Apparatus for isolating a sensor

摘要

Apparatus is provided for isolating a sensor from a vibrating surface. The sensor has first and second spaced surfaces, a bore extending between the surfaces and a groove in the second surface. The apparatus includes a flanged sleeve adapted to extend through the bore to the vibrating surface. The sleeve is sufficiently long when extending through the bore to provide a first gap between the vibrating surface and the second surface of the sensor and sufficiently narrow when extending through the bore to provide a second gap between the sleeve and the sensor. The flange overlays the first surface of the sensor and the second gap. The apparatus also includes a bolt, which extends through the bore and into engagement with the vibrating surface, for attaching the sleeve to the vibrating surface. The apparatus also includes a first O-ring positioned between the first surface of the sensor and the sleeve flange and a second O-ring positioned in the groove of the second surface. The first O-ring spaces the sensor from the sleeve and the flange and the second O-ring is adapted to abut the vibrating surface and space the sensor from the vibrating surface and the sleeve, such that the sensor floats between the first and second O-rings in isolation from the sleeve and the vibrating surface.
