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.

Apparatus for picking-up and analyzing emitted accoustic and ultrasonic

An arrangement for complex diagnosis of internal combustion engines in the course of their operation comprising a control unit, a measuring unit, an operating unit, an evaluation unit and an indication unit, and a transducer for determining parameters such as pressures, vibrations, emitted supersonic signals and temperatures at different positions of the crankshaft and under various engine operating conditions.

Arrangement for complex diagnosis of internal combustion engines

Device for sensing pressure and temperature for making measurements at elevated temperatures without the application of special cooling means. The device comprising a measuring tube with a tensometric winding, and a protecting tube inside this measuring tube provided with a resistance winding for measuring temperatures.

Pressure and temperature sensing device

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.
