FIELD: measuring equipment.
SUBSTANCE: device for measuring temperature refers to the field of information and measurement technology. Device for measuring temperature, containing a sensing element in the form of a thermocouple and an amplifier, a microwave generator with varactor frequency tuning, a constant current source, a rectifier with a regulated voltage, a frequency meter have been introduced. And as an amplifier serves as a magnetic amplifier, and the output of the thermocouple is connected to the control winding of the magnetic amplifier. Working winding of the magnetic amplifier is connected to the AC source and the rectifier input with a regulated voltage. Output of the latter is connected to the first arm (varactor) of the microwave generator, and the second arm of the microwave generator is connected to the output of the constant current source. Output of the microwave generator is connected to the input of the frequency meter.
EFFECT: improvement of the measurement accuracy.
