Correction of measured temperature

Abstract

Abstract PURPOSE:To eliminate the need of a pyrostat for stabilizing the oscillation frequency by a method wherein a temperature detector and a pulse generator for producing clock pulses are provided on the same conditions, a correction amount corresponding to a change in frequency of the clock pulses in accordance with the measured temperature is obtained to correct the counted value, and then the measured temperature is corrected based on this correction amount. CONSTITUTION:A control part CNT composed of a microprocessor, memory, etc. functions to compare a specified address with its own specific address set by an address setting unit AS, upon receiving a boring signal fed through a transmission path L and a transmission circuit SR, and then outputs the data of temperature value in accordance with coincidence of both addresses. Operation mode for a temperature sensor is set by a mode setting unit MS. A quartz oscillator X as a temperature detector includes a zero setting unit ZA for correcting its own characteristic deviation. A pulse generator PG for generating clock pulses is provided to restrict operation of the control part CNT. A display part DP is also provided which indicates the temperature value obtained by the control part CNT.
