How It Works
The ultrasonic flaw detector operates on the principle of ultrasonic pulse reflection. When a flaw or defect is present in a material, the interface between different mediums causes a change in acoustic resistance. The ultrasonic pulse encounters the defect and is reflected back. The probe detects these reflected waves, and the device displays the defect’s position, depth, and shape in real-time.
Applications
The Mitech MFD350B is widely used in industries that require high-precision quality control and structural integrity testing, including:
- Manufacturing & Metal Processing – Detects internal defects in fabricated metal components.
- Aerospace & Automotive – Ensures structural integrity of critical parts such as axles and shafts.
- Oil & Gas – Inspects pipelines, pressure vessels, and storage tanks.
- Construction & Infrastructure – Evaluates weld quality in buildings and bridges.
- Power & Energy – Used in turbine blade inspection and maintenance.
Operating Method
- Connect the probe to the instrument using the probe cable.
- Turn on the device and select the appropriate detection channel.
- Calibrate the probe:
- Straight Probe: P-Delay
- Angle Probe: P-Delay, X-Value, Angle
- Set AVG/DAC curve based on the selected probe type.
- Adjust detection settings as needed.
- Perform flaw detection on the workpiece.
- Record and analyze the flaw signals.
- Power off the device after use.
Safety & Maintenance Guidelines
Proper Handling
- Avoid pressing buttons too hard to extend keypad life.
- Keep the instrument clean and dry after use.
- Store in a dust-free, non-corrosive environment.
Battery Maintenance
- Charge before first use and after long storage periods (3+ months).
- Avoid frequent partial discharges to prolong battery life.
Instrument Cleaning
- Use a moist cloth with mild detergent or alcohol for cleaning.
- Do not use solvents or methyl alcohol, as they can damage plastic components.
Cable Management
- Do not twist or pull probe cables forcefully.
- Always hold the connector base when plugging or unplugging cables.
Warranty & Support
- 2-year warranty with lifetime maintenance service.
- Contact Mitech or an authorized agent for repairs.
- Do not attempt self-repairs without manufacturer approval.
