Improved safety requirements in railroad rolling stock often require additional, independent speed signals for on-board train control. However, frequently installation space for additional sensors is lacking. The solution are multi-system speed sensors from Lenord+Bauer. These combine different signal patterns in a compact flange housing.
Thanks to galvanic isolation, the sensors provide the necessary speed signals for up to four control systems without feedback between them and are suitable for operation at different supply voltage levels. The specific signal characteristics can be combined for anti-skid protection as well as for traction and train control.
