Isishwankathelo
Umqobo we-thermocouple wokhuseleko lokuzihlukanisa kunye nomsebenzi wokukhusela ukukhuphuka unokudlulisa umqondiso we-millivolt ukusuka kwi-thermocouple (TC) kwindawo enobungozi kwindawo ekhuselekileyo kwi-1: 1.
Le mveliso ifuna unikezelo lwamandla oluzimeleyo, kunye nonikezelo lwamandla olulodwa, igalelo, kunye neetheminali eziphumayo.
"*" imele uhlobo lwegalelo le-thermocouple, kwaye imodeli ethile imelwe yikhowudi (jonga "Udidi loMqondiso woNgeniso kunye neTheyibhile yoRange" ngeenkcukacha).

Ubungakanani
Umzobo weSchematic
Phawula:
1. Umsebenzi kaloliwe wamandla ngumsebenzi ozikhethelayo, kwaye abasebenzisi kufuneka bachaze indlela yonikezelo lwamandla xa bebeka umyalelo.
Ukukhethwa kweziqhagamshelo zikaloliwe zamandla kunokubhekisa kwiphepha lama-89 le "Isihlomelo"
