Smart Positioners

The Smart Positioner Series 8400S is a Smart two-wire device that uses a 4-20mA signal input as its set point, deriving its power from the same. It compares the set point with the actual position of the Actuator stem and eliminates the positioning error accurately using an internal PID control action.

Positioners

Positioners use  feedback information to ensure that actuator is in the correct position. Can assist in overcoming friction and greater actuating pressures are available. Works on principle of "Pressure Balance". Rugged construction. Amplify pressure to the actuator. Allows characterisation either mechanically (by feedback cam) or electronically (smart positioner). Negates variable process reaction pressure effect on position. Allows split ranging.
