DEVICE FOR TEMPERATURE MEASUREMENT Russian patent published in 2015 - IPC G01K7/02 G01K7/13 

FIELD: measurement equipment.

SUBSTANCE: device for measurement of temperature comprises a bridge assembled on resistors R1, R2, R3, R4, fed from a source of stabilised voltage U_stab (points b, c). To the measurement diagonal of the bridge (points a, d) there is a negative electrode of a thermocouple connected, and a runner (slider) of a potentiometer R5, connected via an inlet circuit of an amplifier 6 with a positive electrode of a thermocouple. The output of the amplifier 6 via serially connected a generator of controlled frequency 7, and a converter of frequency into voltage 8 is connected to outputs of the potentiometer R5, the first output of which is connected to the input of the amplifier 6, and the output of the generator 7 is connected also to the outlet F_out of the device.

EFFECT: increased efficiency and reliability of a device.
