Ukubuka konke
Isithiyo sokuphepha sokufakwa kwe-thermistor singaguqula izimpawu ze-Pt100 zama-thermistors amabili ezintambo kanye nama-thermistors amathathu ezintambo (ama-RTD) ezindaweni eziyingozi zibe umphumela owodwa onesignali ye-RTD engu-1:1 kanye nomphumela owodwa onesignali engu-4~20mA endaweni yokuphepha. Ingalungiswa ngokuhlakanipha, futhi ububanzi bangempela bokumelana nokushisa bungabekwa ngesofthiwe yekhompyutha.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okuneziphesheli zamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.
| Imininingwane | |
| Okokufaka endaweni eyingozi | |
| Isignali yokufaka | Isignali ye-RTD Pt100 enezintambo ezimbili noma ezintathu |
| Ububanzi bokulinganisa | -200℃ -850℃ |
| Umphumela ohlangothini lokuphepha: | |
| Isignali yokuphuma | Isiginali ye-RTD Pt100 kanye nesiginali engu-4 ~ 20mA |
| Umthamo womthwalo | Umthamo womthwalo 0-500 Ω (kungenziwa ngezifiso) |
| I-voltage yokunikezela | 20-35VDC |
| Ukusetshenziswa kwamandla | ≤76mA (uma ugesi ongu-24VDC unikezwa, umphumela ongu-20mA) |
| Isikhombisi se-LED | Okuluhlaza: Isikhombisi samandla |
| Ukunemba kokukhipha | 0.1%FS |
| Ukukhukhuleka kwezinga lokushisa | 0.1%FS/10℃ |
| Amapharamitha okushisa | Izinga lokushisa lokusebenza: -20℃~+60℃, izinga lokushisa lokugcina:-40℃~+80℃ |
| Umswakama ohlobene | 10%~95% RH akukho ukujiya |
| Amandla e-dielectric | Phakathi kohlangothi oluphephile ngokwemvelo kanye nohlangothi oluphephile ngokwemvelo (≥ 3000VAC/min); |
| phakathi kokunikezwa kwamandla kanye netheminali engaphephile ngokuphelele (≥ 1500VAC/min) | |
| Ukumelana nokushisa | ≥100MΩ (phakathi kokufaka/ukukhipha/ukunikezwa kwamandla) |
| Ukuhambisana kwe-electromagnetic | Ngokusho kwe-IEC 61326-1(GB/T 18268), i-IEC 61326-3-1 |
| I-MTBF | Amahora angu-100000 |
| Izidingo zentambo | Ingxenye ephambene ≥ 0.5mm2; Amandla okuvikela ≥ 500V |
| Imishini yasensimini esebenzayo | Izintambo ezimbili noma ezintathu ze-RTD Pt100 |
| Indawo yokufaka | Uma ifakwe endaweni ephephile, ingaxhunywa kumathuluzi okuphepha angaphakathi ezindaweni eziyingozi kuze kufike ku-Zone 0, IIC, Zone 20, kanye ne-IIIC. |
| Isitifiketi sokuphepha | |
| Uphawu lobufakazi bokuqhuma | [Ex ia Ga]lIC [Ex ia Da]lllC |
| Izinga elivikela ukuqhuma | GB/T3836.1-2021 GB/T3836.4-2021 |
| Amatheminali 4-6,5-6 | Um:250V AC/DC Uo=8.4V DC lo=31mA |
| I-Po=65.1mW Co=4.8μF Lo=20mH | |
| Umzimba wesitifiketi | I-CQST (Isikhungo Sikazwelonke Sokuqapha Ikhwalithi kanye Nokuhlola Imikhiqizo Kagesi Evikelwe Ukuqhuma) |
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
