Abstract

1512118 Measuring acceleration electrically PCB CONTROLS Ltd 21 July 1976 [19 July 1976] 30391/76 Heading G1N The acceleration or deceleration of a rotating metal disc 1 is measured by the e.m.f. induced in a coil 4 by the change in flux produced by the eddy currents developed in the disc by two permanent magnets 2 located near the periphery of the disc on either side of the coil 4, which is wound on a laminated core 3.
