Encoders For Pulp & Paper Mills

Speed, precision and control are critical in the fast-paced pulp and paper industry. Northstar offers a wide range of heavy-duty encoders and mill-duty magneto-resistive encoders designed to meet the performance and environmental extremes of the pulp and paper mills industry including Northstar brand RIM Tach® Series encoders.

Our comprehensive line of digital control systems provides reliable speed and web tensioning control for reliable plant operation. These rugged, standardized and customized digital encoders are engineered with magneto-resistive technology to track machine speed for precise control in the harshest of environments.

Our Mill-Duty (RIM Tach®) encoders provide reliability and precision even under the most challenging conditions and provide solid signals to precisely track machine speed for better control and for trouble-free and trustworthy performance. Our Heavy-Duty (Slim Tach®) encoders incorporate a bearingless and ultra-thin design for longer encoder life and a variety of motor mounting possibilities.
