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.

A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
