ASC RAIL Sensors to Improve Railway Performance
This article first appeared in the Railway-News magazine, Issue 3 2024.
ASC’s RAIL sensor series provides highprecision, robust yet flexible inertial sensor technologies. The tailored solutions support railway customers in improving the safety, capacity and overall productivity of their rolling stock.
Expanded ASC RAIL Series Meets Applicable EN 50155 Standards
“Through the rigorous testing and documentation of our RAIL sensor series’ performance, we’re making it significantly easier for railway operators to configure and implement individual inertial sensor solutions on their rolling stock. They can now rely on a proven set of stable precision sensors ready for installation, which meet the required norms and significantly reduce individual documentation requirements on the part of the operator.”
Pre-qualified accelerometers of type ASC RAIL-x152LN are already being used by European and global rail operators. In June 2024, the sensor series was expanded with an additional accelerometer type ASC RAIL-x151LN, featuring a more compact housing to be able to fit into smaller spaces. The same smaller housing was used for the new gyroscopes of type ASC RAIL-27×1. For all three models, comprehensive evaluations by an independent testing lab resulted in clear outcomes for ASC’s reliable, accurate RAIL series.
The following tests have been performed according to railway standard EN 50155:2021 to confirm climatic resistance and dynamic-mechanical robustness:
- Low temperature storage test – test A
- Low temperature start-up test – test A (OT6)
- Dry heat test – test B (OT6) • Damp heat, cyclic – test Db
- Insulation tests (before and after damp heat, cyclic)
- Vibration, broad-band random – long time test Fh (category 3: axle-mounted)
- Vibration, broad-band random – functional test Fh (category 3: axle-mounted)
- Shock testing – test Ea (category 3: axle-mounted)
