INDUCTION LINEAR DISPLACEMENT SENSOR Russian patent published in 2016 - IPC G01B7/00 G01D5/22 

FIELD: test and measurement equipment.

SUBSTANCE: invention relates to instrumentation and can be used, in particular, in control system of electrohydraulic and electromechanical drives of aircraft. Summary: sensor has coil consisting of two measurement windings and excitation windings wound on frame from nonmagnetic material, core made from magnetically soft material, which is connected mechanically to controlled object by means of nonmagnetic rod. Each of measuring windings is stepped throughout length of frame and has two rows of wire coils wound evenly along whole length. Excitation winding is wound on top of measuring windings. Measuring windings are made according to differential circuit.

EFFECT: technical result is reduction of dimensions of the sensor, possibility of accurate adjustment of steepness of output characteristics, elimination of errors caused by output characteristic oscillations of supply voltage sensor.
