Abstract
A transducer assembly for maintaining a transducer in contact with, and in alignment with, a surface includes a pair of opposed swivel bars, each of which is pivotably mounted to a cradle. The swivel bars are free to pivot about a roll axis. Two tension arms are pivotably mounted to one of the swivel bars. Each tension arm resiliently urges an end of the transducer into contact with the surface. One of the swivel bars supports two spaced-apart wheels whose contact with the surface is effective to rotate its swivel bar into a predetermined rotation about the roll axis. The transducer, being attached to the swivel bar by one of the tension arms is also rotated into a predetermined angle about the roll axis.
