Product Overview
MRT10-S wire rope flaw detector is the latest NDT product developed by Mitech CO.,LTD. Based on the principle of magnetic leakage, it can real-time detect the internal and external wire rope defects such as broken wire, corrosion, wear and calculate the changes of quantitative values on metallic cross-sectional area then generate diagnosis report in accordance with the current standards and procedures. The hardware part adopts international advanced MRT magnetic sensor and independent data collecting module, can directly save data in computer through RS232 or USB main line, The principle of software part is the wavelet transformation, achieves the functions such as data acquisition, control, analysis, display, storage and so on. By unique dynamic target tracking, it can observe data signal and change situation continuously and dynamically, real time display results, alarm and automatic evaluation. The equipment is easy to carry and operate, with high precision, good repeatability, can locate damage accurately. It is widely used in all kinds of industries of hoisting machinery, coal mine hoist, the oil field mining machine, elevator, cableway, port machinery, cable bridge, mine, oil wells, wharf, shipbuilding, war industry, water conservancy, electric power, railway, construction and other industries related with testing broken wires on wire rope and the wear.
Function & application
It is widely used in all kinds of industries of hoisting machinery, coal mine hoist, the oil field mining machine, elevator, cableway, port machinery, cable bridge, mine, oil wells, wharf, shipbuilding, war industry, water conservancy, electric power, railway, construction and other industries related with testing broken wires on wire rope and the wear.
Working Principle
The principle of MRT10-S is that when the wire rope quickly pass the sensor, the permanent magnet steel axial of the sensor magnetizes steel wire rope deeply until saturate. Defects such as broken wires and wear synchronously produce magnetic leakage field and magnetic flux change, magnetic signals spreading space is concentrated by poly copper and converted into voltage, changes into digital values by wide angle hole array element group, then compress and send digital signal to computer. Decompress the data real time by the three dimensional mathematical model software. Then displays specific quantitative number to show the inside and outside broken wire, corrosion, wear, metallic cross-sectional area changes of the wire rope, in accordance with the current standard to generate assessment of safety and service life of wire rope.

Operating Method and Attentions
1) Insert this system software compact disc, (or connects other medium having the software file to the computer), open the compact disc file, the screen will appear some folders such as "MRT V3.0".
2) Copy the "MRT V3.0" folder into one disk root,
3) After the copy, open "MRT V3.0" folder, press "MRT. exe" to operate the program.
4) In order to operate simply, the user can right-click the "MRT.exe", and send it to the desktop as a shortcut. When next time using this software, click the icon to open.
The operation(Alt+E) item contains the sampling, broken wire analysis, and deterioration analysis three functions items. It is the main part of this system with the sampling control and processing analysis functions for primary signal of tested wire rope.
Instrument Maintenance
Before using, charge the AD battery, and the battery could not continuous work surpass 9 hours.
Be sure not to operate with mechanical wristwatch, avoid magnetization.
Be sure not to put the sensor near the computer, the floppy disk, the printer, to avoid the strong magnetic field affection.
Be sure to connect the plug first, then the power.
