GT Caliper sensor

GT Caliper features advanced patented Gliding Technology. This technology is the result of extensive research and development of materials which provide low density, extreme durability and an aerodynamic design with dirtrepelling qualities. 

The sensor features unique sensing planes that smoothly glide across the paper web for superior measurement and non-marking performance. GT Caliper is the most responsive, accurate and reliable sensor in the industry. It combines high signal-to-noise ratios, sub-millisecond response time and high resolution for a better-than-laboratory accuracy.

To accommodate today’s advanced spectral analysis, GT Caliper provides users with a combination of response and resolution that is a ratio of 100:1 better than conventional equipment. When utilized in combination with commercially available machine health monitoring and process diagnostics packages, it provides unmatched diagnosis and optimization of calendar operations. The sensor works with CD Caliper Controls and the ABB Induction xP Calender Profiler or other caliper actuators, to automatically correct profile deviations. Improved runnability, fewer sheet breaks and reduced off-spec paper are the bottom-line results of accurate measurement and precise control.

GT Caliper operates with the ABB Quality Control System for a complete, integrated solution. In addition, it can integrate with a mill’s existing supervisory and distributed control. This integrated and open approach demonstrates ABB’s commitment to helping you optimize your process while maximizing your return on capital investments.
