Iintambo zembuyekezo ze-thermocouple nazo zinokubizwa ngokuba ziintambo zesixhobo, kuba zisetyenziselwa ukulinganisa ubushushu benkqubo. Ulwakhiwo luyafana nentambo yesixhobo sokusebenza kodwa isixhobo somqhubi sahlukile. I-Thermocouples isetyenziswa kwiinkqubo zokuva ubushushu kwaye iqhagamshelwe kwiipyrometers ukubonisa kunye nokulawula. I-thermocouple kunye nepyrometer ziqhutywa ngombane ngeentambo zokwandisa i-thermocouple / i-thermocouple compensating cables. Ii-conductor ezisetyenziselwa ezi ntambo ze-thermocouple kufuneka zibe neempawu ezifanayo ze-thermo-electric (emf) njengaleyo ye-thermocouple esetyenziselwa ukuva ubushushu.
Uhlobo T Thermocouple (Ubhedu + /Constantan–) T luluhlu olumxinwa kunye nokuchaneka okuphezulu kocingo lwe-thermocouple. Iyathandwa kwinzululwazi kunye nofakelo esweni ubushushu bezonyango . Ukuchaneka kwayo ± 1 ° C / 2 ° F kwimida eqhelekileyo kunye ± 0.5 ° C / 1 ° F kwimida ekhethekileyo, kwaye inoluhlu lobushushu -330 ° F ~ 662 ° F (-200 ° C ~ 350 ° C) ngokuxhomekeke kubungakanani begeyiji yocingo.
Isityalo sethu sivelisa uhlobo lwe-KX, NX, EX, JX, NC, TX, SC/RC, KCA, KCB imbuyekezo yocingo lwe-thermocouple, kwaye zisetyenziswa kwizixhobo zokulinganisa ubushushu kunye neentambo. Iimveliso zethu zembuyekezo ze-thermocouple zonke zenziwe zithobela i-GB/T 4990-2010 'Iingcingo ze-alloy zolwandiso kunye neentambo zembuyekezo ze-thermocouples' (uMgangatho weSizwe waseTshayina), kunye ne-IEC584-3 'Inxalenye ye-Thermocouple i-3-compensating wire' (umgangatho wamazwe ngamazwe).
Ukumelwa komqathango. ucingo: ikhowudi ye-thermocouple+C/X, umz. SC, KX
X: Kufutshane ukwandiswa, kuthetha ukuba i-alloy yocingo lwembuyekezo iyafana nealloyi ye-thermocouple.
C: Ifutshane kwimbuyekezo, ithetha ukuba i-alloy yocingo lwembuyekezo ineempawu ezifanayo kunye ne-alloy ye-thermocouple kwiqondo elithile lobushushu.
Isicelo:
1. Ukufudumeza - Izitshisi zegesi kwii-oveni
2. Ukupholisa – Izikhenkcezisi
3. Ukukhuselwa kwe-injini - Amaqondo obushushu kunye nobushushu bomhlaba
4. Ulawulo lobushushu obuphezulu – Ukufakwa kwentsimbi
