摘要

The device for measuring the temperature of an object 12 emitting an infrared radiation, comprises a housing 8 provided with an opening in which is placed a body 4 in temperature by a control apparatus a peltier effect, 6, the body comprising a first part 4a adapted to transmit the ir radiation of the object to a sensor 1 through an optical device 2, 3 and a second part 4b raincoat to the radiation. The optical device is arranged to switch the sensor so as to receive the radiation issued by the two parts of the body, and the output of the sensor means of control of temperature, a closed loop 10 associated with the apparatus a peltier effect, in order to cancel the output signal differential of the sensor, in which case the temperature of the body, which is measured, is a precise indication of that of the object.
