Claim:
1. A sensor assembly comprising: a first structure defining a first interior volume having a first environment with a first temperature and a first pressure; a second structure disposed radially outwardly of the first structure and defining a second interior volume having a second environment with a second temperature and a second pressure each lower than the first temperature and the first pressure; a sensor body extending through a first aperture of the first structure and a second aperture of the second structure, the sensor body having a first end and a second end, the first end disposed within the first environment and the second end disposed in an ambient environment located radially outwardly of the second structure, wherein the ambient environment has an ambient temperature and an ambient pressure each lower than the second temperature and the second pressure; a first sealing assembly configured to operatively couple the sensor body to the second structure and to accommodate movement of the sensor body due to relative movement between the first structure and the second structure; 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 operatively coupled to the target with a sensor linkage assembly located within the interior cavity of the sensor body.
