load cell equipment sheet.docx

This is a Load Cell Systems equipment sheet documenting calibration records for testing equipment used in CBM ASTM 74 type calibrations by the State of Illinois. The document provides a comprehensive inventory of load cell systems across multiple capacity ranges, including 1,000 lbf, 20,000 lbf, 50,000 lbf, and 500,000 lbf units, with detailed specifications for compression and tension testing modes. Each load cell entry includes serial numbers, calibration dates (primarily 7/10/2025 and 9/5/2025), recall dates (7/10/2026 through 9/5/2027), loading range specifications, and uncertainty measurements. The equipment is supported by three active digital indicators: Strainsense Conamp 202HR and 20HR models and a Vishay BLH Model LCc-II, with one Strainsense Conamp unit removed from service as of June 1, 2026. The calibration records were initially established on January 28, 2025, and last revised on June 12, 2026.

The document serves as a technical reference for load cell equipment currently in service for calibration work, with most instruments maintained by the Coordinator of Testing within the CBM Calibration program. The procurement associated with these calibrations is designated as a Small Business Set Aside, restricting bidding eligibility to certified small business vendors. The equipment inventory reflects active maintenance and calibration schedules, with most units requiring recalibration within one-year intervals and some extended to two-year cycles based on performance and uncertainty classifications.
