TheDENT RoCoil™Current Transformers have been designed for accurate non?intrusivemeasurement of AC current, pulsed DC or distorted waveforms. Thistype ofsensormay be used to measure AC current over a wide dynamic range and from40Hz to 5 kHz.Note: The RoCoil™may require use ofintegrator/ ampli?er. See also RoCoil mV™.
