Abstract:
A magnetic sensor comprising:a support extending outward from a base to a distal portion;a beam fixed to the distal portion and extending inward therefrom to a free end of the beam adjacent the base;a pair of matched magnetic sensing elements carried by the base and spaced one from the other by a predetermined distance, the base and elements being fixed in spaced adjacency opposing the free end of the beam such that the free end of the beam occupies a substantially equidistant, nominal position relative to both elements;magnetic field means disposed against the magnetic sensing elements and at the free end of the beam; andsaid free end of the beam being connected with the base through the beam and the support whereby force applied against the beam causes resilient displacement of the free end from the nominal position; anddriving means coupled to the sensing elements such that a differential signal is generated between the sensing elements indicating the various positions of the free end of the beam for conversion to operational data.
