Reliable encoders for railway vehicles

Baumer Electric: With its BMIV line, Baumer presents an encoder designed for the harsh operation on railway vehicles. Multiple channel outputs allow simultaneous wheelset speed information to multiple systems, also 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 of encoders for railway vehicles are enormous. They 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. High shock and vibration loads resulting from the direct encoder installation on unsprung 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 totally resistant to all loads encountered during railway operations. Aside from compliance with all railway standards, the BMIV also offers SIL 2 certification. Baumer has decades of experience in sensors intended for use with railway vehicles. Thanks to close cooperation with our customers coupled with continuous innovations, we are able to offer tailor-made solutions using the latest technology and offering the highest level of customer benefit.
