How Low Can My Load Cell Go? Load Cell Impact on Measurement Uncertainty
There are enough load cell intricacies impacting measurement uncertainties to write a book strictly on that subject, which Morehouse Instrument Company President Henry Zumbrun has already done.
His newest article, How Low Can My Load Cell Go? appears in Cal Lab Magazine. He notes that management often wants to spend the least on equipment and push equipment such as load cells to their lowest operational level. Using equipment such as load cells below 5 – 10 % of their capacity or lower, such as 2 %, is a frequent practice that demands attention as it can significantly impact measurement uncertainty as a percentage of applied force.
The article examines the impact on measurement uncertainty of using a load cell as low as 2 % of its rated capacity, compliance with ISO 376 and ASTM E74 lowest force point criteria, and how to uphold the reliability necessary to maintain a specific calibration interval. What holds for these standards can apply to any load cell.
Zumbrun writes that the question “How low can my load cell go?” involves intricate considerations to maintain a low measurement uncertainty and maintain the reliability one needs to maintain a specific calibration
interval.
The assessment of measurement uncertainty, including factors such as resolution, reference standard stability, ASTM LLF or other specifications, when applicable, and the uncertainty of the calibration standard, is vital for understanding the limitations and precision of a load cell at lower force levels.
Moreover, adherence to industry standards, such as ASTM E74 and ISO 376, provides clear guidelines and recommendations on the minimum force points for load cell usage.
Cal Lab Magazine is the international journal of metrology. Cal Lab Magazine is a quarterly publication that covers measurement science and instrument calibration for managers, engineers, and technicians. Since 1994, Cal Lab Magazine has continued to cover international standards, calibration techniques, and new technology for measurement areas: electrical, dimensional, temperature, pressure, flow, and mass.
