Torque Transducer Bending Error on Single-ended Arms: CW CCW Torque Test Torque transducer bending error can be one of the most underestimated contributors in single-ended-arm torque calibration. If you calibrate torque transducers on a single-ended arm and you have not characterized the bending error, your uncertainty budget may be significantly off. In our worked example […]
Bad Load Cell Setup: Specific Load Cell Examples, Common Errors, and What to Watch for by Load Cell Type A Bad Load Cell Setup almost never starts with the readout. It starts with the mechanical load path, meaning alignment, adapters, thread engagement, and contact surfaces. When those are not controlled, you introduce off-axis forces such […]
How to Choose Between a Proving Ring and a Load Cell for Force Calibration If you have spent any time in a force calibration lab, you have probably faced this question at least once: Should I use a proving ring or a load cell as my reference standard? It is a topic that frequently comes up when we do […]
Why Your Calibration Lab's Uncertainty Number Is Costing You Money (And Risk You Don't Know About And How to Reduce Calibration Uncertainty) How measurement uncertainty drives false accept and false reject decisions, and why it matters for your quality system. If you've ever had a perfectly good instrument fail calibration, or worse, had a bad one pass, you've experienced the real-world consequences of measurement uncertainty. Most […]
How to Get the Most Out of Your Load Cell with an ASTM E74 Calibration: A Simplified Guide for Novice and Maybe Experienced Users (Yikes). First Things First: What Is a Load Cell? Think of a load cell like a really precise digital scale built into a machine. When you push or pull on […]
What Causes Force Measurement Errors- What Not to Do: Examples of Unsafe or Bad Measurement Practice Expanded explanations and technical basis from Force Calibration for Technicians and Quality Managers (Zumbrun, 2026) This is a selection of examples in our new E-book which explains in much greater detail why each pictured setup represents poor force measurement […]
Dual-Range vs. Dedicated Load Cell Scope. This article summarizes what our calibration certificates show over many years when the same load cell is calibrated in a low range (LO) and a high range (HI). All findings below are derived from the calibration data provided (ASTM LLF history, standard deviation, stability between calibration, and deviations […]
Price, Quality, and Lead Time: Pick Two. At Morehouse We Have Fast ISO 17025 Calibration Services for Load Cells. There’s a saying that goes something like pick and two because there’s no one that can do all three. That makes a lot of sense when you think about it as cheap, fast, and quality is […]
Measurements Gone Wrong: What Real Failures Teach Us About Measurement Risk Most measurement failures don’t start with a dramatic mistake. They start with something ordinary: a unit that isn’t clearly defined, a calibration performed under the wrong conditions, a process step skipped because “it’s always been fine,” or a requirement that no one can clearly […]
