Unit measures changes in diameter as small as 0.010 in., can sense virtually any material, and can handle any thickness of mate, rial. Sonatorq is suitable for any process that does not require a closed-loop, load-cell-type system.

* Varatorq--An inexpensive system that varies the torque of pneumatic clutches/brakes through a patented cam/lever arrangement. A follower arm rides on the diameter of a roll being unwound or wound and tracks the changing diameter, varying air-pressure to the clutch or brake. Adaptable to varying torque requirements and a wide range of air-pressure changes, the main shaft of the unit can be rotated clockwise or counter-clockwise for mounting on either side of the machine.
