Abstract
A system can take transverse measurements of an elongated workpiece. The tem has a base for holding the workpiece oriented in an axial direction. A carriage mounted on the base can move axially. This carriage has a linear measurement device for providing a linear signal signifying the axial position of the carriage. An ultrasonic assembly is mounted on the carriage, and includes a nozzle for projecting a stream of liquid against the workpiece. This ultrasonic assembly also has an ultrasonic transducer for transmitting an ultrasonic wave into the stream and for detecting an ultrasonic wave returning in the stream. This ultrasonic transducer has a transducer terminal for exchanging signals signifying the occurrence of ultrasonic waves transmitted into and returning from the stream. A control device is coupled to the transducer terminal for (a) exchanging signals with the ultrasonic transducer, (b) initiating transmission of an ultrasonic wave into the stream, and (c) receiving a signal signifying the return of ultrasonic waves in the stream. This control device can provide a sense signal signifying the operation of the ultrasonic assembly. The system also has a signal processor coupl…
