RM O-RCA Optical Rail Corrugation Analyzer
(highly accurate laser-based system) Non-contact longitudinal rail profile and roughness measuring system for rails in
tracks and switches. Suitable for mounting on rail vehicles and hi-rail vehicles

Product description:
Rail surface irregularities of the order of microns (0.001mm) in amplitude are important in the generation of wheel/rail rolling noise and vibrations. The O-RCA is a compact and easy to install high precision contactless measuring device to obtain a continuous longitudinal measurement of irregularities such as corrugations on the rail head. The O-RCA can be fitted to trains, hi-rail vehicles and wagons and can be used on various track gauges (standard, narrow or wide gauge).
O-RCA
Applications:
- Monitoring of rail quality
- Detection of rail roughness and corrugation
- Detection and classification of both short and long waves
- Assessment of mobile rail treatment results e.g. rail grinding and milling to EN 13231 standards
Main characteristics:
- Measurements that are highly accurate and repeatable
- Relatively simple installation and setup
- Non-Contact measurement system using optical sensors
- Suitable for any track gauge
- User-friendly software for acquisition and review of measurement data
- Robust yet light weight design
- Extensive product support
- No minimum speed is required for accuarte performance of the system

TECHNOLOGY FROM THE LEADERS IN RAIL MEASUREMENT SYSTEMS

The O-RCA gives reliable measurement results of irregularities on the rail head over the full wavelength range as per EN13231-2:2020 and earlier versions of this standard. The user-friendly reporting software allows for superimposing measuring runs, setting required tolerance limits and showing the % exceedances.
