Sensor and housing suitable for harsh environments

Abstract

A sensor and housing suitable for harsh environments includes a central axis and first and second housing sections. The first housing section includes a first fitting including a mating surface orthogonal to the axis and a tapered recess formed in the mating surface and coaxial with the axis. The tapered recess has a decreasing internal dimension at points further from the mating surface and terminates at a faceted recess. The second housing section includes a second fitting having a flange and a frusto-conical projection terminating in a faceted tip. When the first and second housing are coupled, the flange and mating surface are aligned, the frusto-conical projection contacts an interior surface of the first fitting that defines the tapered recess, and the faceted tip seats within the faceted recess. The housing may include a head for housing sensor electronics and a shield that encloses the head and is spaced from the head by an air gap.
