The FR100R Series Rogowski Coil Current Sensor delivers accurate AC current measurement from milliamps to 10,000A. Designed for flexibility and precision, it uses non-ferromagnetic material and generates output as a differential signal, requiring integration to reconstruct the actual current waveform. With high immunity to electric field interference, wide frequency response, and minimal position error, FR100R is suited for power systems, research, railways, oil fields, and industrial environments where signal distortion is prevalent.
