2.1 SELECTION OF TRANSDUCER
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 that
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 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
damaged the Transducers and void the warranty.

Instructions for Mounting the UPB Load Cell to
the Machine Frame (see Figure 6)
Remove the pillow block mounting plate (it is held
in place by four stainless steel corner bolts) in order
to gain access to the four load cell mounting holes.
Drill and tap the machine frame to match the load
cell mounting holes (refer to section 2.5 to properly
position the load cell). Bolt the load cell in place.
The UPB load cell is designed so that either
imperial or metric mounting bolts can be used when
mounting the load cell to the machine frame. Refer
to E in the Figure 2 above for the proper bolt size.
Before remounting the pillow block mounting plate,
refer to section 2.6.

2.5 POSITIONING THE TRANSDUCER
Once the four tapped holes have been drilled, you
need to orient the UPB load cell properly to obtain
PRECAUTION
Always install, orient and firmly bolt
down the transducers BEFORE
installing the tension-sensing roll. When
disassembling or installing, DO NOT
remove the transducer and the tension-
sensing roll as an assembly - remove the
roll first, before loosening the transducer
mounting bolts.
