A sensor for measuring linear displacement has a core of magnetic material disposed for movement within a bobbin about which at least one coil of insulated, electrically conductive wire is wound. At least one Hall effect device is included in the sensor. The sensor is contained with a magnetic shell. When the coil is excited by a DC power source, the magnitude or direction of magnetic flux flowing through Hall effect device is dependent upon the position of the core.
