Hakanan ana iya kiran igiyoyin diyya na thermocouple azaman igiyoyin kayan aiki, tunda ana amfani da su don auna zafin jiki. Ginin yana kama da kebul na kayan aiki guda biyu amma kayan jagora ya bambanta.

Ana amfani da thermocouples a cikin matakai don fahimtar zafin jiki kuma an haɗa su da pyrometers don nuni da sarrafawa. Thermocouple da pyrometer ana gudanar da su ta hanyar lantarki ta hanyar igiyoyi masu tsawo na thermocouple / thermocouple ramuwa. Ana buƙatar masu gudanarwa da aka yi amfani da su don waɗannan igiyoyin thermocouple su kasance da irin abubuwan da ake amfani da su na thermo-electric (emf) kamar na thermocouple da ake amfani da su don gano yanayin zafi.

Our shuka yafi kerarre irin KX, NX, EX, JX, NC, TX, SC / RC, KCA, KCB diyya waya ga thermocouple, kuma suna amfani da zazzabi auna kida da igiyoyi. Samfuran mu na ramawa na thermocouple duk an yi su ne ta hanyar GB/T 4990-2010 'Alloy wayoyi na tsawaitawa da igiyoyin biyan diyya don thermocouples' (Ma'aunin Kasa na kasar Sin), da kuma IEC584-3 'Thermocouple part 3-compensating waya' (International Standard).
