The Hall Effect

Commercially we can find Hall Effect sensors both in their simple form and in bridge configuration. One of the advantages of using the bridged configuration is that it supports detecting field variations in both directions, simplifying the design of detector circuits. Hall effect sensors can be defined as being transducers that vary their output voltage in response to a magnetic field.

The operation of these sensors is based on the Hall effect. The effect of Hall determines that in a magnetic area traveled by a current which we will measure the voltage drop, we find that it will be zero volts. But when applying a magnetic field to this same area, a small voltage best prices for SKF-Bearing will appear between the two ends. The difference of these two tensions is due to the existence of a force to move the electrons along the magnetic area (Force of Lorenz). It is with the information of this potential difference that the Hall effect sensor acts. These sensors are generally best used for measuring rotor speed in electric motors and not in position.
