Product Description

Product Description

Introduction to Rogowski coil

Rogowski coil also called differential current sensor, it is a "hollow" circular coil, arranged around the conductor, so that an alternating magnetic field generated by the current induces a voltage in the coil. The coil is actually a transformer coupled to the conductor under test, and the voltage directly output from the coil is proportional to the rate of change of current, e.g. @50Hz/1kA Vout=1000mV,@60Hz/1kA Vout=1000*60/50=1200mV. If you want to obtain the current waveform or current value that doesn't matter to frequency also need to add the integral circuit to achieve 90° phase shift compensation and frequency equalization.

The RHS series is a rogowski coil-based current sensor with different sizes available for light weight and low price, or can be ordered specifically according to the customer's design requirements. Non-magnetic saturation and shielding protect against external magnetic fields, resulting in stable measurements from low currents to hundreds of kA.Accurate measurements are available in smart meters, industrial motor control and power monitoring applications. Systems that use an ADC chips(ADS131M04) or a power metering ICs(ADE7753) that support the Rogowski coil principle are even more advantageous.
We provide 4-20mA, 0-5V, 0-1A, 333mV and other integrators suitable for more usage scenarios.

Dimensions and Diagram

Notice:

1. According to the Rogowski coil principle, the output voltage is directly related to the

conductor (di / dt) of the input current.

2. The output voltages are sine waveforms of a constant rated frequency in Hz and are measured

at RMS values.

3. Vout (RMS) = Amps (RMS) × Hertz×K×10-6, where K depends on the manufacturer, 1000mV

model K value is 20.

Warning:

Do not apply pressure to the coil by any form of mechanical force (e.g., twisting, piercing, excessive pressure, excessive bending, etc.), which will reduces the accuracy of the device greatly
