The basic SV3X balancing package consists of the SV3X, a four channel pigtail BNC adapter cable, phase reference marker, two single axis accelerometers with cabling to BNC connectors, reflective tape for marking the shaft and balancing software. The balancing system is a robust package which provides a convenient means for balancing any rotor type. It can simultaneously track up to two planes with constant monitoring of rpm, amplitude and phase. It can determine running speed to within a hundredth of an rpm, measure amplitude with better than 80 db of dynamic range and phase to within a tenth of a degree or better. It can also track speeds from 20 to 60,000 rpm and faster, depending upon the phase reference marker selection.
