How to Calibrate Tension Links and Load Shackles: It is all About the Pin When it Comes to Tension Link Calibration A tension link is calibrated on its pins, not on its label. Two links stamped with nominally the same capacity can behave completely differently under load because they were built around different pins, and […]
What a Recovering Drug Addict Taught me about Saying No: When Metrology Companies Should Say No I went to a Vistage seminar for the inspiration on learning a better way to say “no”. By Henry Zumbrun, CEO, Morehouse Instrument Company Michael Brody-Waite stood in front of a room full of CEOs at my Vistage […]
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 […]
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 […]
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 […]
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 […]
