Predictive Maintenance Through Ultrasound
SDT Ultrasound
Hear problems before they become failures
About SDT
SDT is a global leader in ultrasound-based condition monitoring solutions, helping industrial teams understand the real health of their assets. For over 45 years, SDT has focused on using airborne and structure-borne ultrasound to predict failures, reduce energy losses, and improve equipment reliability.
Ultrasound is one of the earliest indicators of mechanical, electrical, and process-related faults. SDT’s solutions enable maintenance teams to detect problems long before they are visible through vibration, thermal imaging, or electrical failure, making ultrasound a critical pillar of modern predictive maintenance programs.
