Compact self-powered split core AC current sensors for energy monitoring and process automation. The split core opens and clamps around an existing cable without disconnection, with PRiME (Printed Rogowski Multi-coils) technology integrating sensing and signal conditioning in a single package for higher accuracy and simpler installation. Self-powered operation (loop-powered for 4-20mA output) eliminates the need for a separate auxiliary supply; 16mm diameter aperture; UL94-V0 plastic case.

Applications include process regulation via distributed PLCs and SCADA, load monitoring for protection and predictive maintenance on conveyors, pumps, and HVAC motors, and general AC current measurement in energy management panels.
