Hall Probe Configurations
In “transverse” probes the Hall generator is mounted in a thin, flat
stem whereas in “axial” probes the Hall generator is mounted in a
cylindrical stem. The axis of sensitivity is the primary difference,
as shown by “
B ” in Figure 1-3. Generally transverse probes are
used to make measurements between two magnetic poles such
as those in audio speakers, electric motors and imaging
machines. Axial probes are often used to measure the magnetic
field along the axis of a coil, solenoid or traveling wave tube.
Either probe can be used where there are few physical space
limitations, such as in geomagnetic or electromagnetic
interference surveys.
Handle the Hall probe with care. Do not bend the stem or
apply pressure to the probe tip as damage may result. Use
the protective cover when the probe is not in use.
