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 […]
Load Cell Transitioning from One Mode to Another. Does it Make a Difference? This post will examine the effects of Load Cell Transitioning by calibrating the load cell in compression by switching to tension and then back to compression versus calibrating in tension first and then compression. We will determine if there is a statistical […]
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 […]
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 […]
