Ukuhlolisisa
Isithiyo sokuvikela sokufaka se-RTD singatjhugulula amatshwayo we-thermistor (RTD) weentambo ezimbili nofana ezintathu eendaweni eziyingozi abe matshwayo wamanje we-4-20mA bese uwakhipha endaweni ephephileko. Ingahlelwa ngokuhlakanipha, begodu ububanzi bamambala bokujamelana nokutjhisa bungasethwa 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-thermistor, begodu imodeli ethileko imelelwa yikhodi (qala "Umhlobo weSiginali yokufaka kanye nethebula lebanga" ukuthola imininingwana).
Imihlobo yesiginali yokufaka kanye nebanga lokulinganisa
| Ikhodi | Imodeli ye-RTD | Ibanga lokulinganisa | Ibanga eliphasi | Ukunemba kokutjhugulula |
| 1 | G53 | -50~150°C | 20°C | 0.2°C/0.1% |
| 2 | Cu50 | -50~150°C | 20°C | 0.2°C/0.1% |
| 4 | I-Pt100 | -200~850°C | 20°C | 0.2°C/0.1% |
| 6 | Pt1000 | -200~850°C | 20°C | 0.2°C/0.1% |
| 7 | Ni1000 | -60~250°C | 20°C | 0.2°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.

Qaphela: 1. PHD-11TZ - * 1 ayifaki ingcenye yokukhipha 2
2. Umsebenzi we-power rail ngumsebenzi ongakhetha kiwo, begodu abasebenzisi kufuze bacacise indlela yokuphakelwa kwamandla lokha nawufaka i-oda
Ukukhethwa kwezixhumanisi zesitimela samandla kungabhekisa ekhasini 89 le "Isithasiselo"
3. Lokha nawufaka i-RTD yeentambo ezintathu, kuyatlhogeka bona uqinisekise bona iintambo ezintathu iintambo zinobude obulinganako ngendlela ekungakghoneka ngayo
4. Lokha nawufaka i-RTD eneentambo ezimbili, amatheminali wokuvikela 4 no-2 kufanele abe isekhethi emfitjhani
