摘要：
The encapsulated transducer (10) includes an injection molded encapsulation (20) having a front end (22) and a back end (24). The encapsulation (20) ensconces a sensing element (40) proximate the front end (22) and a portion of a cable (60) which extends from the back end (24). The sensing element or coil (40) is electrically and mechanically connected to the cable (60) by a pair of suitably sized front and rear ferrules (80), (90) secured to a center and coaxial conductor (66), (70) of the associated cable (60) thereby forming a coil and cable assembly (110). At least the rear ferrule (90) includes a shoulder (100) for firmly anchoring the coil and cable assembly (110) within the encapsulation (20). In addition an injection molding process provides the durable encapsulation (20) which bonds with a dielectric (68) of the cable (60) and symmetrically locks the coil and cable assembly (110) therein.
