Level crossing warning system

The Level Crossing Warning System (LCWS) is an end-to-end SIL 2 certified product that detects approaching trains using SIL 4 certified acoustic sensors. The acoustic sensors are mounted on the rails and listen for the distinct sound waves generated by approaching trains. The digital data is analysed by a nearby Control Unit, which activates the customer’s preferred warning devices at the appropriate time.

All components of the LCWS are installed at the the level crossing site, thereby reducing cabling compared to competing systems. This makes the LCWS quick to install and easy to maintain, all at a minimal life-cycle cost.
