Abstract

1496134 Moving coil instruments HEALEY METERS Ltd 1 April 1975 [30 March 1974] 14236/74 Heading G1U A moving coil instrument having an annular outer polepiece 14 and an inner cylindrical polepiece 13 also includes means for adjusting the positions of the polepieces relative to each other to ensure a linear response for the moving coil 10, part of which 11 lies in the gap between the polepieces. After the adjustment has been made, by means of grub screws 23 bearing on a permanent magnet 20 between the polepieces, the assembly is stuck together with adhesive.
