Abstract

1502697 A position transducer METRAWATT GmbH 18 March 1976 [18 March 1975] 10982/76 Heading G1N A position transducer comprises a primary winding 2 connectible to a source of A.C., a ferromagnetic core 1 defining an air gap 3 in which a magnetic field is produced in response to a current flow in the primary winding 2, and an elongate flat secondary winding 4, 5 of which at least part is arranged within the air gap 3. The core 1 is rectilinearly displaceable parallel to the secondary winding 4, 5 and the width of the secondary winding varying so that the area of intersection of the secondary winding with the air gap varies in dependence upon the position of the core 1 relative to the secondary winding, whereby the voltage induced in the secondary winding during operation varies with the position of the core. In use the magnetic field in the air gap is substantially homogenous. As shown two triangular shaped windings 4, 5 are used. Alternatively a winding may be formed of a plurality of trapezium shaped turns, each turn being of a different length, Figs. 4, 5 (not shown) and the response being either linear (Fig. 4) or following a square law (Fig. 5). In a further embodiment the core is again U-shaped but the primary ending is carried by a U-sectioned member and surrounds one limb of the core, Fig. 6 (not shown). The secondary winding is on a circuit board which forms one portion of the U-sectioned member. Alternatively the primary and secondary windings may be carried on a circuit board, Fig. 7 (not shown), the primary winding being about a slot in which the bridge portion of the U-shaped core moves. In a yet further embodiment, Fig. 8 (not shown) the core is E-shaped the primary coil being carried by two circuit boards and surrounds the middle limb of the core. Each circuit board carries a secondary winding.
