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 […]
Measurement Risk in Business Decisions: The Likelihood and the Consequences of Measurement Risk I’ve worked on this topic for many years and continue to teach, refine, and learn. This article reflects that ongoing process and is intended to clarify what measurement risk is, how it shows up in practice, and why it matters. Measurement risk […]
How to Calibrate Cable Tensiometers: Addressing Error Sources and Promoting Standardization Figure 1: Henry Zumbrun uses a Morehouse Cable Tensiometer Machine (PCM-2MD-T1). How to Calibrate Cable Tensiometers: Introduction Cable tensiometers are precision instruments used to measure cable tension in aerospace, industrial, and structural applications. Accurate calibration of these devices is essential to ensure reliable force […]
TUR and Picking the Right Load Cell Distributor (UPC vs. PC vs. Calibration Cells) The Question That Keeps Coming Up A customer recently asked: “The quote earlier was for Ultra-Precision load cells. Do we need to go for that grade to calibrate devices known to within 0.1 %, or is there an alternate model that […]
Deadweight vs. Hydraulic Force Calibration: Understanding the Difference Selecting between Deadweight vs Hydraulic Force Calibration is one of the most critical decisions in any force calibration laboratory. The choice directly impacts measurement uncertainty, productivity, and compliance with international standards such as ISO 376 and ASTM E74. This document explains how each method realizes force, the […]
