FIELD: the invention refers to electric schemes of switching with a thermistor which has a negative temperature coefficient.
SUBSTANCE: the mode includes transformation of temperature in voltage with direct and reverse temperature characteristics. After that one can receive difference output voltage proportional to measured temperature. The arrangement has a source of reference voltage, two channels of transformation of temperature into voltage and algebraic summation unit.
EFFECT: the invention is designed to increase accuracy of measuring of temperature at the expense of increasing linear characteristics of transformation at securing possibility of interchangeability of thermo sensitive elements.
