load cell equipment sheet.docx

This is a Load Cell Systems equipment sheet documenting calibration records for the State of Illinois' Concrete and Bituminous Materials (CBM) testing program in support of a rebid solicitation for ASTM 74 type calibrations. The document maintains a comprehensive inventory of load cell equipment across multiple capacity ranges—from 1,000 lbf to 500,000 lbf—detailing specifications for both compression and tension testing modes. The equipment list includes 12 active load cells and one unit removed from service as of June 1, 2026, with associated digital indicators from manufacturers including Strainsense and Vishay BLH. Calibration dates are documented with recall dates ranging from July 10, 2026 through July 10, 2027, and the original document was revised on June 12, 2026, reflecting current maintenance and certification status.

The load cells are classified by capacity with documented loading ranges, uncertainty measurements (ranging from 0.017 to 29 in Class A), and NIST identification numbers for traceability. Each unit includes serial numbers, calibration modes, and specific uncertainty values critical for testing compliance. The equipment supports the state's materials testing program and is maintained through a structured calibration schedule managed by the Coordinator of Testing within the CBM Calibration division, with records maintained in the Testing department's documentation system.
