In Mini Sigma-Nip from Sensor Products, the 168 microscopic sensor points that comprise each finger are densely packed within a 84mm active sensing area. The sensors capture data and record nip width readings while being viewed on a laptop or computer connected through wireless or USB. Adjustments to load are made in real time while the sensors are in the closed, (non-rotating) nip. Problems with alignment, skewing, and crown deficiencies are quickly exposed. The system is portable and the same sensor chain can be used to measure different sized rolls. Mini Sigma-Nip is useful for continuous maintenance, as well as during equipment setup and shutdown. Data that has been stored can be easily reviewed.
