Piezoelectric pressure indicator

In a piezoelectric pressure indicator comprising a casing, a pressure receiving member at the bottom of the casing, piezoelectric elements mounted on the pressure receiving member, an acceleration compensating weight and acceleration compensating piezoelectric elements, both piezoelectric elements being connected such that the voltage produced thereby cancel with each other, thereby compensating for an effect of acceleration, an uppermost acceleration compensating element is formed with a perforation, and a lead wire for deriving the voltage is connected to the electrode of a lower imperforate acceleration compensating piezoelectric element to extend through the perforation of the imperforated element. In a modification, the pressure receiving member is covered by a heat resistant protective layer made of ceramic.
