  • Piezoelectric pick-up device for measuring pressures within hollow bodies
    Patent number: 3942049
    Abstract: Piezoelectric pick-up device for measuring internal overpressure of hollow bodies such as cylindrical pipes. The device has similar parts which present a cavity therebetween with a circular cross section with a circular groove. Within the groove there is disposed an insert composed of four parts, said insert encompassing the hollow body and transmits the deformations of the hollow body due to overpressure therewithin to piezoelectric plates. The four parts of the insert are advantageously made of steel.
