ULTRA SERIES UNDER PILLOW BLOCK TRANSDUCER MAN-70254REV. AA 1.4.3 CRITICAL ROLL SPEED Even with a balanced roll, a vibration can be set up in a stationary shaft. If this vibration (in cycles per minute) occurs at the harmonic frequency of the shaft, the transducers can be damaged. To determine critical roll speed, use the following formula: Critical roll speed in RPM = 4.8 x 106 x Shaft O.D.

AA 2.1 FORCE RATINGS Refer to Table A in this document for Transducer Maximum Working Force Ratings. 2.2 BEFORE INSTALLING THE TRANSDUCER Before installing the Transducer, perform the following steps: 1. Review the Installation Precautions (Section 2.2.1 on page 9). 2. Review the Safety Considerations (Section 2.2.2 on page 9) 3. Review the Mounting Configurations (Section 2.2.3 on page 10) 4.
ULTRA SERIES UNDER PILLOW BLOCK TRANSDUCER 2.2.3 MAN-70254 REV. AA MOUNTING CONFIGURATIONS Ultra Series Under Pillow Block Transducers are designed for use with shafts that are mounted in Pillow Block Bearings. See Figure 1.
ULTRA SERIES UNDER PILLOW BLOCK TRANSDUCER MAN-70254REV. AA 2.2.4 MOUNTING HARDWARE AND FASTENER TORQUE RECOMMENDATIONS The Table B provides you with guidelines to refer to when determining torque values for clean and dry fasteners. Keep in mind, however, that several variables can influence the “optimum” torque to be used in a given situation, and Table B should be used only as a general reference.

ULTRA SERIES UNDER PILLOW BLOCK TRANSDUCER MAN-70254REV. AA 3 INSTALLING THE UNDER PILLOW BLOCK TRANSDUCER The following sections provide you with detailed information and steps to correctly install the Ultra Series Under Pillow Block Transducer. 3.1 ORIENTING THE UNDER PILLOW BLOCK TRANSDUCER The Under Pillow Block transducer must be oriented so that the resultant tension force direction (bisector of the wrap angle) is in the same quadrant as the load direction arrow on the side of the UPB.

AA Figure 5 – Mounting the Under Pillow Block Transducer 3.4 MOUNTING THE PILLOW BLOCK BEARING TO THE LOAD CELL Note: The UPB is normally shipped with a pillow block mounting plate but is occasionally ordered without one if the customer chooses to make their own. Mounting the pillow block bearing to the UPB is simple and convenient. The mounting plate is held in place by four stainless steel corner bolts.
MAN-70254REV. AA 3.6 ULTRA SERIES UNDER PILLOW BLOCK TRANSDUCER SHAFT EXPANSION If the roller is subjected to higher temperatures after installation, thermal shaft expansion may damage the transducers. To prevent damage to the transducers, an expansion type pillow block bearing should be used. 3.7 MOUNTING THE SENSING ROLL The following steps take into consideration the risk and difficulty of handling large rolls and help to minimize the number of failed attempts at mounting the roll. 1.

MAN-70254REV. AA ULTRA SERIES UNDER PILLOW BLOCK TRANSDUCER 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 UNDER PILLOW BLOCK TRANSDUCER 4.1 MAN-70254 REV. AA 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 ).
