Working Principle

? Based on optical or laser measurement technology, it emits light or laser beams onto the rail surface, then receives the reflected light, and analyzes the time or intensity changes of the reflected light to construct the rail's profile shape. Some also use mechanical contact measurement, where a probe contacts the rail surface and records its displacement to depict the profile.

? High-precision measurement: It can accurately measure various parameters of the rail profile, such as rail head height, rail base width, and rail web thickness, with precision down to the millimeter or even micrometer level, providing accurate basis for rail maintenance and replacement.

? Fast and efficient: It can complete the profile measurement of a section of rail in a short time, greatly improving inspection efficiency and minimizing impact on railway operations.

? Non-contact measurement: Most profile measuring instruments using optical or laser technology do not require direct contact with the rail surface, avoiding damage to the rail and reducing instrument wear, thereby extending service life.

? Easy operation: With a user-friendly human-machine interface, operators can become proficient after simple training, reducing reliance on specialized technical personnel.

? Strong data processing capabilities: It can process and analyze measurement data in real-time, generate detailed measurement reports, and connect to computers or other devices for data transmission and sharing, facilitating subsequent data analysis and management.
