Wire Rope Computer Detector MRT10-S
Brand: Mitech
Model: MRT10-S

Product Overview

The MRT10-S Wire Rope Flaw Detector is a state-of-the-art non-destructive testing (NDT) device developed by MITECH CO., LTD. Utilizing the principle of magnetic leakage, it can accurately detect internal and external defects in wire ropes, including broken wires, corrosion, and wear. The system also calculates changes in the metallic cross-sectional area and generates diagnostic reports based on industry standards and regulations.

This device incorporates advanced MRT magnetic sensor technology and an independent data collection module, allowing direct data transfer to a computer via RS232 or USB. The software uses wavelet transformation algorithms for real-time data acquisition, control, analysis, visualization, and storage. With dynamic target tracking, the MRT10-S provides continuous monitoring, real-time defect alarms, and automatic evaluation. The compact and lightweight design makes it ideal for various industries requiring precise wire rope inspections.

Applications

The MRT10-S Wire Rope Flaw Detector is widely used in industries that require regular inspection and maintenance of wire ropes, such as:

• Hoisting Machinery – Cranes, lifts, and heavy-duty lifting equipment
• Coal Mining – Mine hoists and conveyor cables
• Oil & Gas – Oilfield drilling rigs and mining machines
• Elevator Systems – Inspection of traction and suspension ropes
• Cableways & Rope Bridges – Ensuring the safety of cable car systems and suspension bridges
• Port & Shipbuilding – Cargo hoisting ropes and marine rigging
• Railways & Construction – Wire rope usage in railway signaling and structural engineering
• Electric Power & Water Conservancy – Tensioning cables in hydroelectric and transmission towers

Working Principle

The MRT10-S operates by magnetizing the wire rope using a high-intensity permanent magnet steel excitation system. When the rope passes through the MRT sensor, defects such as broken wires and wear create magnetic flux leakage (MFL). These magnetic signals are captured, converted into voltage, and processed into digital values. The built-in mathematical model software decompresses and analyzes the data, displaying the exact location, severity, and type of defect in real time. This allows inspectors to assess wire rope integrity and predict service life based on quantitative analysis.

Operating Conditions

• Temperature: -20°C to +50°C
• Pressure: 86 – 106 KPa
• Relative Humidity: ≤85%
• Storage: Keep in a dry environment, free from strong magnetic interference.

Operating Instructions & Precautions

1. Software Installation: Insert the software CD (or connect a digital file) to install the MRT V3.0 system.
2. Device Connection: Connect the RS232 or USB cable from the detector to the computer.
3. Software Initialization: Open the MRT.exe program to access the main control interface.
4. Shortcut Setup: Right-click MRT.exe to create a desktop shortcut for quick access.
5. Start Testing: Use the sampling, broken wire analysis, and wear detection functions within the software.
6. Real-Time Monitoring: Observe live waveform changes, numerical defect values, and set alarm thresholds.
7. Automatic & Manual Evaluation: The system provides automated safety assessments, but manual analysis can be performed for accuracy.
8. Report Generation: Save, print, and export reports in Word or Excel format for further review.

Maintenance & Care

• Battery Management: Charge the AD battery before use and avoid continuous operation beyond 9 hours.
• Magnetization Precaution: Do not operate the detector near mechanical wristwatches to prevent magnetization effects.
• Avoid Magnetic Interference: Keep the sensor away from computers, floppy disks, and printers to prevent signal distortion.
• Proper Connection Sequence: Always plug in the data cable before turning on the power to ensure proper initialization.
