Xasaasiyada kuleylka waxaa loo isticmaalaa geedi socodka si loo dareemo heerkulka oo ku xiran pyrometariyaasha si loo baaro oo loo xakameeyo. Thermocouple iyo pyrometer-ka waxaa lagu sameeyaa fiilooyinka fidsan ee fidsermoup / thermocouple magdhow fiilooyinka. Himiladaha loo isticmaalo fiilooyinka thermococople-ka waxaa looga baahan yahay inay yeeshaan guryaha korantada ee korantada (EMF) oo la mid ah kuwa heerkulka ah ee loo isticmaalo dareenka heerkulka. Dhirtayada ugu badnaan noocyada soo saarka kh, nx, ex, jx, nc, tx, tx, sc ,,,,,,,,,,,,,,,,,, waxaa loo adeegsadaa qalabka sicirka heerkulka iyo fiilooyinka. Kormeerkayaga lacagta ah ee alaabada la siiyo ayaa dhammaantood ay ka dhigaan GB / t 4990-2010 'Sproy Point of kordhinta iyo magdhowga heerarka heerkulka) (STEM584-3' Tusmocoulo Qaybta 3-Hanuumaha (Caalamiga ah. Matalaya koonta. wire: thermocouple code+C/X , eg SC, KX X: Short for extension, means that the compensation wire's alloy is as the same as the the alloy of the thermocouple C: Short for compensation, means that the compensation wire's alloy has similar characters with the thermocouple's alloy in a certain temperature range.
