FIELD: instrumentation.
SUBSTANCE: set of devices for measuring the parameters of mechanical vibrations of objects with temperature error compensation is equipped with an additional unit of two capacitors connected in parallel to each other, one of which has a negative temperature coefficient of capacitance, and the second has a zero temperature coefficient of capacitance, whereas an additional unit of capacitors is connected, on the one end, to the signal contact of the piezosensitive element of the piezoelectric vibration transducer, and on the other end, to the signal contact of the cable communication line.
EFFECT: increase in the accuracy of measuring the parameters of mechanical vibrations of mainly high-temperature objects.
