Topaq Measures Nip Roll Contact Pressure

Sensor Products Inc., East Hanover, N.J., developed its Topaq® Pressure Analysis System for use in
conjunction with Pressurex®/Fuji Prescale® stress-indicating films to measure and interpret
pressure between contacting or impacting surfaces. The Microsoft® Windows®-based system is suitable
for research and development, and quality control applications such as measuring nip pressure and
roll contact pressure in coating machines.Topaq scans and interprets the exposed Pressurex/Fuji
Prescale film, which changes color in proportion to the amount of applied pressure. The film aids
in calculating uniform loading in the cross direction of a press and ensures that nipped rolls
remain parallel during roll changing and routine downtime.
