Half a century of excellence
2025 marks a milestone for SDT—50 years of pushing the boundaries of ultrasound technology in predictive maintenance. From our humble beginnings in 1975 to becoming a globally recognized leader, our journey has been driven by a deep commitment to innovation, quality, and customer satisfaction.
The vision that started it all
SDT’s story begins with Joseph-Henri Degraeve, who saw an opportunity in the midst of an oil crisis. His fascination with ultrasound technology, combined with hands-on experience in the field, led to the development of solutions that changed the reliability landscape. His pioneering spirit set the foundation for a company that would become a key player in industrial maintenance.
With each decade, SDT continued to evolve, led first by André Degraeve and now by Benoit and Pauline Degraeve. While technology advanced, our core mission remained the same: to listen, to innovate, and to provide solutions that meet the real needs of industries worldwide.
Innovation that stands the test of time
Over the last five decades, SDT has introduced groundbreaking ultrasound solutions that empower industries to improve energy efficiency, reliability, and sustainability. Our technology has helped businesses detect leaks, monitor equipment health, and optimize lubrication, saving costs and reducing environmental impact.
A heartfelt thank you

As we celebrate 50 years, we are more committed than ever to shaping the future of ultrasound solutions. Here’s to the next 50 years of innovation, excellence, and collaboration!
