A nwekwara ike ịkpọ eriri nkwụnye ụgwọ thermocouple dị ka eriri ngwá ọrụ, ebe ọ bụ na a na-eji ya maka nhazi okpomọkụ.Ihe owuwu ahụ yiri eriri ngwaọrụ ejikọtara ọnụ mana ihe nchịkwa dị iche.

A na-eji thermocouples eme ihe na usoro iji hụ okpomọkụ ma jikọọ ya na pyrometers maka ngosi na njikwa.A na-eduzi thermocouple na pyrometer site na eriri ọkụ thermocouple / thermocouple na-akwụ ụgwọ.Ndị na-eduzi ndị a na-eji maka eriri thermocouple ndị a ka achọrọ ka ha nwee ihe ndị yiri ya na thermo-electric (emf) dị ka nke thermocouple eji maka ịhụ okpomọkụ.
