TENSION CONTROL
SONA-TROL is an efficient and low cost system for controlling
tension and determining unwind and rewind diameters.
SONA-TROL Diameter measurement systems can be used to compliment
load cell based tension control systems.
SONA-TROL Replaces diameter and ratio calculators and provides
superior accuracy and provides diameter information at zero speed.
SONA-TROL combines sonar principles and technology with state of the
art digital and analog electronics.
SONA-TROL is unaffected by material inconsistencies, dirt, lint and
variations in line voltage.
SONA—TROL replaces electromechanical follower arms and diameter
calculators. Tension is controlled precisely from the point where
the material comes off a roll to ensure constant tension despite out
of round rolls.
