Predictive maintenance is usually defined as monitoring performance and condition of equipment during normal operations. This implies that simply providing a highly efficient, reliable and small enough to integrate vacuum ejectors is no longer enough. Vacuum ejectors powering robotic gripping systems such as suction cups, foam grippers etc. for pick and place applications common e.g. in automotive press shops are the interconnection between the gripping unit and the robot and can provide insights into both sides to ensure a smooth-running system.
