PRESSURE PULSE GENERATING SYSTEM FOR DYNAMIC CALIBRATION OF SILICON LOW RANGE PRESSURE SENSORS

− The dynamic calibration of silicon pressure sensor and whole pneumatic part of the pressure transducers becomes an important problem in many applications. The known methods are not satisfactory for low range sensors. In this paper a simple system for short pulse pressure generation is described. A method for determination of frequency response based on pressure pulse signal is presented. The obtained results show that this method is simply for realisation and useful for low range silicon pressure sensors.
