product overview

The JW-GSS300 steel wire rope flaw detector can detect defects such as wire breakage, wear, rust, deformation, loose strands, wire jumping, and material changes inside and outside the steel wire rope online.

The test result report is displayed in the form of the number of broken wires and the ratio of the broken wire cross-sectional area to the total cross-sectional area of the steel wire.

Using computer USB interface for direct sampling, processing and analysis, with online sound and light alarm and real-time display of results function.

The sensor has a circular structure, circumferential surround, and axial magnetization, magnetizing the steel wire rope to saturation.

The sensing pocket adopts an alloy aluminum shell, which has waterproof, dustproof, shockproof, and moisture-proof functions.

◆ Stable work, high detection accuracy, and accurate data.

The software is compatible with Windows 98/2000/XP/Vista computer operating systems

Each instrument is inspected by a national metrology institution as a third-party according to the American standard ASTM1571 and Shanghai Q/NYNAY01 enterprise standard, and a testing report is issued to obtain legal qualifications.

◆ Applied in mining, cableway, lifting equipment, elevators, port machinery, cable bridges and other fields.

Technical and legal qualifications

1. Virtual instruments: By applying virtual instrument technology and replacing traditional instruments with software, computers can directly sample and process data without missing or misjudging. It is like watching a movie, scanning steel wire ropes with accurate results and good repeatability.

2. Three fixed instruments: According to the national standards for scrapping steel wire ropes in different industries, this product applies electromagnetic qualitative, quantitative, positioning, and online non-destructive testing to detect defects such as internal and external wire breakage, corrosion, wear, changes in metal cross-sectional area, loose strands, jumping wires, deformation, and material abnormalities in steel wire ropes.

3. Legitimate instruments: According to the provisions of the National Metrology Law and the National Safety Production Law, each instrument is inspected by a national metrology institution as a third party in accordance with the American standard ASTM1571 and the Shanghai Q/NYNAY01 enterprise standard, and a testing report is issued to obtain legal qualifications.
