FIELD: measuring technique.
SUBSTANCE: instrument comprises generator, capacitive pickup connected with the generator, temperature gage, microprocessor connected with the indicator, and diode-resistive cell. The diode-resistive cell is connected between the capacitive pickup and microprocessor. The microprocessor has built-in analogue-digital converter and store. The generator is made of a generator of rectangular pulses. The temperature gage is made of a semiconductive resistance connected to the circuit of power supply to the generator. The instrument has separating capacitor connected to the circuit of power supply to the pickup. The capacitive pickup is made of a pickup whose electrodes are separated by means of bearing members.
EFFECT: enhanced reliability.
