ELECTROMAGNETIC DISPLACEMENT TRANSDUCER Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: displacement transducer has two cores which are turned one to the other with their rods and mounted in a spaced relation one relatively the other. Windings are disposed onto the rods; the windings are connected in series aiding. Rectangular-section permanent magnet is attached between edges of end rods of both cores. The other pair of end rods is separated by air spaces from movable object under control, which is made in form of ferromagnet gear. Maximal value of this space is less than value of space between average rods of both cores. EFFECT: improved precision. 3 cl, 2 dwg
