The system is highly adaptable according to specific customer requirements. „M“ sensor series is specifically designed to be able to detect different unconventional types of trains. By processing raw analogue signals from wheel sensors, the system retrieves overview of specific application environment. BO23-MTA system shows exceptional results in railwheel distinguishing from other metal objects and adaptation to environmental influences like temperature change, EMI, overvoltage, traction currents, different rail and wheel/train profiles, worn-out flanges and rails. Furthermore, implemented self adjustment to aging of system components and preventive maintenance features increase the availability of the system.
