Abstract

PURPOSE: To measure temperature with high accuracy and less power consumption, by intermittently using the frequency of the oscillation circuit using Y-cut crystal oscillator.
CONSTITUTION: When the pulse a having the width of 2 seconds every 100 second period from the timing pulse generating circuit 3, is fed to the power supply circuit 2, each circuit operates for 2 seconds. At the period of the pulse C having the width of one second simultaneously produced with the circuit 3, by using the Y-cut crystal oscillator, the output pulse of the crystal oscillation circuit 5 in which the oscillation frequency is in proportional to the temperature is fed to the counter of the discrimination circuit 7 via the frequency division circuit 6 and the discrimination signal q is fed to the operation circuit 9 depending on the polarity of temperature according whether the count value is more than a given value or not. When the gate circuit 8 is open with the pulse d from the circuit 3 immediately after the period of pulse C is elapsed, the pulse from the circuit 6 is fed to the operation circuit 9 for the period of the pulse e of width of one second caused by the circuit 3 together with the pulse d, and the circuit 9 performs subtraction with a given value depending on the signal q to calculate the temperature. Accordingly, the temperature can be measured with high accuracy and less power consumption.
