Isishwankathelo
Umqondiso we-vibration sensor igalelo kwisithintelo sokhuseleko esizimeleyo, esinokuqonda i-1: 1 ukuhanjiswa okukodwa kwe-voltage ye-voltage engabonakaliyo ephumayo yinzwa ye-vibration kwindawo enobungozi kwindawo ekhuselekileyo, kwaye inokudlulisa izibonakaliso ze-AC kunye ne-DC ngokulandelanayo, inomsebenzi ophezulu wokuchasana nokuphazamiseka.
Le mveliso idinga unikezelo lwamandla oluzimeleyo, kwaye unikezelo lwamandla, igalelo kunye nemveliso yodwa.

Ubungakanani
Imizobo ecwangcisiweyo
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"
