Pneumatic Positioners

Pneumatic Positioner - SDPP 1200R

Pneumatic positioner is a useful interlinking device controlling cylinder/valve movement in proportion to pneumatic signal ranging between 0.2 to 1 bar (3 to 15 psi) or split ranges. The salient features of Schrader Pneumatic Positioner are:

  • It is compact.
  • Works effectively under adverse environmental conditions
  • It is economical due to minimal air consumption.
  • Provision of orifice-disc to prevent hunting in small size actuators.
  • Convenient changeover from single acting to double acting and vice versa.

Smart Positioner - SDSP 2300 R

Smart Positioner controls the stroke of the actuator in proportion to the input signal between 4-20mA. Besides, an efficient built-in microprocessor performs functions like auto calibration, PID control, Alarm and Hart protocol etc. In addition,

  • LCD display unit communicates the status of the actuator unit.
  • Hart communicator processes the variety of information related to actuator & positioner.
  • PID parameters can be easily adjusted in the field without using communicator.
  • Positioner transmitter is also offered as an optional accessory.
