Makulidwe Osiyanasiyana Chromel Alumel Bare Waya wa K Type Temperature Sensor

Kufotokozera Kwachidule:

Thermocouple ndi sensa yomwe imagwiritsidwa ntchito kuyeza kutentha. Ma thermocouples amakhala ndi miyendo iwiri yamawaya opangidwa kuchokera kuzitsulo zosiyanasiyana. Miyendo ya mawaya imalumikizidwa pamodzi mbali imodzi, kupanga mphambano. Pa mphambano iyi ndipamene amayezera kutentha. Pamene mphambanoyo imasintha kutentha, magetsi amapangidwa. Vutoli limatha kutanthauziridwa pogwiritsa ntchito matebulo ofotokozera a thermocouple kuwerengera kutentha.
Waya wa NiCr-NiAl (Mtundu wa K) wa thermocouple amapeza kugwiritsidwa ntchito mokulirapo mu thermocouple yonse yoyambira, pa kutentha pamwamba pa 500 °C.

Makulidwe Osiyanasiyana Chromel Alumel Bare Waya wa K Type Temperature Sensor

TYPE K (CHROMEL vs ALUMEL) imagwiritsidwa ntchito popanga oxidizing, inert kapena youma kuchepetsa atmospheres. Kuwonekera kwa vacuum kumangokhala kwakanthawi kochepa. Ayenera kutetezedwa ku sulfure komanso oxidizing atmospheres. Odalirika komanso olondola pa kutentha kwakukulu.
