Pneuamatic Positioner

P3300i Series Electro/Pneumatic Valve Positioners

INTRODUCTION
The P3300i series of valve positioners is a milliampere signal version of the P3300 pneumatic valve positioner. It utilises all the features of the P3300 but can operate from a standard 4-20 mA signal.

CONSTRUCTION

  • Case :
    Epoxy painted Aluminium as standard. Optional Stainless Steel.
  • Covers :
    Polyester/Aluminium (Epoxy painted). Optional Stainless Steel.
  • Internals :
    Brass/Steel/Aluminium. Optional all Stainless Steel.

The case/cover of the positioner are of rugged construction. The positioner is mounted on a heavy duty plate which affords very good resistance to rough handling and vibration.

ADJUSTMENTS

  • Zero and span adjustments on the I/P module are easily accessible and are non-interactive.
