Flexible Rogowski Coil Current Sensor 100kA 333mV 21cm

Flexible Rogowski Coil Current Sensor for 10A to 200kA Measurement This flexible Rogowski coil current sensor is designed for alternating current measurement across a wide range of applications. With a measurement span from 10A up to 200kA, this versatile sensor accommodates a broad spectrum of current sensing needs, making it suitable for both light industrial and heavy-duty electrical installations. The coil features a 21cm flexible loop that can be easily wrapped around conductors or busbars without the need to disconnect the circuit, simplifying installation and reducing downtime during setup. This flexibility also allows the sensor to fit around awkwardly shaped or confined conductors where rigid current transformers would be impractical. Output Options and Signal Compatibility This particular unit provides a 333mV output at 100kA, offering a proportional voltage signal that interfaces cleanly with most metering, monitoring and protection equipment. The sensor is available with alternative output configurations including 0.33V, 0.5V, 1A and 4-20mA variants, allowing you to match the signal type to your existing instrumentation infrastructure. The sensor operates on the Rogowski coil principle, which is well suited to applications involving large variable loads and motor starting currents. Construction and Practical Use The flexible design uses a lightweight, durable construction that remains stable over extended periods of use. The 21cm coil circumference provides a practical opening for most cable and busbar arrangements, while the sensor body is designed to withstand the rigours of routine industrial service. Typical applications include power monitoring, load profiling, energy management systems, protective relaying and general electrical testing. The sensor connects easily to standard measurement equipment, and the output signal can be fed directly into data loggers, panel meters or control systems for continuous monitoring.
