The purpose of the system is to control the roll pressure (position) based on the incoming board/cant thickness. The Pneumatic Positioning System utilizes a Royal TR Series designed pneumatic actuator with integrated Temposonics probe for position feedback.

This is an economical solution for driving pneumatic cylinders moving rolls in closed loop control. This positioning system is also used on pickers and side rolls. The system is comprised of:

• Controller Board
• Proportional Valves
• Temposonics Probe integrated into the Royal Cylinder assembly
• Linear Displacement Optical Lasers
• Interface
