MEWOI-A Series Rogowski Coil Current Sensor/Transformer/Transducer

• Wide application environment: special flexible material making, convenient measurement of conductor current in any special environment

• Fast response, no saturation, and good precision, small angle difference: due to the unused iron core, the corresponding fast and unsaturated effect, the measurement accuracy is high, and the phase shift is small.

• The range of current measurement is wide: from 50mA to 200kA (power frequency range)

• The output interface is easy to match: the output interface can be conveniently connected to the oscilloscope, the multimeter, the power meter and other measuring or on-line monitoring equipment.

• Wide frequency range of measurement: Measurable current frequency bandwidth 2Hz-2Mhz(-3dB)

• Current measuring gear adjustable: current measurement is divided in o three levels, can be realized on the current measurement accuracy, accuracy 1%.

• Safety: it is safe and reliable compared with the conventional current clamp, which has not two-times-opening danger, especially when large current is tested.

• Coils length, output voltage and other parameters can be customized according to customer requirements
