Abstract

PURPOSE:To reduce the effect of the floating capacity in an apparatus in which an oscillation circuit is connected with a heat-sensitive resistor and a reference resistor to measure temperature, by connecting the reference resistor with a compensating resistor which compensates for the floating capacity generated in the heat-sensitive resistor. CONSTITUTION:A thermistor 12 is secured to the end of a tubular part 34 and connected to an oscillation circuit 14 on a substrate 32 through lead wires 22 and 23. A group of resistors such as a reference resistor are collected as a resistor block 18. Only a variable resistor 11a to be connected to a reference resistor in series is arranged away from the resistor block 18 on the substrate 32 in order to consciously generate a floating capacity in the variable resistor 11a. The length of the wiring and the width thereof on the substrate are set so that said floating capacity is approximately equal to that generated in the thermistor 12.
