The CSCA-A Series of open-loop current sensors are based on the principles of the Hall-effect wherein a Hall-effect device (HED) produces an output voltage linearly related to the amplitude and phase of a magnetic field applied to it.
Current flowing through a primary conductor generates a rotating magnetic field around the conductor. This field is
collector by a core of magnetically sensitive material and concentrated in the gap in this core.
The HED is located in thiscore gap. Therefore, the HED output is directly proportional tothe amplitude and phase of the primary current.The HED output is trimmed for gain and offset calibration suchthat the CSCA-A Series sensor provides a predefined output sensitivity versus primary current.
