CSCA-A Series
Hall-Effect Based Open-Loop
Current Sensors
DESCRIPTION
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 this
core gap. Therefore, the HED output is directly proportional to
the amplitude and phase of the primary current.
The HED output is trimmed for gain and offset calibration such
that the CSCA-A Series sensor provides a predefined output
sensitivity versus primary current.
