Rogowski Coil MFC190
Rogowski Coil MFC190

Rogowski Coil MFC190 (12 mm cross-section) is a flexible current transducer based on the Rogowski principle. MFC190 coils are available in different sizes and can be supplied according to the customer's design, therefore they can be used in all applications where traditional transducers do not fit due to their size and/or weight. Flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in many cases where traditional current transducer is not the adequate solution.
The MFC190 coil is equipped with a shield against the influence of external magnetic fields, therefore it ensures stable measurement from low currents up to hundreds of kA. Rogowski coils must be connected to an electronic integrator for 90° phase shift compensation and frequency equalization.
