Important Force Measurement Practice - Load Cell with a Flat Base A Load Cell with a Flat Base A Load Cell with a Flat Base can be crucial to obtaining great calibration results with load cells. The error is associated with installing a nonflat base on a multi-column cell. Below is the actual test […]
Torque Explained Formulas and Conversions Torque Explained - In the simplest sense Torque = Force * Length Torque is derived and traceable to SI units of length, mass, and time. The meter is the length of the path traveled by light in a vacuum during a time interval of 1/299 792 458 of a second. The kilogram […]
ASTM E74 Calibration Procedure Simplified - Intro Steps Recommended for Performing Calibration in Accordance with ASTM E74 Stabilization Allow UUT to come to room temperature Warm-up Instrumentation Preparation Select 10-11 Test points IF UUT IS TO BE USED IN BOTH INCREASING AND DECREASING FORCES, THE DEVICE MUST BE CALIBRATED IN BOTH MODES. THE SELECTION OF […]
How to Make Load Cells Perform Better - 3 Benefits of Installing a Threaded Adapter on Load Cells In previous posts, we have been focusing on measurement errors. Good measurement practices such as keeping your force measurement system in control are equally important. We often forget about those practices we put in place to make sure […]
How to Avoid Load Cell Cable Length Errors The majority of force or torque systems we calibrate each year consist of load or torque cells, an indicator or readout, load cell cables, adapters, and some sort of shipping or carrying case. Around 90 % of these systems come in with an indicator only capable of […]
The Measurement Risk Lottery No one won this drawing and the lottery is now up to over $1,300,000,000.00! Measurement Risk Lottery - The Powerball is up to over $1,300,000,000. It is a number so large that it cannot even be displayed on the lottery billboards. How does a jackpot get this high? The odds of […]
Types of Load Cells - Choosing the Right Load Cell for Your Application The purpose of this article is to discuss the common types of load cells used in general force measurements. We will discuss the advantages and disadvantages of each type of load cell. Types of Load Cells consist of the following: Column Load […]
Morehouse 7-Step Process For Troubleshooting A Load Cell Visual Inspection Lets Us Know Which Cell Is Damaged Troubleshooting A Load Cell Simplified. Have you spent countless hours trying to figure out what is not working? Is it the load cell, is it the meter, the cable, or something else? We have wasted countless hours trying […]
Metrological Traceability for Force Metrological Traceability for Force - Metrological Traceability: Property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty. This article will define each level of the measurement hierarchy as it relates to measurement uncertainty for […]
What is Accuracy? Can We Trust the Manufacturer's Specifications? What is Accuracy? Accuracy is influenced by both precision and bias in the measurement process. To understand accuracy, one must understand bias, systematic measurement error, random measurement error, measurement error, and precision. Manufacturers' accuracy specifications may be misleading as they may not tell you how the […]
Tension Links: Are Your Measurements Accurate? You are out in the field with a tension link, load link, or some type of digital dynamometer to use for a weighing application. You need pins to engage into the unit. What can you use? Slings? Maybe one size pin with one diameter on one end and another […]
Calculating Calibration and Measurement Capability (CMC) Using the ASTM Lower Limit Factor (LLF) In accordance with the ASTM E74 standard, Morehouse reports the ASTM Lower Limit Factor (LLF), which is reported on page one of the calibration certificate and is not uncertainty. ASTM E74-06 used to call LLF the uncertainty. The ASTM E74-06 standard was […]
