Abstract
A positioner for a control valve assembly is disclosed wherein the positioner is mounted internally to thus protect the positioner from damage stemming from environmental, impact, or other outside influences. Accordingly, not only can the position of the valve be accurately measured, but the sensing hardware is less subjected to damage or other drawbacks associated with exposure.
