RCT Rogowski Sensor Range

Industrial Rogowski Coil Current Sensors for Permanent Monitoring and Control Installations

The RCT range is a family of industrial current sensors based on Rogowski coil technology, designed for permanent or semi-permanent installation, measuring AC currents from 250Arms to 50kArms. The RCT range provides a reliable, flexible and lightweight alternative to traditional current transformers, featuring industry-standard outputs and typical accuracy better than 1% across its operating range.

Select models—including the RCTi, RCTi-3ph, RCTrms, RCTrms-3ph, and the robust RCT1A—offer excellent performance characteristics with <1 degree phase shift at 50/60Hz to 1kHz. The RCT electronics come as either DlN rail or panel mount, and cover rated currents from 100A to 50kA. They have industry-standard outputs including 0-5V ac, 0-1A ac, and 4-20mA dc options.

Use the selection filters below to identify the optimal RCT sensor for your permanent installation requirements—quickly and efficiently.
