High isolation transducers for voltage, current and speed signals in the railway industry

The Knick Group has been a proven partner of the international railway industry for more than 50 years. With an exceptionally high MTBF of 2165 years (Mean Time Between Failures) in DC high-voltage transducers, which was determined based on real field data, Knick has set an industry benchmark.

This quality standard is also pursued for all other products for the railway industry by the 230+ employees in the Berlin, Germany, Headquarters and in their international subsidiaries.

On this basis, Knick supplies pioneering measuring technology that increases cost-effectiveness and safety in rail transport – on track and in DC traction power supply. With devices for precise measurement of current and voltage as well as for isolated signal conversion for the railway sector, Knick impressively demonstrates “The Art of Measuring”.
