Hakk effect gauss meter practice

[cataldo]

Hi everybody... I am studying the theory hall sensor for magnetic particle testing...It is a usually techinque non destructive for aeronautic application..In one paper i have read "the hall sensor respose is proportional to the sine of the angle between B and the plane of the hall sensor"..The question is: i do not understand what angle... If is possible to attachment a picture for explain it...

The Hall Effect sensor produces a very small voltage (often less than a millivolt per Gauss) for a magnetic field that is usually perpendicular to the large area of the sensor. See datasheet for details. I guess this might be for a magnetic compass in aircraft.
There are "raw" 4-lead Hall Effect sensors (like a Wheatstone bridge), and "regulated" Hall Effect sensors. Here is the datasheet for the AD22151 sensor from Analog Devices:

Here is a list from Allegromicro:

tanks for your replay...Very interesting
