Hall effect sensor
Videos
A Hall effect sensor is any sensor based on the Hall effect, in which a voltage is produced proportional to one axial component of the magnetic field vector B.
Engine fan with Hall effect sensor
Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply voltages that maintain a 4 to 8-volt differential. The non-zero current response is proportional to the voltage supplied and is linear to 60 amperes for this particular (25 A) device.
