TUR and Picking the Right Load Cell Distributor (UPC vs. PC vs. Calibration Cells) The Question That Keeps Coming Up A customer recently asked: “The quote earlier was for Ultra-Precision load cells. Do we need to go for that grade to calibrate devices known to within 0.1 %, or is there an alternate model that […]
Deadweight vs. Hydraulic Force Calibration: Understanding the Difference Selecting between Deadweight vs Hydraulic Force Calibration is one of the most critical decisions in any force calibration laboratory. The choice directly impacts measurement uncertainty, productivity, and compliance with international standards such as ISO 376 and ASTM E74. This document explains how each method realizes force, the […]
Understanding the Normal Distribution The normal distribution, sometimes called the bell curve or Gaussian distribution, is one of the most important concepts in statistics. It describes how values of a variable are spread, and it often appears in nature, science, and everyday life. What is the Normal Distribution? At its core, the normal distribution […]
The Role of the En Ratio in Force Calibration Confidence In the world of calibration, proving that your measurements are both accurate and defensible goes beyond simply watching control charts. While control charts are powerful for spotting drift or unusual trends, they don’t answer a critical question: are our stated measurement capabilities truly valid? To […]
Start With the End in Mind: Working Backwards to Size Your Measurement Equipment and Calibration Provider A practical, risk-informed method for selecting equipment, decision rules, and calibration providers Abstract Begin with the decision you must defend—product conformance with acceptable risk—and work backwards to derive the measurement capability required of both your equipment and your […]
Which Force Machine Should I Choose? Anyone in metrology has asked—or been asked—this question at some point: “What’s the right force machine for my application?” How do you decide? Word of mouth? A manufacturer’s reputation? Measurement uncertainty? Overall quality? Price? Or some combination of them all? It’s a lot like buying a car. […]
Force, Mass, and Weight: What is the Difference? Force, mass, and weight are related concepts in physics, yet they are distinct and often misunderstood. Introduction to Difference Between Force, Mass, and Weight Figure 1. NBS Document Regarding Force Calibration Services I recently read an old NBS unpublished Provisional Document of "The Force Calibration Service" […]
What is Non Linearity? Almost any load cell specification sheet has a term called static Non-Linearity. This particular article hopes to explain what the term Non Linearity is. Load Cell Accuracy: Simple Definition of Non Linearity In simplistic terms Non Lineratiry tells us how much a load cell's readings might not follow a straight line […]
What is Static Error Band (SEB)? Almost any load cell specification sheet has a term called static Error Band. The term itself can be used to describe one of many accuracy specifications found on a load cell specification sheet. This particular article hopes to explain what the term Static Error Band is. Load Cell Accuracy: […]
Stain Gauge or Strain Gage? There is a debate on how “strain Gauge” should be spelled. Should it be “Strain Gauge or Strain Gage.” The purpose of this post is to provide a little bit of research history on the advent of the strain gauge or strain gage. Through some research, it seems the proper […]
Tensile Force: Understanding the Pulling Power in Materials Tensile force is a fundamental concept in materials science and engineering that refers to the force exerted when an object is pulled or stretched. This pulling force causes tension within a material, leading to elongation along the axis of the applied force. Understanding this force is crucial […]
Strain Gauge: How a Load Cell Measures Force Strain Gauge is sometimes misspelled as a strain gage. A strain gauge is a sensor used to measure strain (deformation) on an object. Here's a brief overview of strain gauges: Structure: Typically, it consists of a thin, flexible, insulating backing that supports a metallic foil pattern. The […]
