Ukuhlolisisa
I-RTD yokufaka izinga lokutjhisa ingahlukanisa begodu itjhugulule isiginali yokujamelana nokutjhisa (RTD) ibe siginali ye-DC, esetjenziselwa ukutjhayela umthwalo. Ukuhleleka okuhlakaniphileko kungenzeka, begodu ububanzi bamambala bokujamelana nokutjhisa bungasethwa ngesofthiwe yekhomphyutha. Inomsebenzi we-alamu yokuvala kanye nomsebenzi we-alamu engaphandle kwebanga.
Umkhiqizo lo udinga ukunikelwa amandla ngokuzijamela, begodu ukunikelwa kwamandla, ukungena nokukhipha amatheminali ahlukaniswe.
| Faka | |
| Isiginali yokufaka | Amatshwayo we-thermistor yeentambo ezimbili nofana ezintathu (qala "Umhlobo weSiginali yokufaka kanye nethebula lebanga" ukuthola imininingwana) |
| Ukuvalwa kokufaka | "I-alamu ephasi" engatjhugululwa ibe "yi-alamu ephezulu" ngesofthiwe yokuhlela |
| Ibanga lesiginali | Ububanzi bokulinganisa obuhambisanako bokujamelana nokutjhisa |
| Ibanga lokulinganisa | Abasebenzisi benza ukuhlelwa kwabo lokha naba-oda, begodu bakutjengise kunomboro yomsila nofana ngenye indlela. |
| Ukuthaba kwamanje | 800μA |
| Umphumela: | |
| Isiginali yokuphuma | Isiginali ye-DC (yamanje/ivoltheji) |
| Umthamo wokuthwala | Ukujamelana nomthwalo wamanje ≤500Ω (okungenziwa ngokwezifiso) Ukujamelana nomthwalo wevoltheji
|
| Amapharamitha asisekelo: | |
| Ivoltheji yokuphakela | 20-35VDC |
| Ukusetjenziswa kwamandla | Ukukhiqizwa kwamanje |
| Isitjengiso se-LED | Okuluhlaza: Isitjengiso samandla se-alamu yebanga eliphasi ikhanyisa etjheli, i-alamu yebanga eliphezulu ikhanya elibomvu ivuliwe |
| Ukunemba kokuphuma | Sibawa uqale "Uhlobo lwesiginali yokufaka kanye nethebula lebanga" ukuthola imininingwana |
| Isikhathi sokuphendula | Ukufikelela ku-90% wenani lokugcina ngaphakathi kwama-300ms |
| Ukutjhuguluka kwamazinga womtjhiso | 0.005%FS/°C |
| Amapharamitha womtjhiso | Izinga lokutjhisa lokusebenza: -20°C~+60°C, izinga lokutjhisa lokugcina:-40°C~+80°C |
| Umswakama ohlobene | 10%~95% RH akukho ukutjhisa |
| Amandla we-dielectric | ≥2000VAC/min (phakathi kokufaka/ukukhipha/ukuphakelwa kwamandla) |
| Ukujamelana nokuvikela | 100MΩ(500VDC )(phakathi kokufaka/ukuphuma/ukuphakelwa kwamandla) |
| Ukukhambisana kwe-elekthromagnethi | GB/T 18268(IEC 61326-1) |
| MTBF | 800000h |
| Iimfuneko zeentambo | Isigaba esiphambanweni ≥ 0.5mm2; Amandla wokuvikela ≥ 500V |
| Iinsetjenziswa ezisebenzako | Iintambo ezimbili nofana ezintathu thermistors G53, Cu50, Pt100, Pt1000, Ni1000 |
Qaphela: 1. Umsebenzi we-power rail ngumsebenzi ongakhetha kiwo, begodu abasebenzisi kufuze bacacise indlela yokuphakelwa kwamandla lokha nabenza i-oda. Ukukhetha iinhlanganisela ze-power rail kungabhekisa ekhasini 89 le-"Annex" 2. Lokha nakufakwa i-RTD yeentambo ezintathu, kuyatlhogeka bona uqinisekise bona iintambo ezintathu zinobude obulinganako ngendlela ekungakghoneka ngayo Lokha nakufakwa i-RTD emibili, kuvikeleka. amatheminali we-barrier 5 no-6(2 no-3) kufanele abe mfitjhani

| Ikhodi | Imodeli ye-RTD | Ibanga lokulinganisa | Ibanga eliphasi | Ukunemba kokutjhugulula |
| 1 | G53 | -50～150°C | 20°C | 0.2°C/0.1% |
