◆ the test results can meet the standards of different industries and can be displayed in the form of the number of broken wires and the ratio of the broken wire area to the total broken wire area.
◆ computer USB interface for direct sampling, processing and analysis, with online sound and light alarm and real-time display results.
◆ sensor circular structure, circumferential surround, axial magnetization, magnetization of the wire rope to saturation state.
◆ The sensor adopts alloy aluminum shell, which is waterproof, dustproof, shockproof and moisture-proof.
◆ stable work, reliable performance, high detection accuracy, strong anti-interference performance, accurate data.
◆ software to adapt to Windows98/2000 / xp/Vista/windows7 various computer operating systems
◆ in accordance with the provisions of the national metrology law and the national production safety law, each instrument shall be inspected by the national metrology institute as a third party in accordance with the American standard ASTM1571, and the test report shall be issued to obtain the legal qualification.
◆ widely used in mining, ropeway, lifting equipment, elevator, port machinery, cable bridge and other fields.
Technical core and legal qualification
(1). Virtual instrument: infinite uncertainty of wire rope.Only by using virtual instrument technology, replacing traditional instrument with software, and using computer to directly sample, we can ensure no missed inspection and wrong judgment, just like watching a movie, scanning the whole process of wire rope, the results are accurate and repeatable.
(2). Three-determination instrument: according to the national standards for scrap of wire rope in different industries, this product applies electromagnetic qualitative, quantitative, positioning, online nondestructive testing of wire rope internal and external broken wire, rust, wear, metal sectional area change, loose strands, jumping wire, deformation, material abnormalities and other defects.
(3). Legal instruments: according to the provisions of the national metrology law and the national production safety law, each instrument is inspected by the national metrology institute according to the American standard of astm1571-2006 and GB/ t21387-2008 as a third party, and the test report is issued to obtain the legal qualification.
Technical indicators
Full range of wire rope diameter range can be detected: Φ 1.5-300 - mm (need to configure different series specifications sensor)
Relative speed between sensor and wire rope: 0.0 -- 6.0 m/s best: 0.3 -- 1.5 m/s
