100 Years of Morehouse and 100 Blog Posts The 100th blog post, what to do? 100 years in business, 100 blog posts, several papers, and technical articles along the way. Communication has changed from a switchboard phone to a handheld personal computer that can receive this message. From the proving ring to today's deadweight […]
What Calibration Coefficients Do ASTM E74, ISO 376, and other standards may use calibration coefficients to characterize the performance characteristics of continuous reading force-measuring equipment better. These standards may use higher-order fits such as a second or third-order fit (ISO 376) or ASTM E74 allows higher-order fits up to as high as a 5th-order. Both […]
Load Cell Calibration: What Does “Traceable to NIST” Really Mean? Load cells have various applications across several fields, from verifying the correct amount of stamping press force to testing rocket thrust stands. They are so common that almost everyone owns several in some shape or form, whether they realize it or not. Load cells are […]
ASTM E74 and Accuracy Statements: Why an Accuracy Statement Does Not Belong on Every Calibration Certificate - Intro The current ASTM E74-18 standard is the title Standard Practice for Calibration and Verification for Force-Measuring Instruments. Here at Morehouse, we support the best practices that are outlined in the ASTM E74 standard as the representation […]
Does a Backup Load Cell Meter for Your Load Cell System Make Sense? Backup Load Cell Meter - Reason Why On Might be Needed A client has four load cells on one meter, and the technician loses, drops, or breaks the current indicator. This is a scenario we see happen quite a bit. If Murphy […]
The Top 3 Things to Consider When Purchasing a Load Cell Usefulness may be the one word we often neglect to consider when purchasing force-measuring equipment or any test equipment. Let's think about that for a bit and let it sink in. Most people I have run across seem to be concerned with price, a […]
Specifying a Tolerance, the Difference Between Percentage of Indicated Value vs % of Full-Scale Output - Intro In looking at various equipment, it seems the force equipment in the test and measurement industry specifically specifies tolerances as a percent of full scale. When determining accuracy or tolerance, several crane scales, tension links, and hand-held force […]
Converting an mV/V Load Cell Signal into Engineering Units: Why This May be the Most Accurate and Cost-Effective Way to Use a Calibration Curve Most bridge-based sensors typically specify a rated output Sensitivity (R.O.) shown in Figure 1 below. This Rated Output is generally found under Electrical specifications. It is usually in mV/V, where mV/V […]
