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).
Imihlobo yesiginali yokufaka kanye nebanga lokulinganisa
| Ikhodi | imodeli ye-TC | Ibanga lokulinganisa | Ibanga eliphasi | Ukunemba kokutjhugulula |
| 1 | K | -200~1370°C | 50°C | 0.5°C/0.1% |
| 2 | S | -50~1760°C | 500°C | 1.5°C/0.1% |
| 3 | KUNYE | -140~1000°C | 50°C | 0.5°C/0.1% |
| 4 | J | -160~1200°C | 50°C | 0.5°C/0.1% |
| 5 | B | 250~1800°C | 500°C | 1.5°C/0.1% |
| 6 | T | -200~400°C | 50°C | 0.5°C/0.1% |
| 7 | R | -50~1760°C | 500°C | 1.5°C/0.1% |
| 8 | N | -200~1300°C | 50°C | 0.5°C/0.1% |
Isibonelo: lokha nakufakwako kune-input ezi-2 ezine-K-couple, izinga lokutjhisa lingu-0~1200°C, okuphumako oku-2 kungu-4~20mA, ukuphakelwa kwamandla ku-20~35VDC, khona-ke imodeli kufanele ibe yi-PHD-22TT-1111 (0~1200°C).
Ibanga lokulinganisa lingasethwa ku-0 ~ 1200℃ ngekhomphyutha.
* Ukuphakelwa kwamandla wetheminali yebhasi, sibawa uqale isithasiselo ukuthola imininingwana.
