SENSOR ASSEMBLY AND METHOD OF DETECTING POSITION OF A TARGET THROUGH MULTIPLE STRUCTURES

摘要

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 sensor mounted to the sensor body proximate the second end, the sensor configured to detect a characteristic of a target disposed within the first structure. Yet 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. The first sealing assembly includes a mounting body, a radial seal, a slider plate and a slider plate retainer disposed in a recess of the mounting body and in abutment with the slider plate.

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 sensor mounted to the sensor body proximate the second end of the sensor body, the sensor configured to detect at least one characteristic of a target disposed within the first environment; and 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, the first sealing assembly comprising:
a mounting body coupled to the second structure;a radial seal disposed in a groove of the sensor body;a slider plate having a cylindrical portion and a ring portion, the cylindrical portion and the ring portion disposed substantially orthogonal to each other, the cylindrical portion disposed in abutment with the radial seal; anda slider plate retainer disposed in a recess of the mounting body and in abutment with the ring portion of the slider plate to fix the slider plate.
