Ukuhlolisisa

I-thermocouple input isolation safety barrier ingadlulisa isignali ye-millivolt ukusuka ku-thermocouple (TC) endaweni eyingozi ukuya endaweni ephephileko ngo-1: 1.

Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, okuphakelwa kwamandla okuhlukileko, ukungena, nokukhipha amatheminali.

"*" imelela umhlobo wokufaka we-thermocouple, begodu imodeli ethileko imelelwa yikhodi (qala "Umhlobo weSiginali yokufaka kanye nethebula lebanga" ukuthola imininingwana).

Iinqophiso

Ukufaka endaweni eyingozi
Isiginali yokufaka	K, S, E, J, B, T, R, N amatshwayo we-thermocouple (qala "Umhlobo weSignali yokufaka kanye nethebula lebanga" ukuthola imininingwana)
Ibanga lesiginali	-20~80mV.
Umphumela wehlangothi lokuphepha:
Isiginali yokuphuma	I-Thermocouple 1: 1
Isitjengiso se-LED	Okuluhlaza: Inkomba yamandla
Ukunemba kokuphuma	0.05%FS
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	Phakathi kwehlangothi eliphephileko nelingaphephileko (≥ 3000VAC/min); hlangana nokuphakelwa kwamandla netheminali engaphephiko (≥ 1500VAC/min)
Ukujamelana nokuvikela	≥100MΩ (phakathi kokufaka/ukukhipha/ukuphakelwa kwamandla)
Ukukhambisana kwe-elekthromagnethi	Ngokuya nge-IEC 61326-1(GB/T 18268), i-IEC 61326-3-1
MTBF	100000h
Iimfuneko zeentambo	Isigaba esiphambanweni ≥ 0.5mm2; Amandla wokuvikela ≥ 500V
Iinsetjenziswa ezisebenzako	K. S, E, J, B, T, R, N TC izinzwa
Indawo yokufaka	Ifakwe endaweni ephephileko, ingahlanganiswa namathulusi wokuphepha wangaphakathi eendaweni eziyingozi ukuya ku-Zone 0, IIC, Zone 20, kanye ne-IIIC

Ubukhulu

Umdwebo ohlelekileko

Tjheja:

1. Umsebenzi we-power rail ngumsebenzi ongakhetha kiwo, begodu abasebenzisi kufuze bacacise indlela yokunikela amandla lokha nabenza i-oda

Ukukhethwa kwezixhumanisi zesitimela samandla kungabhekisa ekhasini 89 le "Isithasiselo"
