ABSTRACT:
Displacement measuring apparatus for measuring the displacement and movement of an object includes an array of sensors having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the disposition of an electrical/magnetic field producing member along the sensor array. The field producing member is disposed to contact and slide over the operative surface as the object whose displacement is to be measured is moved. The value of the electrical output signal produced by the circuitry is thus dependent upon the position of the field producing member along the sensor array and thus by the position and movement of the object.
