CLEVELAND-KIDDER® SLIM CELL TRANSDUCER INSTRUCTION MANUAL . . .
1.0 GENERAL INFORMATION 1.1 RECEIVING AND UNPACKING Handle and unpack the equipment carefully. Immediately upon arrival, check the shipment against the packing list. Any damage should be reported immediately to the carrier and to the nearest CMC representative. Equipment that will not be installed immediately should be stored in a clean, dry location. Precautions should be taken to prevent moisture, dust and dirt from accumulating in storage and installation areas 1.2 PRECAUTIONS 1.2.
1.4 DESCRIPTION The Cleveland-Kidder SLIM CELL transducers utilize a sensing twin beam to which semiconductor strain gages are bonded. With these high output signal gages a very small force on the sensing beam will be shown as a change in the tension signal. For many applications SLIM CELL transducers are for use with rotating (live) shaft rolls that are traditionally mounted in Pillow Block Bearings. See Figure 1. For mounting dimensions see Figure 2.
2.0 INSTALLATION 2.1 location for the transducers where the wrap angle does not vary. The change in indicated tension that will result can be calculated and, if small, may not be significant. SELECTION OF TRANSDUCER MOUNTING LOCATION 2.2 When selecting a transducer mounting location, keep in mind that the tension-sensing roll must NOT be mounted where the web wrap angle can vary.
2.4 INSTALLATION OF THE TRANSDUCER application. The Slim Cell can be mounted directly to the machine frame or to the optional mounting bracket. Drill and tap two mounting holes in the machine frame for each bracket. Refer to dimension X in Figure 2 for the proper bolt diameter. The Slim Cell is mounted to the bracket with 3 bolts. Before mounting the load cell in place read the instructions below (Orientation and Mounting of the Slim Cell) to insure that it is properly aligned.
output signal of the transducer is positive. If the force points to the “-“ the output is negative. This is importance to know when wiring the transducer to the amplifier, indicator, or controller terminals. Interchanging the B (black wire) and C (red wire) connections may be required in order to provide the proper signal polarity for the device. (see Figure 6). 2.6 INSTALLATION PRECAUTIONS To insure proper installation and operation of the system, the following steps should be performed in sequence.
4.0 TEMPERATURE COMPENSATION The transducers are supplied with a temperature compensation network (except size 1 that don’t require it) which is in series with the output signal lead. The compensation circuit is designed to be used with a tension amplifier, which has an input impedance of 10K Ohms when a pair of transducers connected as a full bridge is used. If only one transducer is used, the tension amplifier impedance should be 5K Ohms.
