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. _____________________________________________________________________________________________________________________ Absolute Measurement Ltd.

To ensure that this problem is avoided, the critical roller speed should be at least 20% above that attained at maximum web speed. Consult the roller manufacturer for advice. _____________________________________________________________________________________________________________________ Absolute Measurement Ltd.

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 _____________________________________________________________________________________________________________________ Absolute Measurement Ltd.

If the display decreases or moves negative, reverse the appropriate yellow and green transducer leads at the indicator terminals. Repeat for the other transducer. When completed, reconnect both transducers. _____________________________________________________________________________________________________________________ Absolute Measurement Ltd.

Page 7: Transducer Force (Mwf) Calculation
There may be a high degree of misalignment of the transducers causing a severe pre-load. The sensing roller weight may be too heavy, this should not exceed the MWF of the transducer. _____________________________________________________________________________________________________________________ Absolute Measurement Ltd.

Check that one end of the tension sensing roller is free to float axially in the transducer bearing. Transducer Strain Gauge Resistance The transducer has four foil strain gauges in a Wheatstone bridge. The nominal resistance is 350 ohms. _____________________________________________________________________________________________________________________ Absolute Measurement Ltd.
