Complete dynamic pressure measurement chains in virtually any aerospace environment
To offer you a high performance in extreme environments, our dynamic pressure sensors incorporate our core piezoelectric technology. The varying pressure applied on the sensor’s membrane applies force on the piezoelectric sensing element, which in turn generates electrical charges proportional to the pressure pulsation.
Our gas turbine dynamic pressure sensors are used over a wide dynamic range and can incorporate active acceleration compensation to improve signal to noise ratio.
The electrical charges generated by the sensing element need to be converted into a voltage or current output for further processing. Depending on the application, this is performed either directly inside the sensor (integrated electronics piezoelectric – IEPE standard) or further away on the measurement chain (for high temperature locations). In that case, the use of a special high temperature mineral insulated cable and/or lower temperature “low noise” cable to reliably convey the electrical charges up to a remote charge converter is necessary.
