Abstract
A phase angle monitoring apparatus for phase monitoring a vibratory system includes a controller that produces a phase angle control signal representative of the lead or lag between the vibratory movement of two vibrating masses. The phase angle control signal is coupled to at least one of the vibrating masses to adjust the vibration of the mass to produce a desired phase angle, for example one-hundred eighty degrees (180°).
