Nhanganyaya ye4-20 mA Output

1. Chii chinonzi 4-20 mA output
4-20 mA chiratidzo chemazuva ano cheanalog chinoshandiswa zvakanyanya mumidziyo yeindasitiri, senge level metres, flow metres, pressure transmitters, nezvimwewo.
4 mA inomiririra kukosha kwenzvimbo yakaderera ne0%
20 mA inomiririra kukosha kwe100% kwepamusoro
2. Mabhenefiti e4-20 mA
Kugona kwakasimba kwekudzivirira kupindira, kwakakodzera kutapurirana kure
Zvishoma zvinokanganiswa nekuramba kwetambo uye kudonha kwemagetsi
Zviri nyore kuona kuputika kwewaya (chiratidzo < 4 mA zvinoreva kukanganisa)
Inoenderana nemaPLC mazhinji, DCS, marekodhi uye masisitimu ekudzora
Yakagadzikana uye yakavimbika munzvimbo dzakaoma dzemaindasitiri
3. Mashandisirwo akajairika
Tumira zviyero zvakayerwa (danho, kuyerera, kumanikidzwa, tembiricha)
Batanidza kune masisitimu ekudzora kuti utarise uye utonge
Inoshandiswa mumidziyo yakasiyana-siyana yemumaindasitiri
Yakakodzera mafuta, kurapwa nemvura, makemikari, magetsi nezvimwe zvinhu
