FQ-RCT02 Flexible Rogowski coil 6000A AC current sensor

rogowski coil current sensor

The FQ-RCT02 flexible current sensor is an AC current sensor composed of a flexible Rogowski coil. The flexible current sensor permits measurements on conductors where standard clamp-on probes cannot be used. In particular, it can be installed in tight spaces, around cable bundles, around wide or large bus bars, or even wrapped around irregular shapes. It is suitable for large current measuring. They combine the benefits of a thin, flexible, clip-around Rogowski (sensor) coil with a signal conditioner providing accurate, true RMS measurement, of voltage output 100mV/kA.
