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 NBS Document Regarding Force Calibration Services I recently read an old NBS unpublished Provisional Document of "The Force Calibration Service" […]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 […]
Understanding Tension Load Cell Equations Tension load cells are critical for measuring pulling forces in various applications. Here at Morehouse, we calibrate many tension load cells from various capacities. One of the more essential aspects of these calibrations is ensuring the appropriate adapters are used. Our e-book and other documents speak to the importance of […]
Introduction of TEDS for Load Cells Transducer Electronics Datasheet, or TEDS for load cells, is something we are frequently asked about as, over the years, the topic has been of interest to many hoping to use a load cell with a chip in it and be able to hook it up to multiple meters, to […]
Load Cell Shunt Calibration Load Cell Bridge with a Shunt Calibration. Load cell shunt calibration is a cost-effective means to confirm that the load cell and indicator system are not experiencing significant drift or potential damage. Load cell shunt calibration involves introducing a known electrical resistance (shunt resistor) in parallel with the load cell, allowing […]
ASTM E74 Change From Previous to Meet a Two-year Calibration Interval ASTM E74 Change From Previous to meet a two-year calibration interval is found in the ASTM E74 standard in section 11.2.1. The standard specifically states, “Force-measuring instruments shall demonstrate changes in the calibration values over the range of use during the recalibration interval of […]
