We have a 3500 bently nevada system in BFPT for boiler for 700 mw STG. The main pump rotate at 5480 RPM The gap voltage is set at -11V DC for bearing DE end of pump.
Due to setting at -11vdc instead of -10 vdc it will make any difference in radial vibration measurement (dynamic value)? I want to know that it will give erratic reading or not, and if any then how much?
