric stack which produces an electric signal charges). The secondary effect of vibration is internally compensated. Thus the generated signal is purely proportional to the dynamic pressure applied to the diaphragm. The working temperatures of these transducers can be higher than 700ºC. These types of transducers are used mainly for jet pipe resonance detection on various engines for military applications. State of the art devices have also been released with two channels in order that redundancy is "built in" and a better interface provided for BITE functions.
