Working Principle
The MT-1A operates by creating a high-intensity magnetic field around the workpiece. When a defect such as a crack or slag inclusion is present, magnetic flux leakage occurs. By applying magnetic powder (usually iron oxide), the particles accumulate near the defect, forming visible traces. Under proper lighting, these markings help inspectors determine the position, size, shape, and severity of the flaws.
Operating Conditions$
Operating Temperature: -10°C to +40°C
Storage Temperature: -20°C to +70°C
Relative Humidity: ≤ 80%
Environment: Should be free from strong vibrations, magnetic interference, corrosive substances, and excessive dust.
Operating Instructions & Precautions
Setup & Connection: Connect the detector to the power source and start the device. Adjust the polar distance according to the workpiece size.
Applying Magnetic Powder: For dry powder detection, evenly spread the powder on the workpiece.
Flaw Detection: Move the electromagnetic yoke at 40mm/s, ensuring proper contact with the workpiece.
Overlap Considerations: Ensure overlapping scans are less than 25mm to prevent missing defects.
Assessing Defects: If an indication appears, remove excess powder and verify the flaw. If unclear, clean and retest the surface.
Image Capture & Reporting: If a defect is confirmed, capture the image and generate a test report.
Maintenance & Care
Handle with Care: Avoid unplugging cables while the device is powered on.
Cleaning: Use a soft cloth to clean oil and debris after each use to prevent contamination.
Storage: Keep the device in a dry, well-ventilated area, free from extreme vibrations.
Button Sensitivity: Do not press buttons excessively or use metal objects to operate them.
Battery & Charging: Use only the original charger; charge time is approximately 4-6 hours. The red indicator signals charging, and the green indicator shows a full charge.
Electromagnetic Yoke Care: Ensure the yoke is well connected to the workpiece. When not in use, lubricate the joint to prevent rust.
