Amagama athi "thermowell" kunye "netyhubhu yokukhusela" asetyenziswa ngokuqhelekileyo kumlinganiselo wobushushu kunye nokulawula. Nangona ukusetyenziswa kwazo kufana, kukho ukungafani phakathi kwezi zimbini:

Thermowell:
I-thermowell yityhubhu evaliweyo efakwe kwisitya senkqubo okanye umbhobho ukukhusela inzwa yeqondo lokushisa, njenge-thermocouple okanye i-resistance detector yeqondo lokushisa (RTD), ukusuka kwinkqubo yamanzi. I-Thermowells ivumela i-sensors zeqondo lokushisa ukuba zifakwe kwinkqubo ngelixa zibonelela ngomqobo okhusela inzwa kwi-corrosion, abrasive, okanye i-high-pressure conditions of the process fluid. I-Thermowells yenzelwe ukwahlula inzwa yobushushu kwindawo yenkqubo ngelixa ivumela umlinganiselo ochanekileyo wobushushu.

ityhubhu ekhuselayo:
Ityhubhu ekhuselayo, kwelinye icala, yityhubhu okanye i-sheath esebenza injongo efanayo kwi-thermowell. Isetyenziselwa ukukhusela izinzwa zobushushu ukusuka kwiimeko ezinzima zenkqubo, ezifana nobushushu obuphezulu, i-atmospheres eyingozi okanye i-abrasives. Iityhubhu ezikhuselayo zisetyenziswa ngokuqhelekileyo kwizicelo apho ukuvezwa ngokuthe ngqo kwenzwa yeqondo lokushisa kwindawo yenkqubo kunokubangela umonakalo wenzwa okanye ukufundwa kobushushu obungachanekanga.

Ukushwankathela, ngelixa zombini i-thermowells kunye neetyhubhu zokukhusela zisetyenziselwa ukukhusela i-sensors yeqondo lokushisa, i-thermowells idla ngokuyilwa ngeziphelo ezivaliweyo kwaye zifakwe kwiibhotile okanye iibhobho, ngelixa iibhubhu zokukhusela zixhaphake kakhulu kwaye zinokusetyenziswa kwizicelo ezahlukeneyo. Ilungiselelwe ukukhusela isivamvo seqondo lobushushu kwiindawo ezirhabaxa.
