Voltage Excitation Applied to a Load Cell: Introduction Most load cells are force sensors that receive a voltage (excitation) from a regulated power source (usually a digital indicator or signal conditioner) and send back a low voltage signal (signal) when force is applied. Most load cells are designed to operate at 10V, and many will […]
Decision Rules and Star Wars Henry Zumbrun, President of Morehouse Instrument Company, explores the complex world of decision rules in metrology with an unconventional twist. His article, "The Force of Decision Rules: Applying Specific and Global Risk to Star Wars," featured in the January issue of Quality Magazine, uses the Star Wars saga to shed light […]

This field is about precision, accuracy, and the relentless pursuit of perfection. Despite its […]
6 Things Everyone Should Know About NIST Traceable Force Measurements Many organizations with people in them still use outdated terminology. Such terminology uses the term NIST traceable force measurements or requests that calibration be NIST traceable. In measurement standards, the term "traceability" often invokes thoughts of the National Institute of Standards and Technology (NIST), […]
Comparing Morehouse 4215 Load Cell Meters A common question at Morehouse we are frequently asked involving our 4215-meter load cell meter is if there is a performance difference between the standard 4215 load cell meter and the 4215 Plus. Previously, we decided to make a video to show the upgraded stability of our 4215 HS […]
Comparing Load Cell Meter Filter Settings on Morehouse 4215 Load Cell Meters A common question at Morehouse we are frequently asked involving our 4215-meter load cell meter is if there is a performance difference between using different filter settings. We decided to take things further for this article by testing a standard 4215 indicator versus […]
Converting mV/V Load Cell Signals to Engineering Units: Understanding Load Cell Sensitivity and Signal Conversion. Load cells, integral in measuring force, operate based on strain gauge technology. These devices provide millivolts per volt (mV/V) output, proportional to the excitation voltage. This mV/V sensitivity is crucial, as it determines the load cell's response to force. When […]
Force Measurement and Load Cell Precision Can Drive Auto Innovation In automotive design and engineering, precision isn't just a buzzword—it's the foundation that ensures safety, performance, and reliability. At the core of this precision are force measurement and load cells, the dynamic duo that keeps the automotive industry racing ahead. These crucial tools not only […]
How to Develop an Uncertainty Budget for a Morehouse Calibrated Machine Uncertainty budgets are an essential part of any measurement. They help ensure calibrations are metrologically traceable, accurate, and reliable. Uncertainty budgets are also important for meeting regulatory requirements and accreditation. This article provides insight into developing an uncertainty budget for a Morehouse-calibrated machine. We […]
How to Calibrate Cable Tensiometers Does the Type of Cable GAC versus SSAC Make a Difference? What is a Cable Tensiometer? Cable tensiometers are devices used to measure the tension or force in cables, wires, and ropes. They are commonly employed in engineering, construction, and industrial applications to ensure the proper tension of cables to […]
Lower Limit Factor Improve Calibration Accuracy for Load Cells and Other Force Measurement Equipment LLF, or Lower Limit Factor, is a statistical estimate of the error in forces computed from the calibration equation of a force-measuring instrument when the instrument is calibrated following ASTM E74 standard practice for calibration and verification for force-measuring instruments. The […]
Choosing a Calibration Provider In calibration, decisions often involve finding the perfect balance between competing factors. When purchasing calibration products or services, a classic problem arises: quality, lead time, and price—choose any two, but you can't have all three. As one of the greatest singing artists of our generation sang, "Don't be Sad Because Two […]
