Abstract
In magnetic sensing apparatus having a pair of directional magnetic field sensors e.g. fluxgates longitudinally spaced apart in a containing tube (14), mechanical means is provided to compensate for misalignment in the sensor axes. The compensating means takes the form of a non-magnetic member (18) associated with one end of the tube (14) for rotation about the tube axis and a screwed plug (20) of easily magnetizable material contained in a diametrically extending threaded bore (24) formed through the rotatable member (18). Adjustments in the position of the plug (20) relative to the sensors e.g. (A) may thus be made by screwing the plug 20 inwardly and outwardly of the bore (24) to adjust the radial distance of the plug (20) from the axis of the tube and the orientation of the plug (20) relative to the sensors may be adjusted by rotating the member (18) in which it is contained relative to the tube (14). <IMAGE>
