FIELD: measurement equipment.
SUBSTANCE: converter of temperature into voltage comprises a serially connected thermocouple and an amplifier, a source of reference voltage, which is an output is connected to the first input of a summator, and also an analogue dividing device and a differential amplifier, connected in series via a direct input of a differential amplifier, and also the first scale converter and the second scale converter, with the input connected to the first input of the summator, and with the output - to an inverting input of the differential amplifier. The output of the amplifier via the first scale converter is connected to the second input of the summator, and the output of the summator is connected to the second output of the analogue dividing device. The input of the square-ware generator is connected with the output of the amplifier and the input of the first scale converter, and the output is connected to the first input of the analogue dividing device.
EFFECT: improved accuracy of operation of a converter of temperature into voltage with the possibility of its tuning and calibration.
