Tankii E hom chromel constantan Bare Thermocouple Hlau

Kev Piav Qhia Luv:

NiCr-CuNi thermocouple (hom E) kuj hu ua NiCr-Constantan thermocouple. Nws muaj lub teeb liab muaj zog dua & raug dua li Hom K lossis Hom J ntawm qhov kub nruab nrab ntawm 1,000F thiab qis dua. Hom E kuj ruaj khov dua li hom K, uas ntxiv rau nws qhov raug.
Hom E thermocouple muaj qhov tso zis EMF loj tshaj plaws thiab qhov rhiab heev siab tshaj plaws, yog li nws zoo tagnrho rau kev ntsuas qhov kub hloov me me. Nws kuj muaj kev ruaj khov zoo hauv qhov kub qis txog li 300ºC, thiab muaj cov khoom zoo ntawm kev tiv thaiv xeb hauv huab cua noo. Nws raug pom zoo rau oxidizing lossis inert atmospheres, tab sis tsis tuaj yeem siv ncaj qha rau hauv kev txo qis huab cua thiab huab cua nrog cov pa roj sulfur.
