Abstract

temperature measurement instrument is based on thermocouple, with AT89C51 single chip as kernel. Dedicated chip max6675K for cold junction compensation of thermocouple is adopted to perform cold junction compensation to K-type thermocouple and to perform amplification, AD conversion and digital processing to input signal from T- and T+ end of K-type thermocouple. It is transmitted to single chip by passing through spi serial port. Convert into ROM address after operation processing of single chip. Practical temperature value will be calculated by twice table-finding method and relevant procedure will be called to transmit the temperature value to 4 common-anode LED nixie tube display or outrange alarm. Software of temperature instrument of this thermocouple is compiled with C language and modular construction design is adopted.
