Magnetic Flux Leakage (MFL) Probes
The Sonic - Revolutionize Your Inspections with High-Performance MFL Probes.
Our probes utilize high-energy permanent magnets or electromagnets to induce a strong and uniform magnetic field in the inspected material. This ensures optimal magnetization of ferromagnetic surfaces for precise flux leakage detection.
Equipped with advanced Hall-effect or giant magnetoresistance (GMR) sensors, the probe captures subtle magnetic field variations caused by defects, providing high-resolution detection.
Encased in corrosion-resistant materials such as stainless steel or composite polymers, the probe is designed for harsh environments, including underwater and high-temperature applications.
Integrated electronics amplify and process signals in real time, reducing noise and enhancing defect resolution.
The probe generates a strong magnetic field to saturate the ferromagnetic material being inspected. Any discontinuities, such as cracks or corrosion, disrupt the magnetic field.
When the magnetic field encounters a defect, a portion of the flux leaks out of the material's surface. Sensors detect this leakage and convert it into an electrical signal.
Advanced algorithms process the sensor data to differentiate between defect types, sizes, and locations, providing actionable insights to operators.
