LYR jerin thermocouple zafin jiki mai watsawa ne canza shigarwa thermocouple siginar ta hanyar layi gyara keɓewa zuwa misali DC halin yanzu siginar ko DC ƙarfin lantarki siginar da ake bukata da mai amfani, da kuma wutar lantarki, shigarwa, fitarwa uku keɓewa juna.

A. LYR jerin thermocouple siginar keɓe aiki da kuma aiki ka'idar:

Ka'idar aikin siginar thermocouple ta dogara ne akan tasirin thermoelectric, wato, ƙarfin lantarki da aka samar a ƙarƙashin yanayin zafi ta amfani da kayan daban-daban gudanarwa ko semiconductors. Girman wannan ƙarfin lantarki yana da alaƙa da kayan mai gudanarwa ko semiconductor da bambancin zafin jiki tsakanin su. Thermocouple zafin jiki keɓewa mai watsawa amfani da wannan ka'ida don sarrafawa da canza siginar lantarki daga filin thermocouple fitarwa don biyan bukatun filin masana'antu. ‌

biyuMain fasaha nuna alama:

1, fitarwa kaya: ≤550Ω a lokacin 4-20mA, ƙarfin lantarki irin ≥250KΩ

2, tushe kuskure: ± 0.5% FS3, wutar lantarki: 24VDC ± 10%

4, zafin jiki yawo: ≤0.01% FS / ℃

5, karfafa juriya: ≥100MQ / 500VDC tsakanin ikon-shigarwa-fitarwa

6, rufi ƙarfi: 1000VAC / min

7, ikon amfani: daya a cikin daya fitawa <1.4w, daya a cikin biyu fitawa <2w biyu a cikin biyu fitawa <2.8W

8, aiki yanayi: yanayin zafin jiki 0 ~ 50 ℃

Relative zafi ≤85% RH (kauce wa karfi lalata gas) 9, Shigarwa hanya: bayan kwamfuta katin shigarwa (DIN35 Track)
