The ultrasound receiver – available in four convenient kits – detects and converts ultrasonic (>20 kHz) noise produced by mechanical, pneumatic, hydraulic, and electrical systems down to an audible range you can hear. Changes in the amplitude and characteristics of the ultrasound are comfortably detected in noisy plant environments. Leaks are easily pinpointed. Electrical issues are safely exposed. Equipment problems such as bearing over- and under-lubrication are diagnosed early, enabling ultrasound to complement vibration monitoring and enhance condition-based maintenance programs.
