TECHNICAL DATA:

• Non-reactive conversion of valve- or actuator-position into a load-independent 4 to 20 mA signal
• Two-wire circuit

COMMON FEATURES:

• Easy adjustment of zero and span by two push buttons
• Operating condition is displayed by two LEDs
• Easy configuration of the feedback from direct to reverse
• The feedback signal can be randomly adjusted between 4 to 20 mA
• Wear-free, high linear scanning with conductive plastic precision potentiometer
• Mounting on linear actuators according to IEC 534, Part 6 (NAMUR)
• Mounting on rotary actuators according to VDI/VDE 3845
• Simple adjustment to strokes of 5 to 100 mm (0.3 to 4 in) and, by means of rotary adapter, to angular displacements of up to 120°
• Protection class IP 54,
  IP 65 (on request)
• Explosion protection:
  • II 2 G EEx ia IIC acc. to ATEX
  • “Intrinsic Safety” acc. to FM and CSA

The electrical position transmitter SMI983 converts the linear or rotary movement of a valve / actuator into a 4 to 20 mA standard electrical signal.
   The configuration of the feedback signal in correspondence to the position of the actuator is easily performed by two push-buttons.
