Understanding Risk: Making Better Measurement Decisions Understanding Risk Intro: Why Measurements Aren’t Always Exact Every measurement we take comes with some level of doubt. This doubt is called measurement uncertainty. It’s the range within which the “true value” probably lies. When understanding risk, think of it like reading a ruler: if your eyes […]
Start With the End in Mind: Working Backwards to Size Your Measurement Equipment and Calibration Provider A practical, risk-informed method for selecting equipment, decision rules, and calibration providers Abstract Begin with the decision you must defend—product conformance with acceptable risk—and work backwards to derive the measurement capability required of both your equipment and your […]
Which Force Machine Should I Choose? Anyone in metrology has asked—or been asked—this question at some point: “What’s the right force machine for my application?” How do you decide? Word of mouth? A manufacturer’s reputation? Measurement uncertainty? Overall quality? Price? Or some combination of them all? It’s a lot like buying a car. […]
Proving Rings vs. Load Cells — Definitions, Accuracy, and a Practical Comparison. After teaching many classes for NCSLI, ASQ, and other force measurement programs, one question always seems to come up: Which is better—Proving Rings vs. Load Cells? Instead of giving a one-sided answer, the following section takes a closer look at both options. The […]
Morehouse Custom Load Cell Design: 10 Steps Encompassing Comprehensive Principles, Innovative Process, and Best Practice Designing a reliable custom load cell starts long before metal is cut or gauges are bonded. It begins with a clear understanding of what is being measured, where the sensor will live, and how its signal will be used. This […]
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 […]
