Tuam Tshoj Chromel constantan hlau E hom Thermocouple hlau (hom EP EN) Chaw Tsim Khoom thiab Hoobkas

Hlau Chromel constantan E hom Thermocouple hlau (hom EP EN)

Kev Piav Qhia Luv:

NiCr-CuNi thermocouple hlau (hom E) kuj hu ua NiCr-Constantan thermocouple hlau. Nws muaj lub teeb liab muaj zog dua & qhov tseeb 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 tseeb.
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.
Thermocouple ribbon hlau, rods, strips tuaj yeem muab raws li koj qhov kev thov.

Lub Thermocouple yog dab tsi?
Lub Thermocouple yog ib lub sensor siv los ntsuas qhov kub. Cov Thermocouple muaj ob ceg hlau ua los ntawm ntau hom hlau. Cov ceg hlau raug vuam ua ke ntawm ib kawg, tsim ib qho kev sib tshuam. Qhov kev sib tshuam no yog qhov uas ntsuas qhov kub. Thaum qhov kev sib tshuam muaj kev hloov pauv ntawm qhov kub, lub zog hluav taws xob raug tsim. Lub zog hluav taws xob ces tuaj yeem txhais tau los ntawm kev siv cov lus qhia thermocouple los xam qhov kub.
