Pharmaceutical Tablet Forming Machine Optimization
A pharmaceutical tablet producer wanted to monitor the forces applied by the tablet forming machine to understand the relationship between raw material, die set, forming force, and the motor’s cycle speed. The goal was to improve productivity and efficiency of the tablet forming process, while reducing losses such as cracked tablets or voids, by adding a dimension of feedback that could be used to assign specific press adjustment criterion for given inputs. An Interface WMC Sealed Stainless Steel Mini Load Cell (10K lbf Capacity) was mounted in the section of the downward press bar. The machine was modified to accomplish this. The load cell was then connected to a 9320 Portable Load Cell Indicator to collect the needed data. After analyzing the data, the tablet producer was able to quantify adjustment levels by monitoring which forces produced the most optimal results for a given cycle speed, die set, and raw material. Productivity and efficiency were greatly improved by the enhancement of the data feedback.
Tablet Hardness Testing for Pharmaceuticals
A pharmaceutical producer wanted to test and monitor the hardness of the pills being created in their tablet forming machine. Interface’s SML Low Height S-Type Load Cell was mounted to the hardness device inside the tablet forming machine. The SML Low Height S-Type Load Cell was then connected to the 9870 High-Speed High Performance TEDS Ready Indicator to record the force measurements. The tablet producer was able to verify and test the specific hardness needed for their tablets being produced by their tablet forming machine.
Pharmaceutical Tablet Machine Hardness Calibration
A customer wanted to regularly recalibrate tablet hardness testers. The customer needed a miniature load cell the size of a sugar cube that replaces the tablets and fits horizontally in the tablet test-box. Therefore, a special cable exit was important for the compression only calibration application. In the past, the machines had to be rebuilt for calibrations, or a complex mechanism had to be integrated to enable vertical calibration. However, Interface’s MCC Miniature Compression Load Cell measures forces on its side with a special cable exit on the flat side that attaches to the calibration indicator, such as the Interface handheld indicator and datalogger Model 9330. The MCC load-cell calibration set compared the applied forces with the hardness tester to make sure that the tablet hardness tester uses the correct force for future tablet hardness tests. The BlueDAQ software helped to log and compare the data of the MCC reference load cell. The customer successfully verified and calibrated the tablet hardness tester machine horizontally to conduct accurate hardness testing on tablets in the future. Interface’s MCC Miniature Compression Load Cell was perfect due to its small size, and convenient to measure the forces on its side.

Understanding GUM and adherence to good test and measurement practices are essential to minimize uncertainties and ensure reliable measurement results for every application.
In the context of test and measurement, GUM stands for Guide to the Expression of Uncertainty in Measurement. The GUM is a widely recognized and internationally accepted document published by the Joint Committee for Guides in Metrology (JCGM), which provides guidelines for evaluating and expressing uncertainties in measurement results.
GUM establishes general rules for evaluating and expressing uncertainty in measurement that are intended to be applicable to a broad spectrum of measurements. A critical portion of any measurement process, the GUM outlines a thorough framework for uncertainty estimation. GUM defines terms and concepts related to uncertainty, describes methods for uncertainty calculation, and offers guidance for reporting and the documentation of uncertainties in measurement results.
The GUM provides a systematic approach to assess and quantify uncertainties by source, including equipment constraints, environmental conditions, calibration procedures, and human factors. The standards set by GUM emphasizes the need for considering and quantifying all substantial uncertainty components to ensure reliable and traceable measurement results.
By following the principles and guidelines outlined in the GUM, test and measurement professionals, metrologists, and scientists ensure standardized approach to uncertainty evaluation and reporting, facilitating comparability and consistency of measurement results across different laboratories and industries.
The uncertainty requirement varies for different use cases and industry applications. For example, for aerospace, defense, and medical devices there are strict uncertainty requirements compared to commercial scales or measurement tests that do not need precision accuracy.
When estimating uncertainty in load cell calibration, it is important to refer to the Guide to the Expression of Uncertainty in Measurement (GUM). The GUM provides a comprehensive framework with general rules for evaluating and expressing uncertainty in measurement. It serves as a guide applicable to a wide range of measurements, providing valuable guidance on uncertainty assessment in load cell calibration and other measurement processes.
In test labs that utilize load cells and torque transducers, the principles and guidelines GUM should be consistently applied to accurately evaluate and express uncertainties associated with the measurements obtained from these devices.
The application of GUM in test labs using load cells and torque transducers requires a thorough understanding of the measurement process, relevant standards, and calibration procedures. Read Understanding Uncertainty in Load Cell Calibration for more information.
Different considerations to measure uncertainty
- Determine what parameter is to be measured and the units of measure.
- Identify the components of the calibration process and the accompanying sources of error.
- Write an expression for the uncertainty of each source of error.
- Determine the probability distribution for each source of error.
- Calculate a standard uncertainty for each source of error for the range or value of interest.
- Construct an uncertainty budget that lists all the components and their standard uncertainty calculations
- Combine the standard uncertainty calculations and apply a coverage factor to obtain the final expanded uncertainty.
GUM is used to identify and characterize uncertainty sources that can affect the measurements obtained from load cells and torque transducers. These sources may include calibration uncertainties, environmental conditions, electrical noise, stability of the test setup, and other relevant factors. Each of these sources should be quantified and considered in the uncertainty analysis.
Quantitative estimates of uncertainty component contributions to the overall uncertainty need to be determined. This can involve conducting experiments, performing calibration procedures, analyzing historical data, or utilizing manufacturer specifications to obtain uncertainty values for each component.
Once sources and estimates are complete, next step is to combine the individual uncertainty components using appropriate mathematical methods prescribed by the GUM. These methods include root-sum-of-squares (RSS), statistical analysis, and other relevant techniques. The aim is to obtain an overall estimate of uncertainty that accounts for the combined effects of all relevant sources.
The GUM provides guidelines on expressing uncertainties in measurement results. It emphasizes the use of confidence intervals, expanded uncertainty, and coverage factors. The uncertainty should be reported alongside the measurement values, indicating the level of confidence associated with the measurement. This allows the users of the measurement data to understand the reliability and accuracy of the obtained results.
For additional information about GUM, errors and setting an uncertainty budget, watch our webinar Accurate Report on Calibration. The video is set to start on the topic of Measurement Uncertainty.
It is essential to consider the specific uncertainty requirement of the application to ensure that the chosen force measurement device is appropriately calibrated for the project. This resource is a helpful recap: Specifying Accuracy Requirements When Selecting Load Cells.
In addition, understanding GUM, reducing uncertainty with regular calibration of testing devices and proper maintenance of the equipment go together with GUM.
Signal conditioners are used in instrumentation, control systems, and measurement systems where accurate and reliable signal processing is a requirement. The purpose of a signal conditioner is to ensure that the electrical signal from a sensor is compatible with the input requirements of the subsequent signal processing equipment.
Primary features of signal conditioners include amplification, filtering, isolation, and linearization. It can perform various functions depending on the specific application and the type of signals.
Interface Signal Conditioners are used with a wide range of load cell and force measurement devices. Transducers convert force or weight into an electrical signal. The output signal of a load cell is typically in the form of a small electrical voltage that is proportional to the applied force.
Be sure to reference the Instrumentation Selection Guide to find instrumentation with signal conditioners that will best fit your force measurement application.
Understanding Signal Conditioners Use with Load Cells
Amplification: Load cells produce small electrical signals, which may require amplification to bring them to a usable level. Signal conditioners can include built-in amplifiers that increase the magnitude of the load cell signal. This amplification helps to improve the signal-to-noise ratio and enhances the sensitivity of the system.
Filtering: Load cell signals can be affected by electrical noise or interference, which can degrade the accuracy of measurements. Signal conditioners often incorporate filtering capabilities to remove unwanted noise and interference from the load cell signal. This ensures that the signal is clean and reliable.
Excitation: Load cells require an excitation voltage or current to function properly. Signal conditioners provide a stable and regulated excitation source to power the load cell. This excitation voltage is typically supplied to the load cell through the signal conditioner, ensuring consistent and accurate measurements.
Calibration and Linearization: Load cells may exhibit nonlinear characteristics, meaning that the relationship between the applied force and the output voltage is not perfectly linear. Signal conditioners can include calibration and linearization algorithms to compensate for these nonlinearities. By applying appropriate mathematical adjustments, the signal conditioner can provide a linear output that accurately represents the applied force.
Signal Conversion: Load cell signals are typically analog voltages, but they may need to be converted to digital format for further processing or transmission. Some signal conditioners include analog-to-digital converters (ADCs) that convert the analog load cell signal into digital data, enabling it to be processed by digital systems.

Richard Snelson, president of Measurements Incorporated, is the leader of our outstanding manufacturers’ representative firm serving the Mid-Atlantic coast of the US. The origin of the company, that supports customers in this region with application solutions for structural, material, and environmental testing, is an intriguing story.
In this new Faces of Interface feature, Richard highlights one of his favorite projects and provides his thoughts on representing the most reliable and accurate force measurement products in the industry from Interface.
Richard grew up in Philadelphia, Pennsylvania, and was brought up hearing all about his ‘old man’ and the incredible work he got to do with customers across the technology landscape. His father and two partners started Measurements Incorporated in 1976. The company had spun out of another company called Micro Measurements. At that time, they sold a limited range of product lines to a wide range of customers. Some of the most memorable customers Richard would hear about from his dad included those that worked with bridges, battle tanks and even cadavers.
After high school, Richard attended Indiana University of Pennsylvania, where he would go on to earn a split degree in business, marketing, and management. During his college years, Richard also received a ton of career experience working multiple jobs. His summers were spent as a technician in the Princeton Plasma Physics Lab, where his role include working on a reactor. He also worked on the Brooklyn Bridge, replacing cables on the massive structure, as well as working for a friend of his dad in the oil and gas industry. These jobs not only put Richard through college, but they also exposed him to hands-on experience working with organizations and on projects like what his dad would talk about at home when he was growing up.
The experiences and incredible stories he was told throughout his youth pushed Richard to accept a role working for his father’s company. He started out selling one product line, XY plotters, to major test labs and facilities across the Mid-Atlantic. After finding a great deal of success, Richard was given the entire state of Delaware to sell every product line in the company’s portfolio. This eventually expanded into Pennsylvania and Maryland.
As he grew his expertise as a sales rep at Measurements Incorporated, Richard also began buying out the other two owners as they retired and eventually retained sole ownership of the company in 2003. Today the company carries an ever-expanding product line of test and measurement equipment and serves some of the most reputable organizations across multiple industries including, aerospace, defense, medical, industrial, and more.
“I put myself in the customer’s place and offer a complete solution, sometimes reminding them of things they might not initially think of and the end result is that we are all successful.” Richard Snelson, president of Measurements, Incorporated.
Like his father, Richard has also collected many of his own fun, interesting, and sometimes incredibly nerve-racking stories. Among his favorite are the two times he was asked to head over to One World Trade Center to oversee installation equipment and then later assess a challenge with a sensor on the building’s enormous spire on the very top. Richard and few other men from the company charged with some of the tower’s maintenance and caretaking went up to the top together. During the assessment, Richard and the maintenance company’s president were tasked with repelling up the spire to identify and fix the sensor. Richard enjoyed an unforgettable experience and got a sweat-inducing picture in the process that you can see in his photo above!
Richard has a long-time relationship with Interface that began in 2006. He raves about the quality of the brand and the confidence he and his customers have in the accuracy and reliability of our force measurement sensors. He has great respect for the people he works with regularly, including his Regional Sales Director, Elliot Speidell. Richard often finds himself identifying the signature blue paint job on our load sensors during customer facility tours. He’s proud that he’s able to offer the industry’s leading force measurement solutions to some of the world’s most prominent organizations.
When he’s not dangling off one of the tallest buildings in the world or helping solve key customer challenges with a bevy of critical instrumentation, Richard enjoys time spent with family, his wife of 36 years Tracey, their two children Courtney and Derek, and their grandson Everett. The family loves to spend their time outdoors and can often be found sailing on the Chesapeake Bay. Richard also enjoys recreational shooting and cruising around on his motorcycle.
We couldn’t have asked for a better partner in Richard and his team at Measurements Incorporated. We are happy to share his story. Looking for more Faces of Interfaces? Go check out our ForceLeaders here.
Since humans have roamed the earth, there is evidence that science and measurement have played a significant part in the progression of our existence. Early signs of tools and architecture are riddled with measurement references.
History also suggests there was little agreement in any standardization, though there were many proclamations for standard types of units to be used for measurement. One can only imagine how any standardization could take place without our 21st-century technology conveniences used for sharing and collaboration.
Yet, there is a record of the first attempt to standardize measurements by the pharaoh Khufu, in the building of the great Khufu Pyramid around 2,900 B.C. Khufu declared the standard for measurement was to be a fixed unit called the Egyptian Royal Cubit, now recognized as one of the earliest references to any standard of measure.
Scientists have noted that the reason the Great Pyramid is a perfect right angle within 3/1000 of a degree is because of the use of this standard unit of measurement.
With little agreement in standards for nearly 4,500 years thereafter, the use of various weights and measures were littered in the chronicles of designs and renderings by innovators, explorers, astronomers, scientists, and artists that include maps, weapon designs, mechanical inventions, architecture and more.
It is known that Egyptians, Greeks, and Romans were successful in creating standard systems of measurement accepted in their regions; though they didn’t agree with each other’s definitions. As the role of the instrument maker and scientist grew in popularity and prominence, standard weights and measurement tools did too.
At the longing of a Scottish Inventor and Instrument Maker James Watt, a group of scientists was urged to come together to promote a common language in measurement. During the French Revolution, The Royal Academy of Science was instructed to create the new system based on ideas proposed by Watt to promote ‘unity’. Ultimately this is when the meter (Metron) was first set as a standard for measuring distance, and thus the metric system was to be promoted universally for all.
Or would that really be the case? As Europe struggled to accept uniformity, in the independence of the United States, Americans defied the standards and created their own. In the beginning, each state used its own measurement, with little agreement amongst their fellow countrymen. That is until they agreed to a standard called the Parliamentary Yard. This yard was set as a standard by a bar known as Bronze No. 11, which became the US accepted length for a yard and its own standard for measurement. Yet in Europe, the Metric System started to gain traction and greater acceptance.
It wasn’t until 1875, that the International Conference on Weights and Measures got 17 nations to actually agree to a measurement standard under the ‘Treaty of the Meter’ (Convention du Mètre).
It was in 1893 that the United States finally agreed to the standards, using Meter Bar No. 27 and Kilogram No. 20, as fundamental national standards. And to further its commitment to universal standards, in 1901 the US Congress created the National Bureau of Standards, now the National Institute of Standards and Technology (NIST), and authorized it to have custody of standards and manage a catalog of hundreds of standards.
As of 2018, there are 60 Member States and 42 Associate State and Economies of the Meter (Metre) Convention and it remains the basis of all international agreement on units of measurement. The International System of Units (SI) is the modern metric system of measurement. The SI was established in 1960 by the 11th General Conference on Weights and Measures (CGPM), which is the international authority of the SI and modifies the SI.
At Interface, our most frequently referenced SI unit in force measurement is the newton (symbol: N), which is the derived unit of force. It is named in recognition of Isaac Newton’s second law of motion. One newton is the force needed to accelerate one kilogram (symbol: kg) of mass at the rate of one meter per second squared in the direction of the applied force.
Measurement is still evolving, read about the redefined kilogram here.
For reference, the most recent Guide to the SI online is the NIST Special Publication 811, 2008 Edition, by Ambler Thompson and Barry N. Taylor.
Interface has been leading the way in force measurement innovation for the last 50 years, and over the course of our history, we’ve been consistently developing and improving upon our solutions.
A perfect example of this focus on continuous improvements and innovation is seen with our 4 Channel Intelligent Calibration Grade Indicator Model 9840-400-1-T. This solution is ideal for anyone who needs to calibrate a load cell with a single, double or triple bridge. And it just got some impressive new upgrades.
The new version of the 9840-400-1-T Intelligent Indicator features a more modern digital display with additional channels available. It’s now easier to use, with the same high stability and industry-leading performance as the older version of the 9840. Although the quality is the same as our older version, the update can be easily integrated with Interface’s Gold Standard® system and frames, as well as with Microsoft’s Windows® 10.
Interface’s 4 Channel Model 9840-400-1-T allows single loads with three measurements to directly compare outputs to Interface’s Gold Standard load cell, and all measurements can be captured through Interface’s Gold Standard software. This allows users to compare multiple load cells and gather data on whether the load cells are accurate or out of calibration. The 4 Channel Model 9840-400-1-T solution also has the option for high-level input channels.
The Model 9840 is already being used in more than 300 labs, most of which have highly-specific metrology requirements.
‘It is the choice for many aerospace and metrology labs that do in-house calibrations because of its reputation as one of the most accurate calibration tools on the market.” Ken Bishop, Director of Sales Engineering, Interface
Other industries that have expressed great satisfaction with the Model 9840 [user_id], including those in test and measurement and automotive.
