ThIi-ermocouples zisetyenziswa ngokubanzi njengezinto zesivamvo seqondo lobushushu kushishino nakwizicelo zenzululwazi ngenxa yobunzima bazo, uluhlu olubanzi lobushushu, kunye nexesha lokuphendula ngokukhawuleza. Nangona kunjalo, umngeni oqhelekileyo kunye ne-thermocouples sisidingo sembuyekezo ye-junction ebandayo. IThermocoupleivelisa amandla ombane ngokomlinganiselo wobushushu phakathi kwesiphelo sayo sokulinganisa (isiphelo esishushu) kunye nesiphelo sesalathiso sayo (isiphelo esibandayo). Indawo ekudityanwa kuyo ireferensi idla ngokufumaneka kwi-terminal yegalelo lesixhobo sokulinganisa, kwaye ubushushu bayo bungaguquguquka ngenxa yeemeko zokusingqongileyo. Olu tshintsho kwiqondo lokushisa elibandayo linokubangela iimpazamo zokulinganisa ubushushu.
Imbuyekezo ye-Cold junction yinkqubo yokulinganisa ngokuchanekileyo ubushushu besiphambuka esibandayo kunye nokubuyisela umphumo wayo kwimveliso yombane we-thermocouple. Oku kubalulekile ekufezekiseni imilinganiselo yobushushu echanekileyo, ngakumbi kwizicelo ezifuna ulawulo oluchanekileyo lobushushu. Ukuphumeza imbuyekezo ye-junction ebandayo ibalulekile ekuqinisekiseni ukuchaneka kunye nokuthembeka kwemilinganiselo yobushushu be-thermocouple. Ngaphandle kwembuyekezo eyiyo, iimpazamo ezibalulekileyo zingenzeka kufundo lwamaqondo obushushu, ngakumbi kwiindawo ezinobushushu obungazinzanga kwicala elibandayo.
Kukho iindlela ezininzi zokufezekisa imbuyekezo ye-junction ebandayo, enye indlela eqhelekileyo kukusebenzisa i-thermocouple signal conditioner. Ezi zixhobo zenzelwe ukulinganisa iqondo lokushisa elibandayo kunye nokubonelela ngembuyekezo efunekayo kwimveliso yombane we-thermocouple. Iimpawu zeempawu zingaphunyezwa njengeeyunithi ezizimeleyo okanye zihlanganiswe kwizixhobo zokulinganisa. Ukulungiswa komqondiso kufuphi nesiphambuka esibandayo singasetyenziselwa ukunciphisa iimpazamo kwimilinganiselo yokushisa ngaphezu kokusebenzisa i-conditioner yesignali ezinikeleyo. Ngokusebenzisa iindlela ezifanelekileyo zokucoca kunye nokukhulisa kufutshane nesiphambuka esibandayo, imveliso yombane we-thermocouple inohlengahlengiswa ukunciphisa iziphumo zokutshintsha kobushushu besiphambuka esibandayo.
I-Shanghai Wangyuan Instruments of Measurement Co., Ltd. yinkampani yaseTshayina yodidi oluphezulu lweshishini eligxile kubuchwephesha bolawulo lwenkqubo yoshishino kunye neemveliso iminyaka engaphezu kwama-20. Sinokubonelela ngokuchaneka nokuthembekileyoabathumeli bobushushungezinto ezizivayo zesiphambuka esibandayo sihlawulelwe thermocouple ngokunjaloumqobo wokhuseleko okrelekrelekunye nomsebenzi wembuyekezo obandayo ozenzekelayo. Zive ukhululekile ukuqhagamshelana nathi ngolwazi oluthe vetshe.
