Railway sensor

Bestech is now distributing a new product by Micro-Epsilon designed for checking wear and tear of railway tracks, which it claims is quicker and more accurate than “conventional methods”.

The new Micro-Epsilon scanCONTROL 2800 uses laser profile sensors to measure for deformations and other irregularities of railway tracks. Since trains are becoming faster and more widely-used — especially with an increasing amount of people becoming ‘environmentally-aware’ and favouring public transport to motor-vehicles — Bestech says this new test and measurement product is imperative for the rail industry.

“Scanning laser sensors have been available on the market for a long time, however tests have shown that they are too slow and cannot deal with the surface of railroads which can be lustrous metallic in some places but dull and corroded in others,” says Bestech.

“However, the scanCONTROL 2800 profile sensor has no such problems and is highly versatile in that regard.”

The scanCONTROL’s measurement procedure for profiling railway tracks requires two synchronised, non-contact sensors per rail, equating to four sensors on an inspection car.

Accurate measurements can be taken at speeds of up to 100km/h, and the focusing distance can be modified in the sensors to obtain optimal results, allowing for a complete, accurate and fast three-dimensional profile of the track, meaning safety can be ensured in an efficient and cost-effective manner, says Bestech.

The measured results can be continually-compared to an ideal profile programmed onto the measurement computer. Any excess of tolerances is marked on the computer, to allow for maintenance work to be carried out in a timely manner.
