Izimbangela zamaphutha kumathuluzi okulawula izinga lokushisa Isithando somlilo sikagesi sokulinga

(1) Ngokwejika lesici se-thermocouple ebunjiwe, kungabonakala ukuthi amandla we-thermoelectric wezinto ezimbili ezihlukene ezakha i-thermocouple awahambisani nezinga lokushisa, futhi amanye anomajika amakhulu uma kuqhathaniswa. Ngakho-ke, ukusebenzisa ama-thermocouples ukukala izinga lokushisa nokulungiswa okungewona umugqa nakho kubaluleke kakhulu. Ukuphatha okungalungile kuzoletha amaphutha.

(2) Amandla we-thermoelectric akhiqizwa i-thermocouple awahlobene kuphela nokushisa kokuphela kokulinganisa, kodwa futhi nokushisa kwe-junction ebandayo. Kuphela uma izinga lokushisa le-junction ebandayo lihlala njalo, amandla e-thermoelectric ahlobene kuphela nezinga lokushisa lokuphela kokusebenza. Amathuluzi amaningi anomsebenzi wokunxephezela izinga lokushisa lendawo ebandayo. Uma izinga lokushisa le-ambient lensimbi lingashintshi kakhulu, iphutha elibangelwa isinxephezelo sezinga lokushisa lendawo ebandayo lingashaywa indiva. Kunxeshezelwe ngokugcwele, kuzobe sekwethulwa iphutha elithile. Ku-thermocouple yohlobo lwe-b, njengoba amandla e-thermoelectric engaphansi kuka-3μv ebangeni lika-0~50℃, isinxephezelo sezinga lokushisa akudingekile.

1. Kungabonakala kuthebula lenkomba le-thermocouple ukuthi amandla okukhipha amandla e-thermoelectromotive nge-thermocouple mancane kakhulu. Ukuze kuzuzwe ukulinganisa okunembe kakhudlwana, ngaphezu kokuthuthukisa ukunemba kwethuluzi lokulinganisa, isifunda se-amplifier sangaphandle siyadingeka. , Lokhu kuzophinde kwethule amaphutha.
