MFC150/F Rogowski coil with a built-in Integrator
The MFC150/F is offered as an all-in-one solution with a built-in integrator. This eliminates the need for any external conditioning equipment, simplifying installation and delivering significant space and cost savings.
Description
Rogowski Coil MFC150/F (8 mm cross section) is a flexible current sensor based on the Rogowski principle. The MFC150/F is a current measurement solution with a built-in integrator, eliminating the need for any external integrator-conditioner equipment, simplifying installation saving space and cost. This sensor system provides the required phase and frequency compensation required for energy measurement applications. MFC150/F coils are available in different sizes and sensitivities sand can be supplied according to customer’s requirements. The MFC150/F current sense coil is provided with a shield minimising effects from external magnetic fields, enabling a stable measurement from small currents to many kA.
