The bearing 324, the transducer 32, the positioning member 31, and the positioning end cap 312 can be caused to move axially on the rotational shaft 325. For example, the bearing 324, the transducer 32, the positioning member 31, and the positioning end cap 312 are hinged or otherwise coupled, respectively, such that rotation of the shaft 325 rotates the bearing 324, the transducer 32, the positioning member 31, and the positioning end cap 312.
