ABSTRACT:
A compact linear transducer assembly including a Hall effect semiconductor material, which material generates a variable voltage as a result of displacing an array of gratings, formed in a first, highly permeable magnetic plate, in a magnetic field relative to the Hall effect material and to a corresponding array of gratings, formed in a second, highly permeable magnetic plate. A counter is responsive to the voltage across the Hall effect material to provide an indication of the linear distance traveled by the movable grating plate.
