operation is simple the latest NDT product developed by MITECH MRT10-S wire rope computer detector wire rope tester

Overview

MRT10-S wire rope computer 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. 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.

Technical Parameters

• Detection range: Φ1.5-300mm (User should choose sensor according to the diameter of wire rope as different sensors have different ranges.)

• The best detection efficiency: 0.3 to 1.5m/s

• Allowed clearance: 0-15mm (allow clearance between guide sleeve and wire rope)

• The best clearance: 2-6mm

• Broken wires qualitative accuracy: 99.99%

• Broken wires quantity error: allow monofilament miscalculation

• No error quantitative detection for the number of focused broken wires on single point: ≥92% for more than 100 times

• Error sensitivity: ± 0.055%

• Accuracy indication error: ±0.2%

• Length indication error: ±0.2%

• Power: 5v battery of computer power

• Sensor weight: specifications <10kg

Working Principle

The principle of MRT10-S is that when the wire rope quickly passes 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 of 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.
