The Rogowski coil current sensor operates based on the principle of electromagnetic induction to perform real-time measurement of large AC currents in power grids. It utilizes true RMS and linear compensation technology to isolate and convert the current into a standard DC signal output. Powered by a safe DC 24V supply, SUCH current sensor has high accuracy, strong electrical isolation, enhanced safety, and low power consumption. It is widely applicable in industries such as metallurgy, electroplating, and welding.
A Rogowski Coil Current Sensor is a non-intrusive, flexible, air-cored coil used to measure alternating current (AC). It works on the principle of electromagnetic induction, detecting the rate of change of current (di/dt) and outputting a voltage proportional to that change, which is then integrated to reflect the actual current.
It is designed to measure AC current only, including sinusoidal and non-sinusoidal waveforms (e.g., harmonics, transients, pulsed signals), making it ideal for modern power electronics.
