About us

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 250+ employees in the Berlin, Germany, Headquarters and in their international subsidiaries.

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”.

High Voltage Transducer P45000

Space-saving high-voltage transducer up to 4500 V DC and 3000 V AC with SIL 2 for DC voltage measurement on-board trains for all DC and AC powered rolling stock. It is especially designed for space-saving and flexible (lying or upright; screw fastening or DIN rail mounting) installation in traction inverters and auxiliary power converters. With very flexible mounting options: upright, horizontal screwed or snapped onto 35 mm DIN rails or in a stack.

The P45000 has mechanical and electrical interfaces that are customary in the rail industry.

Speed Signal Doubler P16800 SIL2/SIL4

The P16800 doubles the signals of a speed sensor. In addition, it converts them as required regarding signal type (current/voltage) or frequency. In this way, any speed sensor can be connected to different controllers. The device simplifies the retrofitting of rail vehicles with control systems that require speed information and helps to quickly and cost-effectively implement the extensive requirements for odometry that e.g. result from the European standardized train control system ETCS.

P16800 signal multiplier multiplies encoder signals and adapts them to the system control.

P52000VPD - Voltage Presence Detection

The P52000VPD detects voltages between 50 and 4200 V. The input signal is compared to a threshold value and the resulting binary information is galvanically isolated and transmitted to the output circuit. When the input voltage exceeds the set threshold value, a solid state relay opens, signaling the presence of voltage at the input.
Used in traction power supply on rolling stock, for the operation of motorized disconnects (MODs)and for the verification of live rail or catenary.
