Flexible Rogowski Coil Current Sensor – Air-Cored AC Current Measurement
A flexible, air-cored Rogowski coil current sensor designed for accurate AC current measurement on large or irregular conductors. Ideal for retrofit monitoring, energy analysis, and industrial power measurement without breaking circuits.
The ProSense Flexible Rogowski Coil Current Sensor provides safe, non-intrusive measurement of alternating current using the Faraday electromagnetic induction principle. Unlike conventional iron-core current transformers, the air-cored Rogowski design eliminates saturation and allows accurate measurement across a wide current range.
Its flexible coil construction enables quick installation around busbars, cables, and conductors of varying sizes and shapes—making it particularly suitable for retrofit applications, crowded panels, and temporary measurements. The sensor outputs a proportional low-level voltage signal, allowing easy integration with power meters, energy analysers, data loggers, and protection systems.
With no internal power requirement and high immunity to magnetic interference, this sensor is well suited to industrial, commercial, and utility monitoring environments.
