Top 5 Specifications to Consider for Load Cell Accuracy

One of the most important considerations when purchasing a load cell is its accuracy. However, a load cell datasheet typically does not contain all the specifications needed to determine an accuracy statement. Which specification on a typical datasheet is most important? Do all specifications impact accuracy? Does it matter how the specification is expressed? The […]

Force Calibration Accuracy

At Morehouse we are frequently asked about Accuracy, with a question such as “What is the accuracy of this system you offer for sale?” At first glance it should be an easy question to answer and, indeed, we could simply give a glib answer of “our system is accurate to 0.005 % of full scale.” […]

Load Cell Troubleshooting

In the last Back-to-Basics blog, I covered Types of Load Cells. As I continue to cover basic concepts for beginners, this blog details how to troubleshoot a load cell. 7 Step Process for Troubleshooting a Load Cell Have you ever wasted hours troubleshooting a non-working load cell to diagnose the problem? Morehouse technicians have seen […]

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

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 can strike, chances are it will eventually occur. We have had numerous clients ask us about how to backup or how to substitute a meter […]

Evaluating the "Usefulness" of force calibration equipment

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 manufacturer's specification sheet, and maybe the physical size of the force-measuring […]

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

Understanding what mV/V is and how does it relate to load cells 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 is the ratio of the output voltage to the excitation voltage required […]

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

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 in a scale, used as a lifting system, or process weighing for […]

Calibrating Multi-Axis Load cells in a Morehouse Calibrating Machine

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 blog […]

How to Calibrate Button Load Cells and Achieve Good Results

How to Calibrate Button Load Cells and Achieve Good Results Anyone that has tried to calibrate button type load cells knows they do not repeat well in rotation.  The sensitivity to off-axis or side loading conditions is quite high.  High enough that 0.1 % of misalignment is going to produce a rather large cosine error.   […]
