Transducer and Sensing Roller Installation

The transducer should be mounted so that the Measurement Direction is in the direction of the resultant

tension force. The cable connector is at right angles to the Measurement Direction.

One end of the sensing roller should be held in the bearing of one transducer, as at 'A' above; the other

end of the roller must be free to move or "float" axially in the other transducer bearing, as at 'B' above.

This float must allow the overall distance between transducers to be reduced by at least 8mm to permit

the transducers and roller assembly to fit inside the machine frames for installation. The transducers may

also be fitted on the outside faces of the frames to allow full use of the machine width. Alternatively

provision must be made to fit the complete transducers and roller as an assembly into the machine

axially. The bearing is retained in the transducer by circlips. It is recommended that only the plain side

plate "A" of the transducer be removed for bearing access, see the Transducer Dimension drawing for

details.

2.7

The transducer is supplied with a temperature compensation network which is in series with Pin D, the

output signal lead. The compensation circuit will operate correctly only when used with a tension indicator

or controller supplied by CMC Controls. The transducer can accommodate sensing roller shaft expansion

due to normal temperature changes. The transducer, sensing roller and machine structure should all

therefore be at normal room temperature during installation
