Detaljerad förklaring av kalibreringsmetoden för pansrade termoelement

Verification method and device for rapid armored thermocouples of metal melts. The device is mainly composed of a flat ring that can contain the quartz tubes at the ends of the two measured pairs, two armored thermocouples with the same shape as the measured pairs, and a corresponding temperature control display output device. The verification method is to first use two calibration thermocouples to find the points in the flat ring that make the thermoelectric potential of the two calibration pairs the same, and replace one of the calibration pairs with the measured pair. Under the condition that other conditions are stable, after the reading of the measured pair is stable, it is compared with the reading of the calibration pair to know whether the value of the measured pair is correct. This method provides a laboratory verification method for rapid temperature measurement thermocouples, som kan testa snabb temperaturmätningstermoelement vid flera temperaturpunkter och göra en omfattande utvärdering .

Dess egenskaper är:

A . enheten består av en platt ring, ett par kalibreringsansvarade termoelement och en temperaturkontrolldisplayutgång .

b. The verification method is to first pull out the two calibration thermocouples from both ends of the adding coil to make the hot ends of the sheathed thermocouples touch each other. By changing the position of the calibration thermocouple in the adding coil, the thermoelectric potentials of the two calibration thermocouples are made the same. Replace one of the Kalibreringstermoelement med det uppmätta snabba termoelementet, läs dess termoelektriska potentialvärde i ett stabilt tillstånd och jämför det med den termoelektriska potentialen för kalibreringstermoelementet för att känna till noggrannheten för det uppmätta snabba mantelformade termoelementet .
