Abstract

968,275. Moving coil instruments. SANGAMO WESTON Ltd. Feb. 2, 1961 [Feb. 2, 1960], No. 3701/60. Heading G1Q. A moving coil measuring instrument includes a magnetic system comprising a permanent magnet 11 located within a one piece pole shoe 14 which is substantially cylindrical and is rigidly secured to the magnet, the assembly being located within the moving coil which operates in the gap between the pole shoe and a surrounding yoke ring 25, the magnet and pole shoe being held in position within the yoke ring by means of diametrically opposed key members 21, 22 located in axially directed slots. The key members are U-shaped (see Fig. 2), non-magnetic and locked into position by means of a locking block 23 and screw 24. This assembly is held clamped between two bridge members which carry the pivot mountings and spring securing arrangements for the coil, and the whole arrangement is contained in a moulded insulated casing having special ledges and projections for mounting the instrument (Fig. 7) and held in position by set screws. Rubber buffers may be included if the instrument is to be used under conditions of violent shock. Specification 838,056 is referred to.
