Nip Analysis System

Published November 30, -0001
Sensor Products Inc. has introduced Sigma-Nip, a technologically advanced electronic nip analysis system that measures roller profiles and diagnoses roll alignment with unprecedented speed and cost-effectiveness. This sensor system, which records nip width, renders obsolete time-consuming and inexact tools such as carbon paper and embossed foils. When Sigma-Nip is used, loading problems, skewing, and crown deficiencies are quickly exposed. It is more accurate, more durable and has a more powerful software user interface than any of its predecessors.

Sigma-Nip consists of a chain of sensor elements and Windows-based software. The new sensors have been improved to withstand repeated high pressures and temperatures as well as routine exposure to grease and solvents. When placed between two contacting rollers, the sensors capture data and ultimately record and assimilate nip width readings on a laptop while it is being viewed. Adjustments to rollers are made in real time while the sensors are in the closed (non-rotating) nip.
