Multi-Zone Web Tension Transmitter: Model LCt-104
LCt-104 Tension Transmitters measure up
to four independent web points, or zones,
to ensure maximum operating speeds without
belt, felt, or product breakage. Each
zone is precisely measured with 750,000
count resolution and produces a corresponding,
high resolution, 4-20 mA output.
Total, individual, and differential outputs
from two HTU transducers permit a comparison
of tension signals on either side of
a sheet, strip, or web.
Digital calibration eliminates time consuming
dead weight loading and machine
‘strapping’.
With four integral operating modes,
LCt-104 transmitters offer wide operating
flexibility and easy installation. Simply select
the mode that matches your application,
enter the transducer zero and span
values, and begin system operation.
When combined with HTU transducers,
units measure both horizontal and vertical
tension vectors. Based upon both measurements,
software algorithms calculate
the precise, resultant force vector and exact
linear tension component. Auto-wrapping
maintains smooth, constant tension
for winding zones as the roll diameters increase
or decrease.
