Ultrasonic technology

A multipatented technology called DND (dynamic noise discrimination) is now available in the AccuTrak VPX and BPX-WR ultrasonic detectors from Superior Signal Company Inc. DND is an ultrasonic technology which analyzes a broad spectrum of ultrasound and selects the proper frequency band of the fault automatically. DND allows for fast and accurate testing of compressed air leaks, vacuum leaks, steam traps, valves, bearings and electrical faults.
