Ii-thermocouples zezinye zezona ntlobo zeenzwa zobushushu ezisetyenziswa kakhulu kwihlabathi liphela. Zithandwa kakhulu kwiinkalo ezahlukeneyo ngenxa yoqoqosho lwazo, ukuqina kwazo kunye nokuguquguquka kwazo. Ukusetyenziswa kwe-thermocouple kuqala kwiiseramikhi, iigesi, iioyile, iintsimbi, iglasi kunye neplastiki ukuya ekutyeni naseziseloni.
Ungazisebenzisa naphi na ukujonga ngokuchanekileyo okanye ukurekhoda idatha yobushushu. Ii-thermocouples zaziwa ngokuvelisa umlinganiselo wobushushu ophendula ngokukhawuleza kunye nokumelana okuhle kakhulu nomothuko, ukungcangcazela kunye nobushushu obuphezulu.
I-thermocouple sisiva-luvo esisetyenziselwa ukulinganisa ubushushu kwizicelo zesayensi, ezemveliso, kunye nezobuchwepheshe. Yenziwa ngokudibanisa iingcingo ezimbini zesinyithi ezahlukeneyo ukuze zenze i-junction. I-junction idala i-voltage eqikelelweyo kuluhlu oluthile lobushushu. Ii-thermocouples zihlala zisebenzisa i-Seebeck okanye i-thermoelectric effect ukuguqula i-voltage ibe yi-temperature measurement.
Ii-thermocouples zisetyenziswa kakhulu kwishishini lokutya neziselo ezifana nokufaka i-pasteurization, ukupholisa, ukubilisa, ukwenza ubhiya kunye nokuzifaka ebhotileni. Akunyanzelekanga ukuba ukhathazeke xa usebenzisa i-thermocouple temperature gauge kuba ibonelela ngokufundwa kobushushu obuchanekileyo bokuqhotsa kunye nokupheka ukuqinisekisa ukuba ukutya kwakho kuphekiwe.
Ii-thermocouples zihlala zisetyenziswa kwizixhobo zokutyela ezifana nee-grill, ii-toaster, ii-deep fryers, ii-heater, kunye nee-oven. Ukongeza, ungafumana ii-thermocouples ngendlela yee-temperature sensors kwizixhobo zasekhitshini ezisetyenziswa kwizityalo ezinkulu zokulungisa ukutya.
Ii-thermocouples zikwasetyenziswa kwiindawo zokwenza ubhiya kuba ukuveliswa kwebhiya kufuna amaqondo obushushu achanekileyo ukuze kubiliswe ngokufanelekileyo kwaye kuthintelwe ungcoliseko lweentsholongwane.
Ukulinganisa ubushushu obuchanekileyo beentsimbi ezinyibilikisiweyo ezifana nentsimbi, i-zinc kunye ne-aluminium kunokuba nzima ngenxa yobushushu obuphezulu kakhulu. Iisensa zobushushu ezisetyenziswa kakhulu kwiintsimbi ezinyibilikisiweyo ziintlobo zeplatinum thermocouples B, S kunye no-R kunye neentlobo ze-base metal thermocouples K kunye no-N. Ukukhetha uhlobo olufanelekileyo kuya kuxhomekeka kububanzi bobushushu besicelo esithile esinxulumene nesinyithi.
Ii-thermocouples zesinyithi ezisisiseko zihlala zisebenzisa i-US No. 8 okanye No. 14 (AWG) wire gauge enetyhubhu yesinyithi kunye ne-ceramic insulator. Ii-thermocouples zeplatinum, kwelinye icala, zihlala zisebenzisa ububanzi be-#20 ukuya kwi-#30 AWG.
Ukuveliswa kweemveliso zeplastiki kufuna ulawulo oluchanekileyo lobushushu. Ii-thermocouples zihlala zifuneka ukulawula ubushushu kwiindawo ezahlukeneyo zokucubungula iiplastiki. Zisetyenziselwa ukulinganisa ubushushu obunyibilikayo okanye obuphezulu kwii-injection molds kunye nee-injection molds.
Ngaphambi kokuba usebenzise ii-thermocouples ekucutshungulweni kweeplastiki, kufuneka wazi ukuba kukho iintlobo ezimbini zee-thermocouples kushishino lweeplastiki. Udidi lokuqala lubandakanya imilinganiselo. Apha, ii-thermocouples zingasetyenziselwa ukumisela umsebenzi wokudlulisa ubushushu beeplastiki ngokuxhomekeke kwicandelo lazo elinqamlezileyo. Khumbula ukuba i-thermocouple kufuneka ibone umahluko kumandla asetyenziswayo, ikakhulu ngenxa yesantya kunye necala layo.
Ungasebenzisa ii-thermocouples kuphuhliso lwemveliso kushishino lweplastiki. Ngoko ke, uhlobo lwesibini lokusetyenziswa kwee-thermocouples kushishino lweplastiki lubandakanya uyilo lwemveliso kunye nobunjineli. Ekuphuhlisweni kwemveliso, kufuneka usebenzise ii-thermocouples ukubala utshintsho lobushushu kwizinto, ingakumbi ngexesha lobomi bemveliso.
Iinjineli zinokukhetha ii-thermocouples ezifanelekileyo kwizixhobo abazisebenzisayo ekwenzeni iimveliso zabo. Ngokufanayo, zingasebenzisa ii-thermocouples ukuvavanya ukusebenza koyilo. Oku kuya kubavumela ukuba benze utshintsho ngaphambi kokuba inkqubo yemveliso iqale.
Iimeko ze-furnace zimisela kakhulu i-thermocouple efanelekileyo ye-oven yelabhoratri enobushushu obuphezulu. Ke ngoko, ukuze kukhethwe i-thermocouple efanelekileyo, kufuneka kuqwalaselwe izinto ezininzi, ezinje:
Kwiimeko ezininzi, ii-extruders zifuna uxinzelelo oluphezulu kunye nobushushu obuphezulu. Ii-thermocouples zee-extruders zine-adapters ezinemisonto ezinceda ukubeka iincam zazo ze-probe kwiplastiki enyibilikisiweyo, zihlala ziphantsi koxinzelelo oluphezulu.
Ungazivelisa ezi thermocouples njengezinto ezi-single okanye ezi-double ezinee-housings ezi-single threaded. Ii-thermocouples ze-bayonet (BT) kunye nee-thermocouples ze-compression (CF) zisetyenziswa kakhulu kwiindawo ezikhupha izinto ezinoxinzelelo oluphantsi.
Iindidi ezahlukeneyo zee-thermocouples zinezicelo ezininzi kumashishini ahlukeneyo. Ngoko ke ukuba usebenza kubunjineli, kwintsimbi, ekutyeni naseziseloni, okanye ekucubunguleni iiplastiki, uya kufumanisa ukuba ii-thermocouples zisetyenziswa kakhulu ekulinganiseni ubushushu nokulawula.
