ULTRA SERIES SLIM CELL TRANSDUCER 1.4 AO-70263 REV AA PRE-INSTALLATION PRECAUTIONS 1.4.1.1 SHIPPING Shock and vibration transmitted to the transducers by the sensing roll during transportation can damage the transducers. It is essential that you remove the sensing roll when the machine is shipped with the transducers mounted. 1.4.1.2 ROLL BALANCE The sensing roll should be adequately balanced.
ULTRA SERIES SLIM CELL TRANSDUCER AO-70263 REV AA 2 GENERAL DESCRIPTION The Ultra Series Slim Cell Transducer utilizes a twin sensing beam. Conversion from mechanical strain to an electrical signal is accomplished using semiconductor-based, piezoresistive strain gage MACHINE FRAME elements. The Full Wheatstone Bridge configuration provides an electrically balanced output yielding twice the amount of signal swing as half-bridged transducers operated at the same excitation voltage.

ULTRA SERIES SLIM CELL TRANSDUCER AO-70263 REV AA 2.2.4 SELECTING A MOUNTING LOCATION Select the mounting location for the transducer keeping the following points in mind: • The transducer can be mounted to either inside or outside of the machine frame. • The tension-sensing roll must not be mounted where the web wrap angle can vary, or the transducer will not interpret the tension properly.
ULTRA SERIES SLIM CELL TRANSDUCER AO-70263 REV AA 3 INSTALLING THE SLIM CELL TRANSDUCER 3.1 INSTALLATION PRECAUTIONS To ensure proper installation and operation of the system, keep the following points in mind: • Do not apply shock loads to the Slim Cell bearing assembly when mounting or dismounting rolls. • Exercise care to avoid overstressing the transducer when handling partially mounted rolls. Even relatively short rolls can afford an impressive mechanical advantage over the transducer.
ULTRA SERIES SLIM CELL TRANSDUCER AO-70263 REV AA 3.3 POSITIONING THE SLIM CELL TRANSDUCER Use the following step when positioning the transducers for mounting: 1. Before bolting the transducer in place, be sure that it is generally aligned with the tension force (load direction). The transducer is properly aligned when the load direction (bisector of the wrap angle) is pointing along a line connecting the “+” and “-“signs located on the sides of the load cell 2. Insert and finger-tighten the bolts.
ULTRA SERIES SLIM CELL TRANSDUCER 3.4 AO-70263 REV AA MOUNTING THE ROLL Be sure to exercise care during this portion of the installation, as it easy to produce excessive force on the transducer sensing beams. To mount the roll, use the following steps: 1. Loosely fit the roll into the transducer to verify that the shaft and the adapter fit without excessive interference or clearance. For reference, the bore diameter of the hub is +0.0007 and +0.0017 in. (+0.018 and +0.

ULTRA SERIES SLIM CELL TRANSDUCER AO-70263 REV AA 4 TROUBLE SHOOTING Safety should not be an afterthought. Before installing, servicing or calibrating review and follow applicable policies and procedures to ensure worker safety. Machinery must be in a safe state and be aware of any additional hazards that can arise when installing and calibrating higher force transducers.
ULTRA SERIES SLIM CELL TRANSDUCER AO-70263 REV AA 4.1.1 DC RESISTANCE CHECK If you have attempted to resolve your issue using the table above and have been unsuccessful, use the following checks to determine the viability of the transducer. The following nominal DC resistances table indicates a normal load cell, with no load applied at room temperature. The resistances are cited using both the wire color and the M12 connector pin numbers (Figure 7).
