Ukuhlolisisa
I-Thermocouple input isolation safety barrier ingahlukanisa begodu itjhugulule amatshwayo we-thermocouple (TC) eendaweni eziyingozi ibe ma-4-20mA amatshwayo wamanje, bese uwakhipha endaweni ephephileko. Isithiyo sokuphepha sinokubuyiselwa kwendawo ebandako eyakhelwe ngaphakathi begodu singahlelwa ngokuhlakanipha. Ibanga lamambala le-thermocouple lingasethwa ngesofthiwe yekhomphyutha. Inemisebenzi ye-alamu yokuphuka kwentambo kanye ne-alamu engaphandle kwebanga. Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, okuphakelwa kwamandla okuhlukileko, ukungena, nokukhipha amatheminali. "*" imelela umhlobo wokufaka we-thermocouple, begodu imodeli ethileko imelelwa yikhodi (qala "Umhlobo weSiginali yokufaka kanye nethebula lebanga" ukuthola imininingwana).

Iinqophiso |
|
Ukufaka endaweni eyingozi |
|
Isiginali yokufaka | K, S, E, J, B, T, R, N amatshwayo we-thermocouple (qala "Umhlobo weSignali yokufaka kanye nethebula lebanga" ukuthola imininingwana) |
Ukuvalwa kokufaka | "I-alamu ephasi" engatjhugululwa ibe "yi-alamu ephezulu" ngesofthiwe yokuhlela |
Ibanga lesiginali | Ibanga lokulinganisa le-thermocouple elihambelanako ngu--10~100mV. |
Ibanga lokulinganisa | Abasebenzisi benza ukuhlelwa kwabo lokha naba-oda, begodu bakutjengise kunomboro yomsila nofana ngenye indlela. |
Ukunxephezelwa kokuhlangana okubandayo okwakhelwe ngaphakathi | ±1°C(Ibanga lokubhadela -20°C~ +60°C) |
Umphumela wehlangothi lokuphepha: |
