ETCR100F Flexible Coil Current Sensor suitable for a large range of AC current, high harmonic current, phase, energy, power, power factor and other measurements. Current range: 0A ~ 10000A, corresponding to the output voltage signal, response band: 0.1Hz-1MHz, coil diameter is Φ100mm. The sensor uses advanced Rogowski coil technology, no hysteresis effect, almost zero phase error, no magnetic saturation, and high linearity. The coil part is free from any exposed metal conductors and is non-contact measurement method. The operation is safe and simple. It is small in size, light in weight, exquisite in appearance, flexible and flexible. It is suitable for narrow environments and densely packed places. Users can customize coil lengths according to their needs. , with integrator can be integrated into other test equipment, such as power quality analyzer, harmonic analyzer, power parameter recorder, phase detection analyzer, industrial control devices, oscilloscopes, high-precision digital multimeter, transient shock recorder , distributed measurement systems, protection systems, etc.
