Description: Design by single chip microcomputer as the core of the system of intelligent, measured thermocouple and standard thermocouple after verification furnace in bound, the output leads through the compensation conductor BingPing introduced in the cold end temperature compensation Be measured with each inspection standard thermocouple thermocouple temperature point of thermoelectric potential by low signal potential data acquisition circuit made, and in its acquisition circuit to amplify, A/D conversion processing, into single chip can identify the digital quantity into SCM processing SCM through the execution procedures, calculates the measured accidentally and standard of the biggest accidentally thermoelectric potential deviation, and then and maximum allowable deviation, in comparison to figure out whether tested thermocouple qualified and the completion of the automatic verification of thermocouples.
