Encoders for railway vehicles

October 2009 Sensors & Transducers

Baumer has designed an encoder for harsh operation on railway vehicles that features multiple channel outputs to allow simultaneous wheel-set speed information for multiple systems with differing pulse rates. These include systems for slide control, speed and slip regulation as well as those to suppress torsion vibration.

The demands made on encoders for railway vehicles are enormous. The encoders must remain completely unaffected by extreme environmental influences such as dirt, oils, grease, spray water, condensation, large temperature differences, as well as high and low temperatures. The high shock and vibration loads resulting from direct encoder installation on un-sprung pivoted bogies are a particular challenge.

All Baumer encoders for railway vehicles operate on the proven MAGRES principle. This magnetic sensing method offers extreme reliability and is resistant to all loads encountered during railway operations. Aside from compliance with railway standards, the BMIV also offers SIL 2 certification. Baumer has decades of experience in sensors intended for use with railway vehicles, and, thanks to close cooperation with customers, is able to offer tailor-made solutions using the latest technology and offering high levels of benefit.
