Product Characteristics
1. Measurement of AC current、higher harmonic current 、complex waveforms current、transient current
5. Line Voltage: Below 600V
6. CT Structure: Rogowski coil
7. Material Coil Diameter : φ7.5mm/φ12mm(Optional)
ETCR001F Flexible Coil Current Sensor(with Integrator), suitable for a large range of AC current, high harmonic current, phase, energy, power, power factor and other measurements. Current range: AC 0A~3000A/6000/10000A(Optional), corresponding to the output 0 ~ 1V (another gear range: 0A ~ 300A, corresponding output 0 ~ 1V) Response frequency 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 flexible coil is the differential of the current vs. time, and the integrator integrates the output voltage signal (0~1V) to truly restore the measured current and output a complete signal waveform. 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 length according to their needs. , can be integrated into other test equipment, such as power quality analyzer, harmonic analyzer, power parameter recorder, phase detection analyzer, industrial control device, oscilloscope, high-precision digital multimeter, transient shock recorder, distributed measurement System, protection system, etc.
