Abstract
A wireless pressure sensor comprising a protective covering positionable over the sensor's antenna portion is described. The protective covering comprises a body having an annular sidewall that extends from a proximal end to a distal end and is composed of a fluoroelastomer material. A cavity resides within the body extending through the proximal end to a distal end sidewall positioned perpendicular to the annular sidewall. The protective covering further comprises at least one annular recess intermediate at least two annular ridges that reside along an interior surface at the proximal end of the covering. These series of annular ridges and recesses form a removably tight seal around the exterior surface of the sensor that minimizes the migration of corrosive gases and fluids to the exterior surface of the sensor.
