System Characteristics 1. The design standard of this system is BS EN 15610:2009. 2. The end face and the displacement meter of the equipment adopt millimeter scale to facilitate accurate positioning of test coordinates. 3. The industrial lemo interface is adopted to ensure the reliability of equipment testing and data transmission. 4. There are two kind of test instruments (single point & three point) to meet different test needs of the user. 5. Not only can it be used for rail roughness testing (related to the noise of the wheel-rail), but also can be used for the corrugation test.
