Ukubuka konke
Isithiyo sokuphepha sokufakwa kwe-thermistor esinomsebenzi wokuvikela ukukhuphuka singaguqula izimpawu ze-Pt100 zama-thermistors amabili ezintambo kanye nama-thermistors amathathu ezintambo (ama-RTD) ezindaweni eziyingozi zibe yisignali engu-1:1 ye-thermistor bese siyidlulisela endaweni yokuphepha. Ingalungiswa ngobuhlakani, futhi ububanzi bangempela bokumelana nokushisa bungabekwa ngesofthiwe yekhompyutha. Inemisebenzi ye-alamu yokuphuka kwezintambo kanye ne-alamu engaphandle kwebanga. Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okuneziphesheli zamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.

| I-MTBF | 800000h |
| Izidingo zentambo | Ingxenye ephambene ≥ 0.5mm2; Amandla okuvikela ≥ 500V |
| Imishini yasensimini esebenzayo | Izintambo ezimbili noma ezintathu ze-RTD Pt100 |
Qaphela: 1. Umsebenzi wesitimela samandla ngumsebenzi ongawukhetha, futhi abasebenzisi kudingeka bacacise
indlela yokunikezwa kwamandla lapho ubeka i-oda
Ukukhethwa kwezixhumi zesitimela sikagesi kungabhekisela ekhasini 89 le-"Annex"
2. Uma ufaka i-RTD yezintambo ezintathu, kubalulekile ukuqinisekisa ukuthi ezintathu
izintambo zilingana ngobude ngangokunokwenzeka
3. Uma ufaka i-RTD enezintambo ezimbili, amatheminali okuvikela ukuphepha 6 no-5 kumele abe
i-short circuits
