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 […]
In the last Back-to-Basics blog, I covered Calibration versus Verification. As I continue to cover basic concepts for beginners, this blog will define measurement uncertainty and examine why it is important. What is Measurement Uncertainty? What measurement uncertainty is not is an error. It is imperative to understand the difference between these two terms as […]
In the last Back-to-Basics blog, I covered Compression and Tension Force Calibration. As I continue to cover basic concepts for beginners, this blog will cover the differences between calibration and verification. What is a Calibration? Let me start by stating that there are several definitions of calibration across multiple standards. My favorite definitions are below. […]
Compression and Tension Forces Calibration In the last Back-to-Basics blog, I covered How a Transducer Measures Force. As I continue to cover basic concepts for beginners, this blog will cover the terms Compression and Tension Forces and how they relate to force calibration. Compression and Tension Forces: What is a Compression Force Calibration? When discussing […]
How a Transducer Measures Force In our first Back-to-Basics blog, I covered Force Calibration and its Importance. As I continue to cover basic concepts for beginners, this blog will define a transducer and describe how one is used to measure compression and tension force. What is a Transducer? In the broad sense of the term, […]
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 […]
Guide for Understanding Uncertainties on a Morehouse ASTM E74 Calibration Certificate Reporting the Expanded Uncertainty on an ASTM E74 Calibration Certificate of the measurement is a requirement of ISO/IEC 17025 and likely always will be. However, if you look at several different certificates of calibration, their Expanded Uncertainty reported, contributors and reporting methods will vary […]
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 […]
