Device for automatically measuring T12 type iron core thermocouple coefficient and application method thereof

Abstract

The invention relates to a device for automatically measuring a T12 type iron core thermocouple coefficient and an application method thereof. After full contact between the T12 type iron core and a K type standard thermocouple, the T12 type iron core is heated, heat is conducted to the K type standard thermocouple, a voltage of the K type standard thermocouple is measured through utilizing a microprocessor control circuit, temperature of the iron core is acquired according to a thermocouple coefficient, and a thermocouple voltage of a to-be-measured T12 type iron core is further measured; an energization current of the T12 type iron core is automatically controlled for heating the T12 type iron core to have different temperatures, thermocouple voltages of the T12 type iron core under the different temperatures are measured repeatedly, a voltage and temperature coefficient table of the thermocouple in the T12 type iron core is lastly acquired, and the coefficient table is outputted to an operation control end through a USB interface. The device is advantaged in that the temperature of the iron core can be adjusted according to demands, the temperature is controlled in a certain scope, performance of the iron core can be prevented from being damaged by over-high temperature, and problems of incapability in automatic measurement, inaccurate data and inconvenient operation existing in an iron core thermometric indicator in the prior art are solved.
