Transductores de alto aislamiento para señales de voltaje, corriente y velocidad en la industria ferroviaria

Precision Devices for the Rail 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”.

Medición de alta tensión y corriente en material rodante

Knick offers highly isolating transducers for measuring voltage and current. P45000 is the high-voltage transducer with the smallest footprint and SIL 2. It is used for direct current measurement on board all trains driven with direct and alternating current.

Medición de alta tensión y corriente en material rodante

P16800 makes it easy to retrofit rolling stock with control systems through the safe (SIL2/SIL4) conversion of speed sensor signals for odometry systems.

Medición de tensión e intensidad en subestaciones de corriente continua

Substations for direct power supply up to the upper one-digit MW range and the grid segments they supply must be effectively secured against short-circuits. The protective mechanism must reliably interrupt high currents as quickly as possible and limit the power flowing into the short circuit.
