Dynamic ultrasonic gauge apparatus with a ferrule mounting to position a transducer

摘要

An ultrasonic gauging apparatus is disclosed suitable for dynamic ultrasonic gauging in the harsh environment of a tube forming operation. An ultrasonic transducer is positioned in a tubular member by a ferrule mount. The tubular member is attached to a platform having spring biasing that permits limited motion of the transducer while maintaining a preselect orientation of the transducer relative to the tube.
