Patent ID: 7614306

Claim:
A stress monitoring system for use in a vibrating unit comprising: a vibrating unit including a first sidewall plate, a second opposing sidewall plate and at least one screen deck transversely mounted between said first and second sidewall plates, said first sidewall plate including at least a first monitoring point and said second sidewall plate including at least a second monitoring point, wherein said monitoring points are located at corresponding locations on said first and second sidewall plates; at least two motion sensors corresponding respectively to the x and y-axes disposed at each of said first and second monitoring points on said first and second sidewall plates, each of said at least two motion sensors being configured to monitor movement in one orthogonal axis; said at least two motion sensors on each of said first and second sidewall plates being connected to a processor such that simultaneous monitoring data of said first and second monitoring points in both said x and y-axes is provided to said processor for comparing real-time movement of said first and second monitoring points on said first and second sidewall plates.
