Abstract
A detection system is installed into a press piston guiding area for detecting if the piston guiding system has lost its requisite clearance. The detector is installed in a typical press in such a way that when the negatively grounded press piston touches the detector, it discharges the electrical potential between the detector and the piston. Upon contact, a signaling device stops the press, and a fault is indicated. In an alternative embodiment, the detector senses an eddy current when in close proximity to the piston.
