INSTALLATION
SELECTION OF SENSOR MOUNTING LOCATION
NOTE
When selecting a sensor mounting location, keep in
mind the tension sensing roll must NOT be mounted
where the web wrap can vary. Any change in wrap
angle will be sensed by the sensors as a change in
tension and indicated as such on the indicator.
MOUNTING SURFACE PREPARATION
The mounting surfaces for the Tension Sensors should be flat
and parallel. Prepare the machine frames or mounting surfaces
by removing any loose paint, rust, scale, etc.
TENSION LOADING DIRECTION
The Tension Sensors must be mounted so the applied
web force is approximately in line with the cable connector
(Figure 3).
