  • Apparatus for picking-up and analyzing emitted accoustic and ultrasonic signals in hollow bodies
    Patent number: 4459850
    Abstract: Apparatus for picking-up and analyzing emitted accoustic and ultrasonic signals by means of a piezoelectric pick-up element connected to an amplifier with high input resistance, the output of the amplifier being connected for further evaluation to selective circuits and to an evaluation device. The piezoelectric pick-up element is situated in a casing, said casing being fixed to a hollow body being tested as by a strap encompassing at least partly both the casing and the tested hollow body.

  • 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.
