3.2 M OUNTING THE S ENSING R OLL
The following steps take into consideration the risk and difficulty of handling large rolls and help to minimize the
number of failed attempts at mounting the roll.
1. Before mounting the sensing roll, confirm that the transducer body is securely mounted.
2. Measure the roll shaft diameter, the shaft adapter bore diameter to be sure that they fit properly.
3. Loosen the two (2) set screws on the shaft adapter.
4. Place the roll shaft into the transducer adapter and tighten the setscrews per the torque specification in Table
“E”.
3.3 O RIENTING T HE C ANTILEVER T RANSDUCER
The Load Line on the transducer must bisect the angle of wrap. This is accomplished when the Cantilevered
transducer is oriented as shown in Figure 4 and 5. Rotate the transducer body until the proper alignment is achieved.
Generally a visual determination of this orientation is sufficient for most applications
The transducer is designed so that the cantilevered roller used for tension measurement provides the same tension
reading for a given web width no matter where the web is positioned along the length of the roller. For example, a 3
inch wide web riding on a 12 inch wide cantilevered roller produces the same tension reading whether the web is
centered on the roller or positioned left or right of center. The reading may deviate to a small extent if the alignment
is not exact. Optimizing or fine-tuning can be done if required. Consult the factory if you find this is necessary.
Once the transducer is properly oriented, Ensure that the transducer mounts are tightened the per the torque
specifications in Table “E”.

This alignment is very important to ensure that the Transducer reads the signal evenly across the whole
sensing roll.
