OPTICAL PYROMETRIC TRANSDUCER Russian patent published in 2015 - IPC G01J5/02 

FIELD: instrumentation.

SUBSTANCE: invention relates to temperature measurements by optical methods. Optical pyrometric transducer comprises case, optical system including lens, photoelectrical converter, system of cooling with coolant pumped there through, thermoelectrical microrefrigerator including radiator, thermoelectric microgerenerator to feed said thermoelectrical microrefrigerator including radiator, heat insulator and radiator. Optical system is rigidly connected with photoelectric converter case and microrefrigerator cold junction. The latter is connected to radiator, the first one along radiation flux. Second radiator is coupled with microgenerator cold junction to make the coolant pumping cavity with said first radiator. Third radiator is secured to microgenerator hot junction and arranged in the area of ambient temperatures effects.

EFFECT: higher accuracy and reliability.
