FIELD: measuring technique.
SUBSTANCE: method comprises changing the frequency of the generator of sinusoidal vibration by means of a heat-depending member in the circuit of exciting of the generator and determining the variation of the value of the temperature heat-dependence of the member as a function of natural frequency of vibration of the vibrating member and generator of sinusoidal vibration. The output signal of the pickup is the dependence of the amplitude on the parameter to be measured.
EFFECT: enhanced precision.
