Rail Corrugation

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.

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.
