Isishwankathelo
Igalelo lokumelana ne-Thermal Izithintelo zokhuseleko ezizimeleyo zinokusasaza i-thermal resistor (RTD) Pt100 ye-two-wire okanye i-3-wire kwindawo eyingozi kwindawo ekhuselekileyo 1:1.
Le mveliso ifuna unikezelo lwamandla oluzimeleyo, kunye nonikezelo lwamandla olulodwa, igalelo, kunye neetheminali eziphumayo.

Ubungakanani
Umzobo wocingo
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"
2. Xa ufaka i-RTD yocingo oluthathu, kuyimfuneko ukuqinisekisa ukuba iingcingo ezintathu zinobude obulinganayo kangangoko kunokwenzeka.
3. Xa ufaka i-RTD yeentambo ezimbini, i-terminals barrier barrier terminals 4 kunye ne-2 kufuneka ibe yifutshane.
