The Rogowski Coil AC Current Sensor is a high‑performance, non‑intrusive current‑measurement solution designed for modern power systems, industrial equipment, and precision monitoring applications. By combining a flexible Rogowski coil with a dedicated signal integrator, the sensor delivers accurate, wide‑bandwidth AC current measurement with excellent linearity and minimal phase error.
The sensing element is a lightweight, air‑core Rogowski coil engineered for fast installation and reliable performance. Its flexible TPR body and compact 36 mm diameter allow easy placement around conductors in confined spaces without interrupting the circuit. The coil provides a stable output of 50 mV/kA at 50 Hz, supporting currents up to 2000 A with a wide frequency response from 10 Hz to 20 kHz. With ±0.2% linearity, ≤0.5° phase shift, and IP67 protection, it is suitable for harsh industrial environments and high‑accuracy measurement tasks.
The integrator converts the coil’s differential voltage signal into a standardized, proportional AC output. Operating from a 12 V DC supply, it delivers a calibrated 333 mV AC output corresponding to a rated 300 A input. The integrator features ≤1 μs response time, ±0.2% linearity, and a frequency range of 10 Hz to 10 kHz, ensuring faithful reproduction of both low‑frequency and dynamic current waveforms. Its compact suspended‑mount design and clearly labeled terminals simplify installation in control cabinets and monitoring systems.
Together, the Rogowski coil and integrator form a complete AC current sensor offering:
This combined sensor is ideal for power quality monitoring, inverter and motor drive diagnostics, industrial automation, energy management, and any application requiring reliable AC current measurement without disrupting the conductor.
