Реферат: A position transfer device is configured for use on a control valve for converting 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. A valve positioner or controller can process the signal to identify the position of the closure member relative to a seat. In one implementation, the position transfer device includes a shaft that clamps onto a pin. This arrangement causes the pin to translate radially about an axis that is perpendicular to the shaft. The magnets move in response to the pin. This provides a more robust mechanism that is less susceptible to outside influences like vibrations.
