Аннотация:Wheatstone bridge (WB) network output signals are considered for different bridge sizes, numbers of sensitive elements, and orientations with respect to the label. We demonstrate that the WB output signal, strongly depends on several factors. First, the height and width of the signal strongly depend on the position of the line of motion with respect to the geometry and orientation of the label. The design and parameters of the WB sensor is a second factor. A third factor is the orientation of the WB sensor with respect to the magnetic field of the label.
