Ninety percent of all machinery failures are preceded by changes in sound and vibration. The Comparisonics® sound-matching technology can detect these changes and alert maintenance personnel, who can take corrective action to avert a mechanical breakdown. The following kinds of problems can be diagnosed: imbalance, misalignment, damaged and worn bearings and gears, fatigue, cracking, internal breakage, and excessive wear and friction.

An unlimited variety of machinery can be monitored, including pumps, fans, motors, compressors, turbines, and engines, and complex machines that combine these components. The Comparisonics technology can contribute to the safety and performance of moving vehicles (automobiles, trains, airplanes) by monitoring their sounds and vibrations.
