Our Rail solutions
To improve safety, efficiency and reliability when moving passengers and freight over long distances, the rail transport sector looks to advances in technology. Sensors, switches and motion control systems are critical elements, working together to optimise train performance, enhance passenger safety and contribute to the overall reliability and sustainability of rail transportation systems.
Types of Sensors supplied for Rail
We supply the essential components for passenger and freight train rolling stock as well as rail infrastructure including tracks and maintenance depots.
These contribute to safe, efficient and reliable operation by monitoring various parameters and controlling systems. Temperature sensors measure temperatures in brakes, bearings and motors, door position sensors monitor the status of train doors to prevent them opening during transit, while vibration sensors monitor the health of components and detect anomalies.
Example applications
EPT pressure sensors monitor
the compressor system pressure
in rail HVAC units.
Pneumatic pressure for opening
rail passenger doors is
controlled using EPT
pressure sensors.
A linear sensor detects
displacement or voids along the
rail track to ensure safety.
On service lorries, linear sensors
help position railtrack wheels
accurately for operation.
Rotary Hall sensors provide position
feedback on the tram’s master
controller to regulate speed.
A linear position sensor mounted
on the bogey wheel measures
rail track condition
during operation.
