The
Hardy Instruments HI 3300 Tension Controller provides
precision control of winding, unwinding, and intermediate
zones in both web and strand processing applications.
The
Hardy Tension Controller incorporates an automatic
closed loop process to provide precision control
over the tension in the web or strand. The controller
incorporates either a single or dual sensor input
to allow for tension measurements on either web
rolls, or strand pulleys.
The
controller utilizes a PID algorithm to control
tension in unwind, rewind or intermediate zones.
The standard output from the Tension Controller
is 0-10V / 4-20 ma, which can be directed to a
brake or a drive. Hardy also provides pneumatic
systems to convert the analog output to a pneumatic
signal for air- brake operation.
Because
the actual product tension is measured, this type
of precision control eliminates common process
problems found in web and strand processes including
feathering, breakage, telescoping, wrinkling,
and blocking.
