Rogowski Coil MFC140

The Rogowski Coil MFC140 (7 mm cross-section) is a flexible current transducer based on the Rogowski principle. MFC140 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.
The MFC140 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.
The MFC140 is also available with a built-in integrator, without the need for external devices for 90° phase shift compensation and frequency equalization. This is an advantage because there are no external boxes, providing ease of use.
