The results of the pressure pulsations measurements connected with the process of the vapor films explosive destruction near heated bodies were analyzed. It was stated that under such conditions false pressure pulses are generated. It was experimentally shown and approved by numerical calculations that such interference may be caused by pressure pulsations due to thermal interaction of the piezotransducers used in the experiments with the high-temperature fragments of vapor. The mechanism of the false pressure pulses generation process caused by the thermal deformation of the membrane that affects the pressure sensor (piezoelectric crystal) was described.
