ABSTRACT:
The inductance of a coil wound on one end of an elongated rectangular core with an elongated central window is caused to vary by the displacement of a conducting plate or ring arrangement lengthwise of the core. The other end of the core may also be wound with a coil to produce a differential type of transducer. The elongated core may be bent around into a circle in order to provide a transducer for rotational displacement. Additional ferromagnetic bodies in fixed relation to the core or to the short-circuiting rings can be used to modify the translation characteristic.
