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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
