2 Facts About How a Force Transducer Measures Force #1 What is a Transducer? In the broad sense of the term, a transducer is a device that turns one type of energy into another type. Some examples are: What is a transducer, battery example A battery is a transducer that converts chemical energy into electrical […]
How to Comply with ILAC P14 when Reporting Expanded Uncertainty ILAC P14 is a mandatory policy document for calibration laboratories accredited to the ISO/IEC 17025 standard. How can a laboratory ensure that expanded uncertainty is reported in compliance with ILAC Policy Measurement Uncertainty in Calibration, ILAC P14? In ILAC P14, section 5 relates to calibration […]
How Do I Calculate B Coefficients Using Data from My Force Calibration Report? At Morehouse, we generate calibration reports with both A and B coefficients. Any calibration performed following the ASTM E74 or ISO 376 standard will list both sets of coefficients. The A coefficients are used to solve for Response when the Force is […]
How to Gain Confidence in Your Measurements In the book Good to Great a concept is illustrated with three intersecting circles, which determine your company’s hedgehog concept. The hedgehog concept is based on asking three questions. “ 1. What are you deeply passionate about? 2. What can you be the best in the world at? […]
How to Participate in an Interlaboratory Comparison (ILC) Many force calibration laboratories need help proving out their measurement capability. The ISO/IEC 17025:2005 listed interlaboratory comparisons (ILCs) in section 5.9.1. However, historically ILCs were not organized or completed because other less complicated methods were acceptable for monitoring the validity of the results. The current ISO/IEC 17025:2017 […]
Why Don’t My Load Cell Force Measurements Match My Calibration Report? You send your load cell out for calibration. When it returns, you begin using the load cell but notice that your measurements don’t agree with what the calibration lab reported. Why is there a discrepancy? This question has been posed to us in slightly […]
3 Ways to Prevent Damage to Your Force Calibration Equipment The purchase of force calibration equipment coupled with the calibration cost can be a large investment. Good, quality equipment provides a steady return on your investment for many years. Unfortunately, we see a lot of equipment damage such as broken connectors, severed cables, damaged load […]
Calibrate your Tuffaloy Weld Force Gauge A weld force gauge accurately measures the actual weld force at the weld. It is important to calibrate these instruments because a weld force that is too low or too high will cause problems such as cracking, indentation, expulsion, and low weld strength. Most spot welding equipment does not […]
Reduce Beginning and Ending Zeros At Morehouse, we generate calibration reports that follow the ASTM E74 standard. When customers try to replicate the data, they often ask how we reduced the zeros from the raw data. This blog explains Method A and Method B zero reduction per ASTM E74. Morehouse recommends Method B, which reduces […]
How to Use a Load Cell Alignment Adapter for Compression Calibration Setups Centering a load cell is critical to obtaining the correct line of force and reducing calibration errors. An alignment plug along with an adapter plate can be used to center a load cell, whether it is a reference standard in a calibrating machine […]
Does a Backup Load Cell Meter for Your Load Cell System Make Sense? Backup Load Cell Meter - Reason Why On Might be Needed A client has four load cells on one meter, and the technician loses, drops, or breaks the current indicator. This is a scenario we see happen quite a bit. If Murphy […]
The Top 3 Things to Consider When Purchasing a Load Cell Usefulness may be the one word we often neglect to consider when purchasing force-measuring equipment or any test equipment. Let's think about that for a bit and let it sink in. Most people I have run across seem to be concerned with price, a […]
