CATEGORY : CONTROLS FOR PRESSES Press Tonnage Modules The press industry has long recognizing the benefits of  load monitoring. The peak monitor module protects press from over and under tonnage, while the signature module acquires the tonnage and compares it to be within programmed limits from a reference signature curve. The reference signatures are learned by the module while few good parts are stamped. The Signature module can, in addition to protecting press from over tonnage, protect dies and ensure quality of stamped parts.
