Abstract

PURPOSE:To enable the high-precise measurement of temperature for a short time, by a method wherein a plural number of adders are connected in series between a temperature measuring probe and an indicator, and an addition value computation circuit, which differentiates an input to be added and multiplies by a specific constant, is annexed to each of the adders. CONSTITUTION:A plural number of adders are connected in series between a temperature sensitive probe, incorporating a temperature measuring resistor, and an indicator, and an addition value compensation circuit, which differentiates an input to be added and multiplies the result by a constant being below 2 times an instrinsic temperature measuring time constant of an object to be measured, is annexed to each of the adders to constitution an electronic thermometer. For example, an output of a temperature sensitive probe 1 having a temperature measuring resistor 2 is amplified by an amplification circuit 3, the output is transmitted to an adder 4 and an addition value computation circuit 5, the latter multiplies the differentiation value of the output by a predetermined constant, and the result is sent to said adder where it is added to said output. Through the repetition of the same operations according to the number of the adders, the rise of the output indicated in an indicator 16 becomes steep, which results in enabling the high-precise measurement of temperature for a short time.
