DEVICE DETERMINING TEMPERATURE Russian patent published in 2003 - IPC

FIELD: thermometry, remote technological control over temperature regimes of rolling mill. SUBSTANCE: device determining temperature includes IR detectors, background radiator, signal processing unit, indication unit, two full radiators with temperature-sensitive elements. First radiator is optically coupled to IR detector through switch of optical channels. Second full radiator is optically coupled to second IR detector through switch of optical channels and specular reflector. Outputs of first and second IR detectors are connected to first and second inputs of signal processing unit through first matching amplifier to first phase-sensitive detector and through second matching amplifier to second phase-sensitive detector connected in series. Third and fourth inputs of signal processing unit are connected to outputs of first and second temperature-sensitive elements of full radiators. Output of reference voltage generator is connected to fifth input of signal processing unit and to second inputs of phase-sensitive detectors. Sixth input of signal processing unit is connected to output of temperature-sensitive element of background radiator. EFFECT: expanded functional potential of device. 1 dwg
