Please note:The WebHandler3 Tension Controller has been discontinued. It has been superseded by the SteadyWeb5 Tension Controller which provides all the functionality of the WebHandler3 plus much more at a competitive price.
compact WebHandler™ 3 Tension Controller combines automated closed-loop
process tension control with an easy-to-use keypad interface. The WebHandler™
3 maintains a pre-selected tension set point on a web machine or press
by measuring web tension from a tension transducer, then sending a compensating
signal to a tensioning device such as a pneumatic brake, clutch or a DC
drive. This closed-loop capability improves process consistency and productivity.
Features include touch-pad setup and calibration, job setup storage and
recall, and LCD scroll-through of an array of simple-to-activate functions
including push-button rezero. The controller features soft start and bumpless
auto/manual switching. It also automatically compensates for speed changes,
roll diameter changes and other factors to maintain desired tension. Ten
different measurement units are available for expressing a tension reading
on the digital display.
