Which component in an ultrasonic immersion system is responsible for adjusting and maintaining a known transducer angle?

In an ultrasonic immersion system, the component responsible for adjusting and maintaining a known transducer angle is the manipulator. The manipulator enables precise control of the positioning and orientation of the transducer in relation to the test object, ensuring that the ultrasonic waves are emitted at the correct angle for effective inspections. This is crucial in obtaining accurate data during ultrasonic testing, as the angle of incidence can significantly influence the reflection and refraction of the sound waves, thus affecting the quality of the inspection.

While other components like the transducer holder and support arm provide essential support and stability for the transducer, they do not facilitate the adjustment or maintenance of the angle in the way that the manipulator does. The angle gauge, on the other hand, is typically used to measure or verify angles but does not actively adjust them during testing. The manipulator’s ability to adjust the transducer's angle dynamically makes it integral to the operation of an ultrasonic immersion system.
