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 has mainly specified tolerances as a percent of full scale. Several crane scales, tension links, and hand-held force gauges follow this […]
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 […]
About Morehouse This article is intended to give a brief history of Morehouse Instrument Company and Information about Morehouse beyond force and torque measurement. Morehouse has been in business since March 15, 1920. The company started as a local machine shop. Mr. Morehouse owned the company, and Harry E Zumbrun worked with him. When Mr. […]
How to Calculate the Resolution of a Load Cell Per Section 4.14 of JCGM 200:2012, Resolution is the “smallest change in a quantity being measured that causes a perceptible change in the corresponding indication.” Over the years, this simple definition has become a topic of confusion in the metrology community. We are hoping to simplify […]
The Importance of Considering Reproducibility in the Measurement Process Uncertainty - Intro Most people in the metrology community will agree that a calibration laboratory's ability to reproduce measurement results belongs in an uncertainty budget. Several Accreditation Bodies require reproducibility to be at least considered as part of a calibration laboratory's Calibration and Measurement Capability (CMC). […]
Morehouse Has an App to Convert Force to Mass, Mass to Force and it uses NOAA so it should be known to be within 5 ppm! When someone asks us about converting force to mass, Morehouse can now say we have an app for that. Not only will our app convert force to mass, but […]
How to Calibrate S-Beam or S-Type Load Cells and Achieve Good Results Figure 1 General S-Beam Load Cell General Overview of S-beam or S-Type load cells S-beam or S-Type load cells were designed for several weighing applications. Most were designed to be mounted on a scale, used as a lifting system, or process weighing for […]
Important Aircraft and Truck Scale Calibration Tips - Intro Figure 1: Example of Aircraft Weighing Aircraft and Truck scales come in all different shapes and sizes and typically serve one purpose, to approximate the weight of an aircraft or truck. Why might that be important? For Aircraft, it's about knowing the center of gravity CG. […]
