why to use 3 wire at RTD ?
what's the reason for
common wire ?
Answer Posted / rathod mukesh r
If 2 Wire rtd use , The distance is more between remote location (Rtd) And dcs panle then error occur in reading of temperature. Means if wire length is increases then its own resistance also increase so proper reading is not transmited via 2 Wire. In 3 Wire rtd these error is remove using compensasion lead.
