Magnetic Circuit Design Studies for an Inductive Sensor.
Abstract
ONS TO BE USED IN ARTILLERY SHELLS AND THE RESULTS COMPARED WITH BOTH PRIOR AND SUBSEQUENT MEASUREMENTS MADE AT Harry Diamond Laboratories (HDL). The agreement of the calculated voltage vs velocity curves with those obtained experimentally is surprisingly good, the deviation in all cases falling well within 10%. For one of these configurations more precise computer calculations are done as well. These agree with our approximation procedure to within less than 3%. The approximate long-hand method is then employed to recalculate the output voltages expected if the Alnico 5 magnets presently used were replaced by Co5Sm. An approximately 50% increase in output is predicted for the two more efficient configurations while for the remaining case the effect of the replacement of material is, if anything, slightly deleterious. Various experimental tests of some of the underlying assumptions were made to verify as much as possible the general applicability of the techniques employed. (Author)
