WebHandlerTM 3 Digital Tension Controller
Panel Mount option
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.
Now available as a Panel Mounting device. This version of the WebHandler3 installs quickly and easily onto
OEM machinery or as a retrofit on an existing machine. The unit mounts into a
small rectangular cutout on a web machine frame or control station and is secured
by bolts at the front panel corners.
Version P, Pneumatic output: Actuates any air operated
brake or clutch. The standard version includes a servo valve and pressure
regulator installed in an open back enclosure.
Version D, 0-10Volt
DC compensated output module:
Controls DC drives or other variable speed drive systems. This output
is isolated from earth ground to make it more compatible with all drives.
