New SITRANS VP300 intelligent valve positioners incorporate 2007 Nobel Price winning Giant Magneto Resistance effect.
They also feature SIL-certified partial stroke testing for linear and rotary actuators to ensure emergency shutdown valves are movable during an emergency.
The GMR technology is used for noncontact position sensing of a linear or rotary valve shaft. This eliminates any mechanical wear or complex interaction of couplings and levers between components. VP300 requires only a single magnet for strokes to 150 mm / 5.9-in. or rotary angles up to 120°.
With GMR technology this positioner is less sensitive to vibration with accuracy and less wear benefits.
SITRANS VP300 features an aluminum housing with high IP66/NEMA 4X protection. It’s applicable over -40° to +85°C. Full positioners details are yours free.
