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: I-Isolated safety barrier Pt100 input, ibanga lokutjhisa 0~400°C, imiphumela emibili ine-4~20mA, umthombo wamandla ngu-20~35VDC. Imodeli yi-PHD-22TZ-4141(0~400°C), ibanga lokulinganisa lingasethwa libe libanga elibekiweko le-0~400°C ngekhomphyutha.
* Ukuphakelwa kwamandla wetheminali yebhasi, sibawa uqale isithasiselo ukuthola imininingwana.
| Iinqophiso | |
| Faka ngaphakathieyingoziisifunda | |

2. Lokha nawufaka i-RTD yeentambo ezintathu, kuyatlhogeka bona uqinisekise bona iintambo ezintathu iintambo zinobude obulinganako ngendlela ekungakghoneka ngayo
3. Lokha nawufaka i-RTD eneentambo ezimbili, amatheminali wokuvikela 5 no-6(2 no-3) kufanele kube mfitjhani
