ABSTRACT:
An encapsulatable sensor assembly includes an external housing with internal support components for retaining an active sensor element and associated electrical circuitry in a predetermined relationship while providing a plurality of internal sequentially interconnected cavities for facilitating a flow of an encapsulating material from an encapsulating material injection port to a vented overflow to assure a complete fill of the internal cavities to restrain the internal components. The sensor assembly provides a structure for a void free encapsulation and internal leadwire stress relief concurrently with location control of the internal components while also providing a combination which is easily adaptable to automatic assembly and encapsulation techniques.
