Isithumeli sokushisa sokufaka i-RTD singahlukanisa futhi siguqule isignali ye-thermal resistor (RTD) ibe isignali ye-DC, esetshenziselwa ukushayela umthwalo. Ukucushwa okuhlakaniphile kungenzeka, futhi ububanzi bangempela bokumelana nokushisa bungasethwa ngesofthiwe yekhompyutha. Inomsebenzi we-alamu yokuxhuma kanye nomsebenzi we-alamu ongaphandle kwebanga.
Lo mkhiqizo udinga ukunikezwa amandla ngokuzimela, futhi amatheminali okunikezwa kwamandla, okokufaka kanye nokukhiphayo ahlukaniswe.
| Okokufaka | |
| Isignali yokufaka | Izimpawu ezimbili ze-thermistor yezintambo noma ezintathu (bheka "Uhlobo Lwesignali Yokufaka kanye Nethebula Lobubanzi" ukuthola imininingwane) |
| Ukunqanyulwa kokufaka | "I-alamu ephansi" ezenzakalelayo ingashintshwa ibe "i-alamu ephezulu" ngesofthiwe yokucushwa |
| Ibanga lesiginali | Ububanzi bokulinganisa obuhambisanayo bokumelana nokushisa |
| Ububanzi bokulinganisa | Abasebenzisi benza ukucushwa kwabo lapho be-oda, futhi bakubonise ngenombolo yomsila noma ngenye indlela. |
| Ugesi wokuvuselela | 800μA |
| Umphumela: | |
| Isignali yokuphuma | Isignali ye-DC (yamanje/i-voltage) |
| Umthamo womthwalo | Ukumelana nomthwalo wamanje ≤500Ω (kungenziwa ngezifiso) Ukumelana nomthwalo we-voltage
|
| Amapharamitha ayisisekelo: | |
| I-voltage yokunikezela | 20-35VDC |
| Ukusetshenziswa kwamandla | Ukuphuma kwamanje |
| Isikhombisi se-LED | Okuluhlaza: Isikhombisi samandla isibani esiphuzi se-alamu yebanga eliphansi sivuliwe, isibani esibomvu se-alamu yebanga eliphezulu sivuliwe |
| Ukunemba kokukhipha | Sicela ubheke "Uhlobo Lwesignali Yokufaka kanye Nethebula Lobubanzi" ukuthola imininingwane |
| Isikhathi sokuphendula | Kufinyelelwa ku-90% wenani lokugcina ngaphakathi kwama-300ms |
| Ukukhukhuleka kwezinga lokushisa | 0.005%FS/℃ |
| Amapharamitha okushisa | Izinga lokushisa lokusebenza: -20℃~+60℃, izinga lokushisa lokugcina:-40℃~+80℃ |
| Umswakama ohlobene | 10%~95% RH akukho ukujiya |
| Amandla e-dielectric | ≥2000VAC/min (phakathi kokufaka/ukukhipha/ukunikezwa kwamandla) |
| Ukumelana nokushisa | 100MΩ(500VDC)(phakathi kokufaka/ukukhipha/ukunikezwa kwamandla) |
| Ukuhambisana kwe-electromagnetic | GB/T 18268(IEC 61326-1) |
| I-MTBF | 800000h |
| Izidingo zentambo | Isigaba esiphambeneyo ≥ 0.5mm²; Amandla okuvikela ≥ 500V |
| Imishini yasensimini esebenzayo | Ama-thermistors amabili noma amathathu e-wire G53, Cu50, Pt100, Pt1000, Ni1000 |
Qaphela: 1. Umsebenzi wesitimela samandla ngumsebenzi ongawukhetha, futhi abasebenzisi kudingeka bacacise indlela yokunikezwa kwamandla lapho befaka i-oda. Ukukhethwa kwezixhumi zesitimela samandla kungabhekisela ekhasini 89 le-"Annex" 2. Uma ufaka i-RTD yezintambo ezintathu, kubalulekile ukuqinisekisa ukuthi izintambo ezintathu zilingana ngobude ngangokunokwenzeka. 3. Uma ufaka i-RTD yezintambo ezimbili, amatheminali okuvimbela ukuphepha 5 no-6(2 no-3) kumele afinyezwe.
