Load Cell Reliability A customer asked us about the stability specifications of our load cells. The initial reaction was that no one does that because there are too many variables. Load cell reliability will depend on the complete system and use. These include using different adapters, different cables, changing thread engagement, overloading load cell, the […]
Load Cell Error- Load Cell Adapter Thread Depth Comparison Budget Versus Shear Web Load Cell Adapter Thread Depth Comparison - Introduction We have written previous articles about using shear web load cells with a threaded adapter installed, meaning they are locked into place. One article described the increased performance by locking a […]
Guarded rejection: 1 Valuable Tool for Reducing the Risk of False Rejection When assessing the conformity of a product or service to a specified requirement, it is crucial to have a high degree of confidence in the decision. This is especially true when the consequences of a false rejection or false acceptance are high. Guarded […]
A Simplified Global and Specific Risk Example A company has hired us to measure the speed of cars on a stretch of a single-lane road. The customer wants options using both Global and Specific Risk examples as they are unsure what method will give them what they need to meet the specification as they know […]
Understanding Global Risk in Simple Terms In the world of engineering and product design, there's a concept that Henry Petroski discusses in his book, "To Engineer is Human: The Role of Failure in Successful Design." He suggests that engineers and companies might become complacent when things are going well. They might not take the necessary […]
The Top 5 Benefits of Automating Force Calibration In the ever-evolving world of technology, automation has emerged as a game-changer, revolutionizing various sectors, including metrology. Imagine setting up a load cell, crane scale, or any force-measuring instrument and being able to pay more attention to the setup and not having to control the machine. Imagine, […]
Delving into Specific Risk: A Comprehensive Understanding of PFA and PFR Specific risk in metrology, mainly focusing on the Probability of False Acceptance (PFA) and Probability of False Rejection (PFR). These concepts are crucial in the decision-making process based on measurement results. Specific Risk Specific risk, as the term suggests, is a risk that is […]
A Simplification of the Differences Between Specific and Global Risk Understanding the Differences Between Specific and Global Risk is a complex topic. For this article, we are going to explain the difference between specific and global risk without getting into too much detail. In metrology, risk is a crucial factor influencing the decision-making process based […]
Decision Rules - Our Top 10 Recommended Reading Many people struggle with decision rules and implementing decision rules. At Morehouse, we have been privileged to be part of the Metrology Handbook 3rd Edition, where we helped write a chapter on decision rules. Though it was an honor to write that and other chapters, there are […]
Treatment of Zero in Determining Deflections – ASTM Method B Interpolated Zero Reduction Methods In calibration, many disciplines take multiple calibration points between the initial zero and the ending zero. What is the standard method for reducing the zero readings from the raw data recorded? When we started asking some contacts at National Metrology Institutes […]
My Load Cell Calibration Does Not Match What the Certificate Says Being in the business of calibrating force and torque instruments means you will run across scenarios where the equipment sent in for calibration performs differently than the last calibration. You might also run into a situation where the end-user does some checks on their […]
5 Essential Facts About Torque Calibration Torque Calibration is essential because almost any fastener has a specification for torque. The purpose is to maintain a clamping force where the fastener stays together and is as immune as possible to fatigue. This article will discuss the five essential must-know facts about torque calibration. We will cover […]
