AC Current Probe with Rogowski coil

FEATURES

APPLICATIONS

The RCP current probe is based on a rogowski coil which is small, lightweight and can be tied around conductors without breaking the current path. The current sensor is attached to the amplifier box, thus lacking the typical coaxial cable that usually clutters measurement setups. A version with a 20 cm pigtail between coil and transducer is also available, see picture in the “Ordering Codes” section.

▪︎ Coil attached to amplifier box or pigtail options▪︎ Rogowsky coil with 2MHz bandwidth transducer▪︎ 500A, 1000A, 2000A models, optional customisation▪︎ Low noise▪︎ Output BNC, user selects cable length▪︎ Battery powered, connects to any oscilloscope
