1. Principle of Transducer Operation

Cleveland Kidder web tension transducers utilise a sensing beam to which semi-conductor strain gauges
are bonded and are used for non-rotating shaft applications. Normally a pair of transducers would be
used, supporting the ends of the sensing roller shaft. The tension force applied to the sensing roller must
pass freely through to the transducers, which convert this force into an electrical signal.
This signal is a combination of tension force and sensing roller dead weight. The dead weight of the roller
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. Installation

2.1

Selection of Transducer Mounting Location

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.
