ことを特徴とする温度測定装置。The sensor includes a thermistor oscillation circuit using a thermistor as part of the sensor, and a nearerization circuit that adds a reference oscillation frequency signal to the thermistor oscillation signal to improve the linearity of the temperature-frequency characteristic of the thermistor oscillation signal. In a temperature measuring device equipped with a decoding circuit that converts a signal into a temperature value, the measurement control circuit outputs a measurement control signal to a frequency dividing circuit after a delay of an arbitrary adjustment time from the start of a unit measurement time, and the linearization circuit outputs a measurement control signal to a frequency dividing circuit. A frequency divider circuit that divides the output signal of a predetermined number of stages and subtracts the period of this frequency-divided signal from the measurement control signal and outputs a nearerized output frequency-divided signal, and a counting circuit that outputs a constant pulse signal for counting. The pulse circuit inputs the linearized output frequency-divided signal and the counting pulse signal, and in order to keep the slope of the temperature-frequency characteristic constant, the linearized output frequency-divided signal is applied as a gate signal to the inputted counting pulse at a constant rate. Thinning out or interrupting
- A temperature measuring device characterized by comprising: a decimation interrupt circuit that outputs a signal that has been measured.
