2.1 SELECTION OF MOUNTING LOCATION
When selecting a transducer mounting location,
keep in mind that the tension sensing roll must
NOT be mounted where the web wrap angle can
vary. Any change in the wrap angle will be sensed
by the transducers as a change in tension, and
indicated as such on the tension indicator.
Figure 3
In some cases, it may be impossible to find a
location for the transducers where the wrap angle
does not vary. The change in indicated tension
which will result can be calculated and, if small,
may not be significant.
2.2 MOUNTING SURFACE PREPARATION
The mounting surfaces for the transducers should
be flat and parallel. Prepare the machine frames or
mounting surfaces by removing any loose paint,
rust, scale, etc.
2.3 GENERAL INSTALLATION INFORMATION
The transducers must be mounted so that the
applied web force is approximately perpendicular
to the solid half of the shaft supporting socket.
See Figure 4 and the instructions on page 8 for
your particular transducer type and orientation.

2.4 INSTALLATION PRECAUTIONS
To insure proper installation and operation of the
system, the following steps should be performed
in sequence. Failure to do so could seriously
damage the transducers and void the warranty.
PRECAUTION:
Always install, orient and firmly bolt down
the transducers BEFORE installing the
tension sensing roll. When disassembling
and installation, DO NOT remove the
transducer an the tension sensing roll as
an assembly - remove the roll first, before
loosening the transducer mounting bolts.
DO NOT rotate transducers (for
orientation) with the tension sensing roll
installed. Damage may result.
