FRC Series Flexible Rogowski Coil
FRC is a flexible current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. FRC rogowski coils are available in different sizes and can be supplied according to customer's design, therefore they can be used in all those applications, in which traditional transducers are not fitting due to its size and/or weight. Due to its specific features, FRC flexible rogowski coils is an extremely confortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.

Flexible Rogowski Coil With G1 Integrator
G1 is a USB-sized integrator, could be combined with any model and any size of FRC series rogowski coils to amplify the output signal. It's essential to equalize and shift by 90° the output signal from the rogowski coils. It consists of an active electronic circuit with negligible offset and a good linearity. Flexible rogowski coils with G1 integrator meets customer requirements for different outputs and allows for more interfacing with more measurement devices.
