How much is the radial vibration, if the signal measured on a DVM is 135.00mv AC

Field Instrumentation
1

The DVM measures the AC voltage in RMS (root mean square value). AC peak to peak =135.002 root 2 =181.837mv Eddy probe sensitivity=200mv/mill or 200mv/25.4 Microns Hence, the vibration in Micron =(381.83725.4)/200 =48.49 Micron
