Morehouse Force Calibration Adapters for Calibration of Lifting Devices such as Crane Scales, Tension Links, and Dynamometers Figure 1 Morehouse Tension Force Calibration Adapters Quick Change Tension Member System I am about to tell you a little bit about our calibration adapter history and what we have been working on to simplify your life when […]
Choosing the Right Load Cell Indicator Does the indicator have to be better than 0.005 %? Are you willing to use a computer to convert mV/V to Engineering Units? Do you require portability without a power adapter? Do you have more than two load cells? HADI Do you require portability without a power adapter? Do […]
Guidance on Uncertainty Budgets for Force Measuring Devices Part 3. Calculating Uncertainty for Force Measuring Devices for Measurement or Calculating Uncertainty for Force Measuring Devices Background: Currently, there are discrepancies regarding what is acceptable for a force calibration uncertainty budget. A common mistake is to include too many lines from the load cell specification sheet. For […]
Guidance on Uncertainty Budgets for Force Measuring Devices Part 2. Calculating Uncertainty in Accordance with ASTM E74 Standard Calculating Uncertainty in accordance with ASTM E74 Standard Background: ASTM E74 Standard Practice of Calibration of Force-Measuring Instruments for Verifying the Force Indication of Testing Machines is the standard followed by many in North America for the […]
Guidance on Uncertainty Budgets for Force Measuring Devices Part 1. Why Do We Need a Solid Guidance Document? Uncertainty Budgets for Force Measuring Devices Introduction: All calibration laboratories accredited to ISO/IEC 17025 must submit uncertainty calculations for the Calibration and Measurement Capability uncertainty claims included in the scope of accreditation. The assumptions made to determine the uncertainty […]
What Happens When You Overshoot a Test Point? Various calibration laboratories use hydraulic, screw, and other force calibration machines where it is difficult not to overshoot a test point. By talking about overshooting a test point, we are referring to loading past the desired point and then letting the creep in the hydraulic system naturally […]
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 […]
Presenting a Tutorial at NCSL International Presenting a Tutorial at NCSL Step 1. Write an abstract and state the learning objective. The abstract is the summary of the class. The learning objectives are concise statements about what students will be able to do when they complete instruction. T17 — Fundamentals of Torque Calibration – […]
How to Calibrate Button Load Cells and Achieve Solid Results How to Calibrate Button Load Cells - Intro Anyone that has tried to calibrate button-type load cells knows they do not repeat well in the rotation. The sensitivity to off-axis or side-loading conditions is quite high. High enough that 0.1 % of misalignment is going […]
