Force Calibration Simplified: Expected Performance in Load Cell Calibration Procedures Expected performance in load cell calibration procedures is a key concept that we have adopted at Morehouse. The term likely originated from discussions during ASTM committee meetings among industry experts. Expected performance helps define how accurately a force-measuring tool works when tested under ideal laboratory […]
Embracing Failure in Calibration: Why Failing Fast, Failing Often, and Failing Cheap Is the Key to Growth (Embracing Failure as a Leader and a Metrologist) Many of us have been conditioned to fear failure. From early school years to professional life, success is often celebrated, while mistakes are typically hidden or punished. Yet what if […]
Deadweight Force Machine Stability: Long-Term Reliability in Force Calibration Morehouse has a new paper on Deadweight Force Machine Stability titled "Deadweight Primary Standards: Best Practices and Their Associated Risks for Stability Determination in Compliance with ISO/IEC 17025" Overview Deadweight force machines are considered the pinnacle of force calibration standards, delivering the lowest possible measurement uncertainties […]
High Capacity Force Calibration Above 4.4 MN (1,000,000 lbf) Figure 1 Picture of Morehouse High Capacity Force Calibration 10MN System UCM Using Three Symmetrical Morehouse Load Cells In previous posts, we have discussed ASTM E74 requirements for secondary standards. However, we have not discussed what happens when primary standards cannot calibrate the secondary standards. Such […]
What is Hysteresis? Almost any load cell specification sheet has a term called Hysteresis. This particular article hopes to explain what the term load cell hysteresis is. Load Cell Accuracy: Simple Definition In a simplistic sense, hysteresis is a way to measure how well a load cell returns to its starting point when force is […]
Load Cell Specifications Explained Figure 1 Example of a Typical Morehouse Load Cell Specifications Sheet Load cells are precision devices used to measure force or weight, and their performance is defined by various specifications. The purpose of this article is to explain the typical load cell specifications sheet. Let's break down the key parameters […]
Understanding Load Cell Resistance and Its Impact on Performance: A Comparison Between 350 OHM and 2800 OHM Load Cells At Morehouse, we have been asked about the differences between load cell input and output resistances, which typically range from 350 OHM to 2800 OHM. This blog aims to provide a deeper understanding of load cell […]
Expressing SI Units on a Keyboard: Rules and Keyboard Shortcuts Anyone who has ever written an article, manuscript, website copy, copy for their calibration certificates, or any writing involving proper SI usage has likely had some confusion on how to make sure what they are writing is technically correct. We see it all of […]
Accuracy and Precision in Force Measurement Simplified When taking measurements, two critical concepts to understand are Accuracy and Precision. While related, Accuracy and Precision describe different aspects of measurement quality. Accuracy refers to how close a measurement is to the true value. A measurement is considered accurate if it is close to the actual or […]
