P3300i Series Electro/Pneumatic Valve Positioners
INTRODUCTION
The P3300i valve positioner series is an electric signal adaptation of the P3300 pneumatic valve positioner. It incorporates all the capabilities of the P3300 while being compatible with a standard 4-20 mA signal for operation.
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.
Input Signal
  • 4-20 mA dc + split range.
