1.4 Principles of Operation
1.4.1 Enclosures
The ICoT PA Positioner can be built in three different enclosure materials: engineered
resin, 316 stainless steel and aluminum.
1.4.2 Position Feedback
Non-Contact Position Feedback
To provide consistently accurate performance information, all linkages, levers and
connecting rods, from the positioner to the control valve have been eliminated from
the design. Valve position sensing is performed totally by non-contacting means
based upon characterization of magnetic flux strength as a function of position.
