Features

  • The positioner provides accurate, fast response and can withstand the vibrations of most plant environments.
  • With the cover removed, zero span and cross-over adjustments are easily accessible and can be made with a screw driver.
  • Easily adjustable minor loop gain fine tunes the positioner to optimize dynamic response for each specific actuator size and application.
  • Changes in supply pressure have minimal effect on positioner operation.
  • Case, components, and gasket materials withstand harsh environments. Positioner bleed air purges internal parts and actuator housing for additional protection.
  • Simple adjustments permit switching between direct and reverse action; no additional parts are required.
