Abstract

A position transfer device is configured for use on a control valve. These configurations may convert a linear position of a closure member on the control valve to an angular position of magnets. A sensor in proximity to the magnets can generate a signal in response to the angular position. In one implementation, a valve positioner or controller can process the signal to identify the position of the closure member relative to a seat.
