摘要： A threaded connection make up monitoring system includes an acoustic emission transducer operatively connected to one positioned to capture an acoustic signature associated with forming the threaded connection between a first member and a second member. A controller is operatively coupled to the acoustic emission transducer. The controller is operable to receive a signal from the acoustic emission transducer embodying the acoustic signature. The controller is operable to output a signal indicating whether the acoustic signature represents a properly made up threaded connection of the first member and the second member or whether the acoustic signature represents an improperly made up threaded connection of the first member and the second member.

摘要： Provided is a device for measuring at least one parameter of an extruded flat conductor cable in a water bath that follows the extruder. The device distinguishes itself in that the flat conductor cable is guided with one of its flat sides essentially perpendicular across an ultrasonic head arranged in a water bath and that the ultrasonic head is a displaceable ultrasonic head that can be displaced crosswise to the longitudinal direction, or the ultrasonic head is a stationary ultrasonic element row that extends crosswise to the longitudinal direction of the flat conductor cable. This device allows measuring the total width of the flat conductor cable, such that different parameters can be determined.
