Isishwankathelo

Umqobo wokhuseleko wokufakwa kwe-thermocouple ungadlulisela isignali ye-millivolt ukusuka kwi-thermocouple (TC) kwindawo eyingozi ukuya kwindawo ekhuselekileyo nge-1: 1.

Le mveliso ifuna umbane ozimeleyo, kunye nombane ohlukeneyo, i-input, kunye nee-output terminals.

"*" imele uhlobo lokufaka lwe-thermocouple, kwaye imodeli ethile imelwe yikhowudi (jonga "Uhlobo lweSignali yokungenisa kunye neTheyibhile yoLuhlu" ukuze ufumane iinkcukacha).

Iintlobo zesignali yokufaka kunye noluhlu lokulinganisa

Ubukhulu

Umzobo wesicwangciso

Phawula:

1. Umsebenzi wesitimela samandla ngumsebenzi onganyanzelekanga, kwaye abasebenzisi kufuneka bachaze indlela yokubonelela ngombane xa bebeka iodolo

Ukukhethwa kwezihlanganisi zesitimela samandla kunokubhekisa kwiphepha lama-89 le "Annex"
