With Feedback Signals Now Being Electrical Rather Than Mechanical, The Positioner Is No Longer Required To Be Mounted On The Valve.Advantageous For Extreme Vibration and Temperature

Various Length Triggers Systems 0.300” to 48.0 inch Strokes.No Troublesome Rotary / Linear Conversion Linkage Kits.



No Linkage to wear, or misalignmentIncreased Accuracy and reliability of Feedback



Linear TypeRotary Type

• Ease of maintenance Only two components:• Electronic Canister• IP Transducer.• Min. spare parts required • Allows future upgrades



Non-Contact Positioning.Remote Mounting Ability.Electronic Speed Control.Push Button Calibration for Speed & Accuracy.Linear & Rotary Applications From One Positioner Package.


ICoT-PositionerICoT-PositionerFeatures:

Increased Accuracy and Sensitivity (Minimal Hysteresis)Speed Of Response, Speed Control. Tighter Control Of Process Loop. Quality Of Process Output

Increased.Reliability Increase. Lower Down Time For Maintenance

& Re-Calibration.


ICoT-PositionerICoT-PositionerProcess Benefits:

Handheld communicatorFull Calibration of Positioner from any point on the loop, at the Instrument or I/O Card.
