Gauss Meter Probe

Equipment

The sensing element of a Gauss meter, typically a Hall effect transducer mounted on a flat or axial probe tip. The probe is positioned at the measurement standoff distance from the coil face to capture the magnetic flux density at each scan point. Probe type (axial vs transverse), size, and positioning affect measurement accuracy. The probe model is documented in the report for traceability.

Gauss probes come in two shapes, and the shape sets which way the field must point to be read. A transverse probe ends in a thin flat blade and reads the field passing through the flat of the blade, so it is laid flat to the surface and can slip into edges and tight spots. An axial probe ends in a round rod tip and reads the field entering the end of the tip, so it is held along the axis and pointed straight at the surface. Either shape can measure the field at a surface or in the free space around a coil; the shape only changes how the probe is held to reach the spot.
