1. Principle of Transducer Operation

ACDF web tension transducers are annular force transducers supplied with double row self-aligning ball

bearing cartridges for rotating shaft applications. Normally a pair of transducers would be used,

supporting the ends of the tension sensing roller shaft. The tension force applied to the sensing roller

must pass freely through to the transducer, which converts this force into an electrical signal.

This signal is a combination of tension force and sensing roller dead weight. The dead weight is zeroed

out electrically in the indicator or controller leaving the tension force signal only to be amplified to give a

true display of measured tension.

2.1

The transducer must be mounted in a clean, dry location, see below for hazardous area installation.

When selecting a transducer mounting location, please remember that the tension sensing roller must

NOT be mounted where the web wrap angle can vary. Any change in the wrap angle will be sensed by

the transducer as a change in tension, and indicated as such on the tension meter or display.
