Introducing Knick Interface, your partner for precise electrical measurements in high voltage environments. With specialization in applications up to 4800 V, Knick delivers a variety of solutions to bring high-quality measurements into your projects.

Knick Interface showcases solutions for hydrogen fuel cell and electrolyzer stack and string monitoring. With high-isolation technology that protects against the full system potential, Knick delivers critical performance data to keep you informed.

Knick Interface highlights a staple in the product catalogue for voltage and current measurements by way of the P40000 series transducers. These devices uphold Knick's quality, defined as: Accuracy, Safety, Speed, and Ease of Use.

All aboard! From rolling stock to DC traction power supplies, Knick Interface provides high-precision electrical measurement solutions designed to meet the demanding requirements of the railway industry.

Discover how the P16800 speed signal duplicator from Knick Interface simplifies integration of modern train control systems like CBTC, Passenger Information Systems (PIS), brake control, and more, without the need to install additional speed sensors. This SIL-rated device duplicates existing speed sensor signals, supports Direction of Travel (DoT), and offers frequency division for flexible signal output. Designed to behave just like a real speed sensor, the P16800 helps avoid the high cost, complexity, and space limitations of adding new sensors to the train bogie, meaning there is no need for installing extra speed sensors in these space-constrained areas. Whether you''re upgrading your fleet or designing next-gen rolling stock, the P16800 delivers precise signal duplication with minimal effort.

Measure with Confidence. Isolate with Certainty. When you''re dealing with high-voltage DC systems, safety and precision can''t be optional. The P45000 from Knick delivers: • SIL 2 certified (SIL 3 redundant) • Continuous isolation up to 4.8 kV • Measurement up to 3 kV DC • Designed for demanding industrial and control environments Whether it''s measuring rectifier outputs, battery strings, or critical control systems, the P45000 ensures safe and accurate voltage monitoring in a compact and robust package.

Isolation is the foundation of safety and accuracy in high-voltage measurement. In this video, we highlight why Knick''s transducers are trusted across demanding applications from energy storage to rail and industrial systems. With true 3-port galvanic isolation, our devices ensure reliable signal integrity, protect equipment and personnel, and maintain precise measurement performance even in the harshest environments.
