Specifying a Tolerance, the Difference Between Percentage of Indicated Value vs % of Full-Scale Output.

June 09, 2020 12:00:00

I assume almost everyone has seen an accuracy specification. This article questions those specifications as several manufacturers do not let you know what criteria they used to set the specification. This can result in severe under-reporting of measurement uncertainty and lead to catastrophic failures. hashtag#better hashtag#force hashtag#measurement starts with educating our customers on what matters and how to make better measurements

Does a Backup Meter for Your Load Cell System Make Sense?

May 22, 2020 12:00:00

We've had numerous people ask us if it makes sense to have a backup meter? This article provides guidance on extra calibration fees and what is needed to substitute a meter. As always, the answer is going to be about your risk tolerance.

Evaluating the "Usefulness" of force calibration equipment.

March 04, 2020 12:00:00

Out of the three main concerns; price, physical size, and manufacturer's specification, none of these give the full picture of if the device is useful or not. I think many of us want our expectations met when we buy something; however, that does not always happen. This article discusses these and other concerns one must account for if they want a force-measuring system

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.

January 27, 2020 12:00:00

Why read this article? If you use load cells, the chances are that someone is setting them up using a 2 point or 5 point span calibrations. This type of setup often has high errors. This article discusses a more accurate way to eliminate the majority of these errors. Morehouse goes on to explain what mV/V is and why using a calibration curve may be the most accurate method for displaying the results in engineering units such as lbf, kgf, N.

How to Calculate the Resolution of a Load Cell

October 24, 2019 12:00:00

Curious as to how to calculate the resolution of the force-measuring device submitted for calibration, or how the laboratory calibrating your device is calculating a value for resolution. Are they calculating it correctly? This post describes the importance of resolution and how to calculate it.

The Importance of Considering Reproducibility in the Measurement Process Uncertainty

October 07, 2019 12:00:00

Reproducibility is often confusing, and many find the topic difficult. However, capturing values for repeatability and reproducibility of a measurement process for determining a lab's calibration and measurement capability does not have to be hard. This post offers simplified solutions as well as several references as to what reproducibility is.

Morehouse Has an App to Convert Force to Mass, Mass to Force and it uses NOAA so it should be known to within 5 ppm!

August 27, 2019 12:00:00

A body of known mass can have different weights (force applied by gravity) based on its location on earth. This simple concept has been a significant source of error in mass measurement, particularly when the measurement device is calibrated to force at a different location. The good news is that with the right information, this error can be corrected mathematically. Morehouse’s Local Gravity App helps you do this correction based on the GPS data from your cell phone.

How to Calibrate S-Beam or S-Type Load Cells

July 17, 2019 12:00:00

S-beam or S-Type load cells were designed for several weighing applications and may not be suitable for several force applications. Any misalignment in the load path will produce significant measurement errors. This blog discusses the error sources and how one can try and correct them.

Aircraft and Truck Scale Calibration Tips

June 18, 2019 12:00:00

This blog details three things needed to properly calibrate aircraft scales. The 3 things are as follows: the right equipment, the right adapters, and the right process. Using a machine that has bending or is not level will produce large errors, not simulating the tire of the airplane or truck can produce large errors, and not properly converting force to mass or mass to force can all lead to incorrect results and errors of well over 2 % on a scale with a tolerance of 0.1 %.
