High-Frequency Monitoring
High-frequency listening (Airborne & Structure-Borne Ultrasound) is a precise measurement method that detects high frequencies beyond the hearing range of the human ear. The method is particularly effective for detecting the earliest stages of faults in machinery and pressure systems – before they cause damage.
Sensors provide early indications of:
- legibility (bearing defects)
- Air leakage in pressurised systemsAir leaks)
- cavitation in pumpscavitation detection)
- Electrical discharge and emission in electrical equipment (electrical discharge / arcing)
- Faults in end and steam systems (valve leakage)
The solution is particularly useful in noisy industrial environments where conventional measurements are difficult. High-frequency listening supports predictive maintenance (predictive maintenance) and reduces unexpected downtime (reduction of downtime).
HD offers both portable ultrasound equipment for routine measurements and solutions that can be integrated with continuous monitoring systems.
