Hordhac ku saabsan Wax soo saarka 4-20 mA

1. Waa maxay wax soo saarka 4-20 mA
4-20 mA waa calaamad caadi ah oo hadda ah oo analog ah oo si weyn loogu isticmaalo qalabka warshadaha, sida mitirrada heerka, mitirrada socodka, gudbiyeyaasha cadaadiska, iwm.
4 mA waxay u taagan tahay qiimaha 0% ee hoose ee kala duwanaanshaha
20 mA waxay u taagan tahay qiimaha 100% ee heerka sare
2. Faa'iidooyinka 4-20 mA
Awood xooggan oo ka hortagga faragelinta, oo ku habboon gudbinta masaafada fog
Wax saameyn ah kuma yeelan karaan iska caabbinta fiilada iyo hoos u dhaca danabka
Si fudud ayaa loo ogaan karaa jabka siligga (calaamad < 4 mA macnaheedu waa cillad)
La jaan qaadaya inta badan PLC-yada, DCS, duubayaasha iyo nidaamyada xakamaynta
Xasilloon oo lagu kalsoonaan karo jawi warshadeed oo adag
3. Codsiyada caadiga ah
Gudbi qiimayaasha la cabbiray (heerka, socodka, cadaadiska, heerkulka)
Ku xidh nidaamyada xakamaynta si aad ula socoto oo aad u xakamayso
Waxaa loo isticmaalaa qalab kala duwan oo warshadaha ah
Ku habboon saliidda, daaweynta biyaha, kiimikada, korontada iyo warshadaha kale
