The 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
- 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.

Available in three outputs:
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 V, High Voltage output: Produces a standard variable voltage of up to 90Vdc to operate any electric brake or clutch, including eddy current clutches.
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.
