Thermal shock of instantaneous temperature on piezoelectric pressure transducer is introduced
tight force
nature frequency and sensitivity of transducer can be changed
instantaneous temperature error is formed.The special film structure of transducer can reduce greatly the instantaneous temperature error from the thermal shock.Through the experimentation research on the thermal shock of two piezoelectric pressure transducers
inference of the thermal shock on the transducer is expounded.Measured data and analyzable results are presented.
