China Yosiyanasiyana Chromel Alumel Waya Wopanda Waya wa K Type Temperature Sensor Kupanga ndi Kupanga Fakitale

Makulidwe Osiyanasiyana Chromel Alumel Waya Wopanda Chingwe cha Sensor Yotentha Mtundu wa K Chithunzi Chowonetsedwa

Makulidwe Osiyanasiyana a Chromel Alumel Bare Waya wa Sensor Yotentha ya Mtundu wa K

Kufotokozera Kwachidule:

Thermocouple ndi sensa yomwe imagwiritsidwa ntchito poyesa kutentha. Ma thermocouple amakhala ndi miyendo iwiri ya waya yopangidwa kuchokera ku zitsulo zosiyanasiyana. Miyendo ya mawaya imalumikizidwa pamodzi kumapeto amodzi, ndikupanga malo olumikizirana. Malo olumikizirana awa ndi komwe kutentha kumayesedwa. Malo olumikizirana akasintha kutentha, magetsi amapangidwa. Mphamvu yamagetsi imatha kumasuliridwa pogwiritsa ntchito matebulo ofotokozera kutentha kwa thermocouple kuti awerengere kutentha.
Waya wa thermocouple wa NiCr-NiAl (Type K) umagwiritsidwa ntchito kwambiri mu thermocouple yonse ya basemetal, kutentha kopitilira 500 °C.

TYPE K (CHROMEL vs ALUMEL) imagwiritsidwa ntchito mumlengalenga wothira okosijeni, wosagwira ntchito kapena wouma. Kukhudzidwa ndi vacuum kumangokhala kwa nthawi yochepa. Iyenera kutetezedwa kumlengalenga wothira okosijeni komanso wothira okosijeni pang'ono. Yodalirika komanso yolondola pa kutentha kwambiri.
