Isithiyo sokuphepha sokuhlukanisa sokufakwa kwe-thermistor esinomsebenzi wokuvikela ukukhuphuka singaguqula amasiginali we-Pt100 wezintambo ezimbili nezifudumezi zezintambo ezintathu (ama-RTD) ezindaweni eziyingozi zibe isignali engu-1:1 ye-thermistor futhi iyidlulisele endaweni yokuphepha. Ingacushwa ngobuhlakani, futhi ububanzi bangempela bokumelana nokushisa bungasethwa ngesofthiwe yekhompyutha. Inemisebenzi ye-alamu yokuphuka kocingo kanye ne-alamu ephuma ebangeni.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okunokunikezwa kwamandla okukodwa, okokufaka, namatheminali aphumayo.

Ubukhulu
Imidwebo Ehlelekile
Qaphela:
1. Umsebenzi wesitimela samandla uwumsebenzi ozikhethela wona, futhi abasebenzisi badinga ukucacisa indlela yokuphakelwa kwamandla lapho befaka i-oda.
Ukukhethwa kwezixhumi zikaloliwe wamandla kungabhekisela ekhasini 89 le-"Annex"
2. Lapho ufaka i-RTD yocingo emithathu, kuyadingeka ukuqinisekisa ukuthi izintambo ezintathu zinobude obulinganayo ngangokunokwenzeka.
3. Uma ufaka i-RTD enezintambo ezimbili, amatheminali okuvimbela ukuphepha 5 kanye no-6 kufanele abe nesekhethi emfishane.
