The CP9000 SA, A and LA series flexible current probes (Rogowski coils) measure AC current with high bandwidth and typical 2% accuracy. Ranges run from 30 A peak to 3000 kA peak and frequencies from a few Hz to tens of MHz, covering both small-signal switching currents and very large pulsed currents.
The light, flexible coil can be opened and wrapped around conductors that rigid probes cannot reach, with almost zero insertion loss. The SA series has a very thin coil for tight spaces (up to 30 MHz), the A series a 200 mm ring (up to 15 MHz), and the LA series a 600 mm ring for very high currents with 1% accuracy. Ring size, range and cable length can be customized.
