Highly accurate laser-based measurement system evaluating corrugation over four critical wavelength bands. Compact High Performance Laser Technology and High Precision camera sensors are able to accurately predict any longitudinal surface defect at any working speed.
MERMEC Rail Corrugation Systems (RCS) detect and measure rail corrugations ranging from short (10-30 mm) to long (1000-3000 mm) wavelengths. The system uses optical measurements of the rail surface profile by recording surface displacements with cameras and lasers through the Versine transfer function.
The measurement, with a sampling step up to 5mm and speed ranging from 0 to 160 km/h, can be done with the train travelling in both directions, in all weather environment and in any light condition. Each system offers real-time data analysis and post processing analysis including acquisition, storage and diagram visualization for all the wavelengths. The post-processing allows advanced calculations like the standard deviation for each wavelength. System can be configured to work in Grinding configuration in order to validate grinding works with few micrometer accuracy.

The system uses inertial-measurements of rail surface profile and inductively measured surface displacements to detect and quantify the condition of the rail surface.
The measurement can be done with the train travelling up to 320 km/h in both directions and in all weather conditions. Each system offers real-time data analysis and post processing analysis. Real-time functions include data acquisition, storage and diagram visualization in all the corrugation wavelengths. Post processing allows for recorded data visualization and standard deviation calculations for each wavelength.

TecnoLine is a small, easy to manage rail corrugation measuring system. Its measuring principle is based on the measurement of displacements on the rail head through eddy current transducers, which are very high accuracy sensors. A PDA interface system makes storing, transferring and analyzing data a simple exercise.
