Power System Sensor

The OFLS series Rogowski Coil is used for electronic measurement of AC current. The error due to the position of the measured conductor within the aperture and the error due to the proximity of the external conductor are greatly reduced using magnetic shielding techniques.
It has the advantages of fast response, small volume, small power consumption, frequency response width, anti-interference, lightning wave and shock wave protection.

Rogowski Coil is a current transformer fixed by cable ties based on Rogowski principle, particularly suitable for measurement in combination with portable devices.
Due to its specific features, Rogowski coil is an extremely comfortable solution for current measurement and can be used in a number of cases where traditional current transformer is not the adequate solution.
OFC-150-305C1 is Calibrated type, with connector GX12-2P female
