Title: LINEAR SELSYN OR SYNCHRO-TRANSMITTER

Abstract

An apparatus is patented for determining the position of a member movable axially within a closed tube without perforating the tube. A magnetic core, short with respect to the length of the member, is mounted thereto. A coil and a plurality of windings are disposed axially outside the tube and have a total uniform circumferential progression of 360 mechanical degrees or a multiple thereof relative to each other as they extend the length of tube. The coil and windings are electrically excited whereby axial movement of the magnetic core induces therein voltages having magnitudes or phase angles proportional to the axial position of the magnetic core within the closed tube. Detecting means are provided for reading the magnitudes or phase angles of these voltages and hence the position of the movable member within the closed tube.
