Fe/CuNi Nooca J Thermocouple Alloy Bare Wire
Sharaxaada Alaabta
Nooca J Thermocouple waxaa badanaa loo isticmaalaa qiimihiisa hoose iyo EMF sare Waxaa loo isticmaali karaa xaaladaha oksidaynta ilaa 760°C. Heerkulka sare, waxaa lagu talinayaa in la isticmaalo dhexroor siligga waaweyn.
Heerkulbeegga nooca J wuxuu ku habboon yahay oksaydhaynta, yaraynta jawiga aan firfircoonayn ama faakuumka.
