Features The flexible coil current sensor is composed of a coil and a handle. The coil part has no exposed metal conductors. It is non contact measurement, safe and reliable. It is small in size, light in weight, exquisite in appearance, soft and flexible, and is suitable for narrow environments and places with dense cables. Using advanced Rogowski coil technology, it is a toroidal coil that is evenly wound on a non ferromagnetic material, with no hysteresis effect, almost zero phase error, no magnetic saturation, and extremely high linearity. The output signal is the differentiation of current to time. By integrating the output voltage signal, the input current can be truly restored, and the measurement current range can be from milliampere level to tens of thousands of amperes. Durable, wide measurement range, high accuracy, strong reliability, bandwidth response frequency (0.1Hz‑1MHz), made of high quality ABS material, long service life, long term use.
