FIELD: check of linear travel of objects in various engineering fields. SUBSTANCE: magnetic circuit of sensor has of flat Ф--shaped frame. Central transversal rod of magnetic circuit has two sections of measuring winding and extreme transversal rods have one section each. Longitudinal rods of each port of magnetic circuit are cut by inclined straight or broken lines. Sensor is provided with two electromagnets with field windings and pole shoes. Movable electromagnets are located across longitudinal axis of sensor; they connect longitudinal rods of each port of magnetic circuit. When electromagnetic move along axis of sensor, magnetic flux, via sections of measuring winding, changes according to linear law or stepwise. When field windings are connected in parallel and sections of measuring winding are connected in pairs in series and in opposition, sensor may be used for measuring parameters of two objects simultaneously. EFFECT: enhanced of measuring. 2 dwg
