Description
The electrical position transmitters SMI983 and SRD960-TXQ convert the linear or rotary movement of a valve / actuator into a 4 to 20 mA standard electrical signal (Two-wire circuit). The configuration of the feedback signal in correspondence to the position of the actuator is easily performed by two push-buttons.
Benefits
Wear free, highly linear scanning with conductive plastic precision potentiometer
Specially suitable for small strokes by using a movement amplification mechanism
Easy adjustment of zero and span with two Push Buttons and two LEDs
For linear and rotary movement
Easy configuration of the feedback from direct to reverse
Intrinsically Safe (with the SMI983) or Explosion Proof (with the SRD960-TXQ)
Applications
For on/off or control valves
Can be used in addition of a Valve Positioner to provide valve feedback position
All process industries applications with or without electrical certification
