Rogowski coil RFSY Rated current 30A-500KA output voltage 50mV/kA@50Hz 60mV/kA@60Hz
The Rogowski coil also called a differential current sensor, is an "empty core" toroidal coil arranged around a conductor, so that the alternating magnetic field generated by the current induces a voltage in the coil. The coil is actually a current transformer coupled to the conductor under test, and the voltage output directly from the coil is proportional to the rate of change of the current.
For example:@50Hz/1kA Vout=85mV, @60Hz/1kA Vout=85*60/50=102mV.
If you want to obtain the current waveform or frequency independent current value, you need to add an integral circuit to achieve 90° phase shift compensation and frequency equalization.
RF series is a current sensor based on the principle of Rogowski coil. Its light weight and low price are available in different sizes, can also be ordered according to the customer's design requirements. No magnetic saturation and with a shielding layer, it resists the inf--luence of external magnetic fields, so stable measurements can be achieved from low currents to hundreds of kA. Provides accurate measurements in smart meters, industrial motor control and power monitoring applications.
Systems using an ADC chip (ADS131M04) that supports the Rogowski coil principle or a power metering chip (ADE7753) are more advantageous.
We offer integrators such as 4-20mA, 0-5V, 0-1A, 333mV for more use cases.
