Universal Calibrating Machines Versus Universal Testing Machines - These Machines are Different Morehouse UCM Universal Calibrating Machine - a versatile compression and tension machine used for the calibration of load cells, force gauges, crane scales, and other force measuring instruments for the purpose of calibrating or characterizing the devices for use as secondary standards, working […]
Beware of Load Cell Measurement Error - If a Load Cell is to be Used to Make Descending Measurements, it Must be Calibrated with a Descending Range Note: In the above graph the Blue Line represents the descending curve showing high load cell measurement error when compared to the ascending curve. The difference in output […]
Force Applications for Mass Reference Standards Our good friend, Mark Ruefenacht of Heusser Neweigh, and a Mass Metrology Instructor at NIST pointed out that most mass calibration laboratories will issue certificates of calibration only listing conventional mass (unless True Mass is requested). Force Applications for Mass may create some confusion for those trying to convert […]
What You Need to Know about Having a Load Cell Calibrated with 2 Ranges Load cell calibrated with 2 ranges has a common error that can be referred to as Molecule Excitement Decline might explain why the use of a low range calibration on a reference standard can lead to additional errors. This post will […]
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 […]
Calibration and Measurement Capability (CMC) Force Workbook- ASTM E74 Uncertainty Morehouse has developed a force workbook in Excel to help those trying to figure out measurement uncertainty and how to calculate their Calibration and Measurement Capability (CMC). Updated 10/30/2021! The new update contains coefficients for interpolating uncertainty. Most of this workbook is set up for […]
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 […]
