Description

The requirement is for thirty-one (31) each load cells size one ton; fifteen (15) each load cells size ten ton; twenty-six (26) each load cells size thirty ton with data; with Option FY02 for 0 _ 22 each size and Option FY03 for 0 _ 10 of each size with data. The load cells shall conform to the requirements as specified in Purchase Description MLLE-AIB-00-01 dated 15 May 2000. This purchase description describes load cells and accessories consisting of the following items: 2,000 LBF Compression-Tension Load Cell with 10 ft. cable, upper adapters, lower adapters and carrying case; 20,000 LBF Compression Load Cell with 10 ft. cable, upper adapter, lower adapter and carrying case; 60,000 LBF Compression Load Cell with 10 ft. cable, upper adapter, lower adapter and carrying case. Performance Requirements: The following characteristics are minimum requirements unless otherwise indicated. Function: The load cells will be used as secondary force standards in the Air Precision Measurement Equipment Laboratories (PMELs). Commercial Items: Commercial versions of the load cells shall have been sold in the commercial market place in significant quantities. Modifications may be made to the commercial load cells to meet the calibration requirements, and 7-wire special cable and connector. Environmental Requirements: The load cells shall meet all performance requirements when operated in ambient temperature 0 to 40 degrees Celsius, and atmosphere of 10% to 50% relative humidity. Nominal Load Capacity: The load cells shall have the following nominal loads: 1 each 2,000 lbf tension and compression; 1 each 20,000 lbf compression; 1 each 60,000 lbf compression. Nominal Sensitivity: (Nominal output signal at full scale) 2mV/V. Temperature Coefficient of the Zero Point OER 10 Degrees C: <+/-0.013%. Repeatability: <+/-0.01% nominal load. Combined Error: <+/-0.017% of full scale, (0.34 lbf for 2,000 lbf load cell, 3.4 lbf for 20,000 lbf load cell, 10.2 lbf for 60,000 lbf load cell). The load cells will be checked in the AFMETCAL Force Laboratory on the 100,000 lbf and 2,000 lbf Deadweight Calibrators. The accuracy of the weights is better than 0.003% of applied load. The load cells will be calibrated in accordance with ASTM E74, _Standard Practice of Calibrating Force Measuring Instruments for Verifying the Force Indication of Testing Machines._ The uncertainty, as described in ASTM E74, Section 8.4, shall not exceed the error limit, +/-0.017% of full scale. Hystersis: <+/-0.017% full scale. Creep: (At full scale and 23 degree C), Over 30 minutes: <+/-0.017% of full scale; Over 24 hours: <+/-0.05% of full scale. Limit Load: (Overload with no change in calibration): 150% of nominal load. Breaking Load: (Overload with no mechanical damage): 300% of nominal load. Cable: The cable shall be 7-wire shielded cable, 9 to 11 feet long. Cable Connector: A 1-MS3106PEMV 7-pin connector shall be supplied at the end of cable to mate with the HBM Model DMP40 Indicator. Load Cell Adapters: Load cell adapters, as needed, shall be supplied to adapt to Morehouse force calibrating machine, part number C-99728, used in the Air Force PMELs. Over-all length and configuration must be the same as adapters currently manufactured by Morehouse Instrument Company. Carrying Case: A carrying case with a rigid foam insert must be provided for each load cell and its adapters. The bottom adapter will be attached to the load cell. The case will provide a separate cutout for the top adapter and tension rods. Testing: Acceptance will be at destination AFMETCAL. One hundred percent acceptance testing will be performed at destination to assure the items meet the requirements. The contractor shall replace load cells the fail acceptance testing. Acceptance testing will be completed within 45 days of receipt. Evaluation Procedures: If a non-approved item is offered, evaluation and approval by AFMETCAL/MLLE/MLEE is required prior to contract award.
