Abstract
PURPOSE: To unnecessitate the setting of a standard conditions by setting approximate standard conditions in combination with a standard resistor having a small temperature coeffiecient as compared with a standard thermister and the same resistance value and calibrating the sensor circuit with respect to the difference between the set standard condition and the actual condition.
CONSTITUTION: When the output of a multivibrator 11 is positive, switches 5 and 7 are closed, and switches 6 and 8 are opened. When the output of the multivibrator 11 is negative, the switches are reversed. The duty cycle of the multivibrator 11 is controlled by the output of an integrator 9, and the output average voltage of the integrator 9 is maintained at a predetermined reference potential by a thermistor 13 and standard resistor 14. Accordingly, when a variable resistor 20 is adjusted so that the output average voltage of an integrator 10 becomes a predetermined reference voltage, the variable resistor 20 is adjusted to the resistance value under the standard condition of a thermistor 19.
