LCD display.Positioner boot-time of 0.5 second.Operates normally with sudden changes in supply pressure, vibration.Remote positioner is stronger on high temperature and vibration environment.Separate remote sensor and positioner.
For Operation Of Pneumatic Valve Actuators:
Simple zero and span adjustment.
No resonance between 5-200Hz.
Auto/Manual switch.
RA v.s. DA action and 1/2 split range setting by simple adjustment.
Internal feedback signal is available as an option (weather proof only).
2 million life cycle guaranteed.
Response time is very fast and accurate.
Simple part change can set 1/2 split range.
Low air consumption.
Simple Direct / Reverse Action change.
Simple Zero & Span adjustment.
Easy feedback connection.
Operates normally in extreme environment (vibration & temperature):Durability tested 2 million cycles at the minimum.Short and accurate response time.Simple part change can set 1/2 Split Range.Economical due to less air-consumption.
