ETshayina Ubungakanani obahlukeneyo beChromel iAlumel eBare yoNxibelelwano lweK Uhlobo loBubushushu boVeliso kunye neFactory

Ubungakanani obahlukeneyo ngeChromel yeAlumel eBare ngoNxibelelwano loHlobo lwe-K lweSensom yoMfanekiso oMfaniswayo

Ubungakanani obahlukeneyo be-Chromel Alumel eBare ngoNxibelelwano loHlobo lwe-K lweSensom

Inkcazelo emfutshane:

I-Thermocouple yinzwa esetyenziselwa ukulinganisa ubushushu. I-Thermocouples iquka imilenze yocingo emibini eyenziwe kwiintsimbi ezahlukeneyo. Imilenze yocingo idityaniswe kunye kwelinye icala, idala i-junction. Esi sidibaniso kulapho kulinganiswa ubushushu. Xa i-junction ifumana utshintsho kwiqondo lokushisa, i-voltage yenziwe. Umbane unokutolikwa kusetyenziswa iitafile zereferensi ye-thermocouple ukubala ubushushu.
I-NiCr-NiAl (Uhlobo K) ucingo lwe-thermocouple lufumana olona setyenziso lubanzi kuyo yonke i-basemetal thermocouple, kumaqondo obushushu angaphezu kwama-500 °C.

Ubungakanani obahlukeneyo be-Chromel Alumel eBare ngoNxibelelwano loHlobo lwe-K lweSensom

UHLOBO K (CHROMEL vs ALUMEL) lusetyenziselwa i-oxidizing, inert okanye i-atmosphere eyomileyo yokunciphisa. Ukuvezwa kwi vacuum kuthintelwe kumaxesha amafutshane. Kufuneka ikhuselwe kwi-atmosphere yesulfure kunye ne-oxidizing. Ithembekile kwaye ichanekile kumaqondo obushushu aphezulu.
