Abstract: A device and method for measuring the rotational position of a rotating feature, the device employing rotary to linear magnification. A connecting member is operatively connected to the rotating feature, the connecting member extending through one or more structural layers of an enclosure. An arm is operatively connected to the connecting member and located outside the enclosure. A target is arranged with respect to a position sensor, with the position sensor configured to measure the linear position of the target with respect to the position sensor. A cable is connected to the arm at an attachment point, the cable also being connected to the target. One or more pulleys are arranged to control the path of the cable between the attachment point on the arm and the target.

Abstract: A sensor assembly includes a first structure and a second structure disposed radially outwardly of the first structure. Also included is a sensor body extending through the first and second structures, the sensor body having first and second ends, the first end disposed proximate a first environment defined by the first structure and the second end located radially outwardly of the second structure. Further included is a first sealing assembly configured to operatively couple the sensor body to the second structure and to accommodate movement of the sensor body. Yet further included is a position sensor operatively coupled to the sensor body, the position sensor configured to determine a position of a target located within the first interior volume. Also included is at least one biasing member in contact with the target to bias the target into constant operative contact with the sensor body.

Abstract: A sensor assembly includes a first structure and a second structure disposed radially outwardly of the first structure. Also included is a sensor body extending through the first and second structures, the sensor body having first and second ends, the second end disposed in an ambient environment. Further included is a first sealing assembly configured to couple the sensor body to the second structure and to accommodate movement of the sensor body due to relative movement between the first and second structures. Yet further included is an interior cavity defined by an interior wall of the sensor body and a rotary position sensor mounted to the sensor body proximate the second end of the sensor body, the rotary position sensor configured to detect an angular position of a target disposed within the first environment, the rotary position sensor coupled to the target with a sensor linkage assembly.
