ABSTRACT:
A housing comprises a first top cylindrical section having an internal hollow which is manifested by three concentric sections, each of a larger diameter to give the sidewall of the housing a step-like cross section. A transducer assembly is positioned within the hollow of the top section and bonded to the inner wall. An annular ring is positioned in the hollow within the second section and accommodates small diameter wires directed from said transducer assembly through the aperture and bonded to metallized land areas on the undersurface of the annular member. The metallized areas also contain a separate conductive post which is directed from the land areas. A second bottom housing accommodates tubular conductive members which are aligned with the post member. When the second housing is emplaced within the first housing the posts are positioned within the tubular conductor members where they are welded to the tubular members to form a permanent assembly. The housing provided is extremely rugged and is adapted for operation in deleterious environments.
