ETCR002F Rogowski Flexible Coil Current sensor with integrator(Integral Type) is composed of flexible coil and host, the integral structure is more convenient to use and operate. The coil without any bare metal conductor, no-contact measurement, safe and reliable. It is small in size, light in weight, exquisite in appearance, soft and flexible, suitable for narrow environment and flat cable dense place. The measurement range is wide, high accuracy, strong reliability and wide response frequency band (0.1 Hz-1 MHz). Users can customize the coil length according to the request. Widely used in electric power, communications, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. Especially suitable for the flat cable dense place, current test of transformer grounding core , thick wire and cable, relay protection, silicon controlled rectifier, frequency conversion speed regulation, semiconductor switch, power electronic conversion equipment, arc welding and other industrial environment with serious signal distortion.

ETCR002F Rogowski Flexible Coil Current sensor with integrator (Integral Type), which is Rogowski coil current sensor, adopts advanced Rogowski Coil technology, which is a loop coil uniformly wound on non-ferromagnetic materials, with no hysteresis effect, almost zero phase error, no magnetic saturation, high linearity and strong anti-interference ability. The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The measured current ranges from milliamperes up to ten thousands of amperes. It is mainly used for the detection of AC leakage current, large current, higher harmonic current (up to 400 times), complex waveform current, transient impulse current, phase, electric energy, power and power factor. With integrator, it is easy to integrate into other equipment, such as phase detection analyzer, industrial control device, data recorder, oscilloscope, harmonic analyzer, power quality analyzer, high-precision digital multimeter, transient impact recorder, distributed measurement system, protection system, etc.
