Iimbangela zeempazamo kwizixhobo zokulawula ubushushu be Isithando soMbane soMfuniselo

(1) Ngokwe-curve yeempawu ze-thermocouple ebunjiweyo, kunokubonwa ukuba amandla e-thermoelectric ezinto ezimbini ezahlukeneyo ezenza i-thermocouple ayihambelani nobushushu, kwaye ezinye zineegophe ezinkulu. Ke ngoko, ukusebenzisa i-thermocouples ukulinganisa iqondo lobushushu kunye nokulungiswa okungahambelaniyo nako kubaluleke kakhulu. Ukungaphathwa kakuhle kuya kuzisa iimpazamo.

(2) Umbane we-thermoelectric owenziwe yi-thermocouple awuhambelani kuphela nobushushu besiphelo sokulinganisa, kodwa kunye nobushushu be-junction ebandayo. Kuphela xa ubushushu bomdibaniso obandayo buhlala buhlala, amandla e-thermoelectric ahambelana kuphela nobushushu bokuphela kokusebenza. Uninzi lwezixhobo zinomsebenzi wembuyekezo yeqondo elibandayo. Ukuba ubushushu be-ambient yesixhobo alitshintshi kakhulu, impazamo ebangelwa yimbuyekezo yeqondo lokushisa elibandayo inokungahoywa. Ihlawulelwe ngokupheleleyo, emva koko impazamo ethile iya kwaziswa. Kuhlobo lwe-b-uhlobo lwe-thermocouple, ekubeni amandla e-thermoelectric angaphantsi kwe-3μv kuluhlu lwe-0 ~ 50℃, imbuyekezo yobushushu ayifuni.

1. Inokubonwa kwitafile yesalathisi se-thermocouple ukuba i-thermoelectromotive force output yi-thermocouple encinci kakhulu. Ukuze ufezekise umlinganiselo ochanekileyo, ngaphezu kokuphucula ukuchaneka kwesixhobo sokulinganisa, isiphaluka se-amplifier yangaphandle siyafuneka. , Oku kuya kwazisa kwakhona iimpazamo.
