Answer / kumar

proximity probe tip is wound on coil if any damage in tip won't get reading. proximity probe installed in -6v gap voltage didn't get proper microns because that time magnetic flux line is not created fully so we installed probe in -10v this time probe 200 microns/mills or 100 microns/mills we get exact variation in probe
