I-thermocouple idivayisi yokulinganisa izinga lokushisa ehlanganisa amakhondatha amabili ahlukene athintana endaweni eyodwa noma ngaphezulu. Ikhiqiza i-voltage lapho izinga lokushisa kwelinye lamabala lihluka ekushiseni kwereferensi kwezinye izingxenye zesekethe. Ama-Thermocouples awuhlobo olusetshenziswa kakhulu lwenzwa yokushisa yokulinganisa nokulawula, futhi angaguqula izinga lokushisa libe ugesi. Ama-thermocouples ezohwebo awabizi, ayashintshashintsha, ahlinzekwa ngezixhumi ezijwayelekile, futhi angakala ububanzi obubanzi bamazinga okushisa. Ngokuphambene nezinye izindlela eziningi zokulinganisa izinga lokushisa, ama-thermocouple asebenza ngokwawo futhi awadingi uhlobo lwangaphandle lwenjabulo.
