FR100RD series Rogowski coil current sensor is a toroidal coil that is wound evenly over non-ferromagnetic material. It has no hysteresis effect, almost zero phase error, no magnetic saturation, and good linearity. The output signal is the differential of current vs. time. By integrating the output voltage signal, the input current can be truly restored, and its measurement current range can range from milliamperes to millions of amperes. Mainly used for AC leakage current, high current, high harmonic current, complex waveform current, transient inrush current, phase, electric power, power, power factor and other detection. With integrator, easy to integrate into other equipment, such as: electric energy meter field calibrator, multi-function energy meter, oscilloscope, digital multimeter, cable identification instrument, cable fault detector, double clamp grounding resistance tester, double clamp phase voltmeters, digital current recorders, etc., can measure and compare a variety of electrical parameters in an uninterrupted state.
FR100RD flexible coil current sensor coil part without any exposed metal conductor, non-contact measurement, safe and reliable; it’s small size, light weight, exquisite appearance, soft and flexible, suitable for narrow environments and cable intensive places; wide measurement range, high precision , reliability, wide response frequency bandwidth, users can customize coil length according to demand. Widely used in electricity, communications, meteorology, railways, oil fields, construction, measurement, research and teaching units, industrial and mining enterprises and other fields. Particularly suitable for industrial environments such as relay protection, thyristor rectification, frequency control, semiconductor switches, power electronics conversion equipment, arc welding and other serious signal distortion.
