Abstract:

Object of the Invention A contactless method of measuring the true temperatures of heated bodies which has the distinguishing feature that for the purpose of improving the precision of the measurement through the elimination of the effect of the properties of an intervening medium simultaneously, there are used two types of pickups, for example, a semiconductor thermal element and a photoelement or photoresistor with a narrow-band light filter, the signals from which after amplification and differentiation are compared inside each channel with the derivative of the time signal, after which the signals are compared with each other, and the results of the comparison are taken from an automatic recording instrument.
