Isingeniso ku-4-20 mA Output

1. Kuyini ukuphuma kwe-4-20 mA
I-4-20 mA iyisignali yamanje ye-analog ejwayelekile esetshenziswa kabanzi kumathuluzi ezimboni, njengemitha yamazinga, amamitha okugeleza, ama-pressure transmitters, njll.
I-4 mA imele inani eliphansi elingu-0%
I-20 mA imelela inani lebanga eliphezulu elingu-100%
2. Izinzuzo ze-4-20 mA
Amandla aqinile okulwa nokuphazamiseka, afanelekela ukudluliselwa ibanga elide
Akuthinteki kakhulu ukumelana kwekhebula kanye nokwehla kwamandla kagesi
Kulula ukubona ukuphuka kwentambo (isignali < 4 mA isho iphutha)
Iyahambisana nama-PLC amaningi, ama-DCS, ama-recorder kanye nezinhlelo zokulawula
Izinzile futhi ithembekile ezindaweni zezimboni ezinzima
3. Izinhlelo zokusebenza ezijwayelekile
Dlulisa amanani alinganisiwe (izinga, ukugeleza, ingcindezi, izinga lokushisa)
Xhuma ezinhlelweni zokulawula ukuze uqaphe futhi ulawule
Kusetshenziswa ezinsimbini ezahlukene zensimu yezimboni
Ifaneleka ku-oyela, ukwelashwa kwamanzi, amakhemikhali, ugesi kanye neminye imboni
