Multi-axis load cell Multi-Axis load cells are becoming more popular, and the calibration of such load cells creates various challenges to ensure minimal cross-talk and to calibrate each axis of the load cells. This blog describes a detailed test plan for calibrating a 3-axis multi-axis load cell in a Morehouse. Universal Calibrating Machine (pictured below). […]
The Top 5 Costly Force Measurement Mistakes #1 of 5 Costly force measurement mistakes Most calibration laboratories will say a device is "In Tolerance" without considering the uncertainty of their measurement process. This equates to you not using a calibration laboratory that has standards to meet your needs and accounts for measurement risk properly. Most […]
Why the Location of the Measurement is More Important than You May Realize Calling an instrument “In Tolerance” is about the location, location, and location of the measurement. It’s also about the uncertainty of the measurement, but a bad location will raise the Probability of False Accept (PFA) significantly. The Probability of False Accept is […]
Recommendations for Specifying ASTM E74 Calibration Services Recommendations for Specifying ASTM E74 Calibration Services. This document is intended to help properly specify what you may need for ISO/IEC 17025 accredited ASTM E74 calibrations to ensure you are getting exactly what you need: Verification of the Calibration Supplier Can meet the Requirement. Reviewing many accredited laboratory […]
Calibration Intervals - When is it Time to Recalibrate? Calibration Intervals A calibration interval is the period between two consecutive calibrations of MT&E. This interval is crucial for ensuring that the equipment continues to operate within its specified performance and the claimed Calibration and Measurement Capability (CMC) uncertainty parameter, sometimes referred to as […]
The 3 Important Changes to ISO 9001 Compliance and What This Means for Force and Torque Instrumentation The 3 Key Changes to ISO 9001 Compliance and What this Means for Force and Torque Instrumentation are discussed in detail in this article. What you need to know about documented procedures, preventative actions, and top management. Change […]
Avoid ASTM E74 Load Cell Calibration Mistakes We are writing this post to clarify some common ASTM E74 misconceptions and discuss ASTM E74 Load Cell Calibration Mistakes. We have written two early blogs on the ASTM E74 standard: ASTM E74 Simplified and Calculating CMC using the ASTM E74 standard. We also have a slide share presentation detailing the […]
Force Applications for Mass Reference Standards Our good friend, Mark Ruefenacht of Heusser Neweigh, and a Mass Metrology Instructor at NIST pointed out that most mass calibration laboratories will issue certificates of calibration only listing conventional mass (unless True Mass is requested). Force Applications for Mass may create some confusion for those trying to convert […]
ASTM E74 Calibration Procedure Simplified - Intro Steps Recommended for Performing Calibration in Accordance with ASTM E74 Stabilization Allow UUT to come to room temperature Warm-up Instrumentation Preparation Select 10-11 Test points IF UUT IS TO BE USED IN BOTH INCREASING AND DECREASING FORCES, THE DEVICE MUST BE CALIBRATED IN BOTH MODES. THE SELECTION OF […]
How to Make Load Cells Perform Better - 3 Benefits of Installing a Threaded Adapter on Load Cells In previous posts, we have been focusing on measurement errors. Good measurement practices such as keeping your force measurement system in control are equally important. We often forget about those practices we put in place to make sure […]
Calibration and Measurement Capability (CMC) Force Workbook- ASTM E74 Uncertainty Morehouse has developed a force workbook in Excel to help those trying to figure out measurement uncertainty and how to calculate their Calibration and Measurement Capability (CMC). Updated 10/30/2021! The new update contains coefficients for interpolating uncertainty. Most of this workbook is set up for […]
Morehouse 7-Step Process For Troubleshooting A Load Cell Visual Inspection Lets Us Know Which Cell Is Damaged Troubleshooting A Load Cell Simplified. Have you spent countless hours trying to figure out what is not working? Is it the load cell, is it the meter, the cable, or something else? We have wasted countless hours trying […]
