Hall
Current Sensors – Open Loop
The Hall Current sensors measure the
magnetic field surrounding the conductor (also sensing DC currents).
A circular core of soft magnetic material is placed around the
conductor to concentrate the field. The Hall element, which is
placed in a small air gap, delivers a voltage that is proportional
to the measured current.
Open Loop Current Sensors are more
affordable than Closed Loop Current Sensors, but the amplified
output signal of the Hall element is directly used as the
measurement value (resulting in a lower sensitivity). The linearity
depends on that of the magnetic core. Offset and drift are
determined by the Hall element and the amplifier.
