TEMPERATURE MEASURING PROCEDURE Russian patent published in 2002 - IPC

FIELD: measurement technology, measurement of fast varying temperatures with centralized information processing in microprocessor. SUBSTANCE: temperature-sensitive resistor in accordance with temperature measuring procedure is put into tested medium, voltage pulse is fed to input of electric circuit incorporating temperature-sensitive resistor, time interval is recorded, rectangular voltage pulse not causing heating of temperature-sensitive resistor is fed to input of electric circuit. Pulse action is interrupted with change of output signal of electric circuit in the course of fixed time interval from fixed level of output signal. Pulse supply is restored in the course of fixed time interval when value of output signal reaches fixed level. Time interval between moments of pickoff and restoration of input pulse is recorded. EFFECT: reduced sluggishness of temperature measurements when recording output characteristics of signals in the form of time intervals. 1 cl, 2 dwg
