Load cells calibration basics and why is it important? What are the best methods and instruments to use? What industry standards or best practices should I follow? If you are new to force calibration or metrology, the information can be overwhelming. Since force calibration is mechanical in nature, there are many factors to consider. Load […]
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 Load Cell Troubleshooting Have you ever wasted hours troubleshooting a non-working load cell to diagnose the problem? Morehouse technicians have seen many different […]
5 Common Types of Load Cells In the last Back-to-Basics blog, I covered Load Cell Terminology. As I continue to cover basic concepts for beginners, this blog details the common load cell types used in force measurement and how to choose the right load cell type for your application. The four types of load cells […]
Load Cell Terminology In the last Back-to-Basics blog, I covered Measurement Uncertainty. As I continue to cover basic concepts for beginners, this blog details some common load cell terms typically found on a load cell specification sheet. In this post, I will cover Non-Linearity, Non-Repeatability, Hysteresis, and Static Error Band. There are several more terms […]
How to Use a Load Cell Alignment Adapter for Compression Calibration Setups Centering a load cell is critical to obtaining the correct line of force and reducing calibration errors. An alignment plug along with an adapter plate can be used to center a load cell, whether it is a reference standard in a calibrating machine […]
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 […]
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 […]
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 […]
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 […]
Load Cell Stability – How It Can Kill Your Uncertainty Budget Load cells are a combination of metal, strain gauges, adhesive, and more. Like humans, every measuring instrument is subject to aging. Load cells age from mechanical stress or fatigue, and over time this ensures that there will be some instability in the system. Some […]
Multi-axis load cell 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). […]
