Force Solutions for Medical Tablet Forming Machines

In the medical and healthcare industry, accuracy is an absolute imperative in the devices used in every stage including diagnosis, surgery, health monitoring and even after care. This also applies to the specialized equipment used by pharmaceutical manufacturers, in both design and maintenance, when producing medicine and other healthcare related products.

When it comes to product development in the United States, not only do med devices and pharmaceuticals need to pass rigorous FDA regulations, but they must also be proven to serve patients and doctors safely. This results from robust test and measurement data requirements before seeking clearance. These same types of fundamental safety requirements of testing are also standard in most developed countries when seeking approvals before release.

Medical industry manufacturers turn to Interface because our force measurement solutions are designed for high performance test and measurement, in both accuracy and reliability. There is also a high demand for Interface’s ability to customize solutions to meet the exact requirements of these sensitive applications.

In a variety of medical device applications, one noted example is Interface’s role in providing various miniature beam and in-line load cell solutions with ten times the overload protection to protect against accidental shock loads. Our torque transducers provide rotary and reactive measurement to accurately track light movements required to control prosthetic fatigue testing, surgical equipment, knee or hip replacement and other medical devices. Other Interface solutions include multi-axis sensors for multiple channels of measurement in one housing. Read more about these types of medical applications here.

Interface provides force measurement solutions for a wide variety of products and machines that help biotechnology and pharmaceutical product engineers to design, test and manufacturer devices of all shapes and sizes. When it comes to equipment used in the manufacturing of medicine, Interface products are used to optimize production and reduce waste.

TABLET HARDNESS TESTING

In this application, a pharmaceutical tablet producer wanted to test and monitor the hardness of the tablets 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.

TABLET FORMING MACHINE OPTIMIZATION

For a tablet forming machine optimization project in Europe, a pharmaceutical tablet producer wanted to monitor the forces applied by the tablet forming machine in an effort to understand the relationship between raw material, die set, forming force, and motor 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 Model WMC Sealed Stainless Steel Mini Load Cell 10K lbf 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 Model 9320 Portable Load Cell Indicator to collect the needed data.

TABLET MACHINE HARDNESS CALIBRATION

Our partners in Germany also had the opportunity to work on a calibration project for a device that tested the hardness of tablets, such as a medicine in tablet form. The reason for this type of device is because medical tablets are overly sensitive to compression force when being formed and when ready to be shipped. If the tablets hardness isn’t tested properly, consistency in size and shape is nearly impossible. The need for force testing is because the device must provide very minimal and accurate forces to the tablet for product consistency. When this is applied to tablets that are used in medicine, accuracy in dosage is fundamental and an absolute necessity.

The customer required a unique solution to properly re-calibrate the device. They needed a mini-load cell the size of a sugar cube that replaces the tablets and fits horizontally in the tablet test-box. A special cable exit was also critical for the compression only calibration application.

Interface provided an MCC Miniature Compression Load Cell which can measure forces on its side with a special cable exit on the flat side that attaches to a calibration indicator, such as the Interface battery powered handheld indicator and datalogger Model 9330. The MCC load cell calibration set compares 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 included in our indicator helps to log and compare the data of the MCC reference load cell.

In the past, the customer’s medical tablet machines had to be rebuilt for calibrations, or a complex mechanism had to be integrated to enable vertical calibration. With Interface’s new solution, 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 convenience in measuring the forces on its side.

Interface Load Cell Indicators

At Interface, our claim to fame is that we offer the most accurate and reliable force measurement devices on the market, from load cells to torque transducers and everything in-between. However, no test is complete without the system used to gather the data to evaluate performance results. That’s why we provide a wide variety of instrumentation solutions that include signal conditionersoutput moduleshigh speed data loggersportable load cell indicators, and weight indicators to complete any testing system.

Among the Interface instrumentation products, the most frequently purchased with a force measurement devices are our load cell indicators in various models including handheld, digital, wireless, multichannel, programmable, output modules, analog and bidirectional.

What is a load cell Indicator?

A load cell indicator is a high-accuracy device connected to the output of a load cell to amplify and display the value of the measured load force and weight. Load cell indicators are often needed where the force, load, or weight measurement needs to be visually displayed for the user and displaying the results on a PC is not feasible or desired in the testing environment. For example, testing in the field or confined spaces can make it impossible to connect directly to a PC. In these situations, indicators are used to quickly review and capture force data in real-time.

A few key benefits of load cell indicators include that they provide stable excitation voltage and converts force measurement sensor signals to a digital display. Commonly available features include analog or digital output, selectable digital filtering, peak and valley monitoring and set-point outputs. Additionally, each load cell indicator can be used to connect to four (or more) digital load cells and can display individual readings or the sum of all connected load cells.

Need a load cell indicator?

Interface offers a wide variety of load cell indicators in multiple configurations. Interface indicators come in single to multi-channel weight transmitters and can be found in handheld and portable designs. Things to consider when selecting an indicator are internal sample rate and update rate of the output. A few of our most popular indicators include:

9890 Strain Gage, Load Cell, & mV/V Indicator

Model 9890 is a powerful multipurpose digital load cell meter ideal for weight and force measurement applications. With a max current of 350 mA at 10 V, it can support up to 12 load cells making it perfect for multipoint weight measurement purposes.

Load Cell Indicator Application Note

The application note below provides an example of the benefit of a load cell indicator in real-world use within the medical industry.

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 motor-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 criteria for given inputs.

An Interface Model 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 Model 9320 Portable Load Cell Indicator to collect the needed data.

The indicator was selected as the data collection device because a laptop could have interfered with the test cycle due to space restrictions. The output of the load cell was connected to the 9320 Portable Load Cell Indicator and set aside so that the cable did not interfere with the cycle and no snagging would occur. A cable tie was used to stow aside the cable and to ensure there was enough clearance for the entire cycle.

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.

Force Measurement Solutions for Mobility Markets

One of the tenets in addressing urban mobility is innovation.  As populations grow around the world, addressing how people get from here to there is part of a challenge and opportunity.  Investments are growing in this sector, as experts and designers look to how to increase efficiency and performance in vehicle markets.

Interface has long been a supplier of test and measurement solutions to industries that play a critical role in mobility, from vehicle manufacturers to infrastructure planners and builders. In our latest case study, we look at some of the innovative ways our solutions are being used to advance technologies and capabilities in transportation.

If something moves, it likely needs force and torque testing for reliability, safety and performance. With the evolving trends in urban mobility, Interface is working with makers and builders of all types of transportation solutions for unmanned vehicles like drones and autonomous vehicles, as well as alternatively fueled and electric vehicles.

READ OUR NEW CASE STUDY: INTERFACE’S CRUCIAL ROLE IN VEHICLE AND URBAN MOBILITY MARKETS

Interface customers utilize our standard and custom products in the vehicle and mobility markets to:

  1. Test the force and torque of components for validation or for design improvements
  2. Integration of sensor technology into a component or product for functional real-time performance data

These products include Interface load cells, mini load cells and subminiature load button load cells, rotary and reaction torque transducers, instrumentation, and accessories. For the growing trends for digital requirements in testing and OEM solutions, our wireless and Bluetooth solutions are commonly used in these markets.  Interface is also frequently engaged on specific customer requests for engineer-to-order products and customized solutions.

Here are four use case scenarios of Interface solutions used in the vehicle and mobility markets:

Brake Pedal Testing

Interface’s Brake Pedal Load Cell BPL-300-C was installed on a brake pedal and then connected to a BTS-AM-1 Bluetooth Low Energy Strain Bridge Transmitter Module, which collects and transmits data to our BTS Toolkit Mobile App. This solution allowed the customer to record and review data from a mobile device while out on a test track. READ MORE HERE.

Drone Delivery Systems

Interface supplied four WMC Sealed Stainless Miniature Load Cells to measure the payload weight and  for the detection of in-motion shifting and uneven distribution of the package weight. As the load cells detect this data, it provides a signal to the propeller to increase RPMs on the propellers and adjust balance and weight distribution inflight. WATCH HERE.

Electric Vehicle (EV) Battery Testing

Compression testing performed on EV batteries is critical for performance and safety. As an EV battery is charged and stores more electrons, it swells. If the packaging housing the batteries does not compensate for this swelling in the design, failure is likely. Interface can supply a WMC miniature load cell. The load cell will measure compression force as a battery goes through charge cycles on a test stand to determine the force given off as the battery swells. This allows our customers to design the proper packaging for the batteries. Read more about the future of EV markets and testing here.

Engine Performance Testing

Force and torque sensors are used with a dynamometer, which isolates the engine’s power output to help quantify its overall performance.  In this application, a  precision SSMF Fatigue Rated S-Type Load Cell is attached to a torque arm to “feels” the torque from an engine loading system. The fatigue rating on the load cell allows it to accurately measure performance for extended cycles. A signal conditioner is used to connect out from the load cell to a computer to ensure clear transmission of data to accurately measure torque being produced by the engine. Engineers analyze power transfer through the data output to tune the engine performance. Check out this engine dynamometer application note here.

Contact our experts to learn more about these types of testing applications, use cases and products used in urban mobility projects.

Testing for Commercial Drones and Parcel Delivery

Drone parcel delivery, and the use of drones in general, has expanded rapidly throughout the world. A technology that was once relegated to science fiction and imagination is becoming a real-world asset and making a huge impact on many commercial use applications in military and defense, consumer goods, logistics and inventory management, industrial automation, construction, security, agriculture, healthcare, imaging and surveying, as well as shipping and fulfillment.

To give you an idea of the impact of drones, take a look at recent numbers published by the FAA on registered drones in the U.S.:

  • 1,710,159 Drones Registered
  • 495,909 Commercial Drones Registered
  • 1,210,751 Recreational Drones Registered
  • 195,346 Remote Pilots Certified

There is a significant role for test and measurement as well as embedded sensors in this growing industry, which is expected to reach of $6B in size in the next few years. Load cells play a huge part in the design and development of this specialized aircraft technology and ongoing monitoring while in flight. Drones are classified as unmanned aerial vehicles. Basically, an aircraft without a human pilot. Successful operation of a UAV is dependent on a system, including the vehicle, a ground-based controller, and communications components, all of which must pass rigorous performance testing standards and constant data feedback.

The knowledge and tools we apply to test and measure airplanes and spacecraft performance can be transferred at a smaller scale to drones. Drone OEMs need to collect data points on thrust and velocity in test, and they also need to collect real-time sensor data on drones in-use. In fact, a large variety of sensor types are used for drone applications, including: force sensors, gyroscopes, barometers, and accelerometers.

Most recreational drones have passed significant testing during the engineering and design phase to ensure safety for anyone on the ground. Early applications and adoption sparked immediate regulation and safety requirements. We are now seeing the fastest expansion of this technology into commercial use. The future of drone technology for wide-scale business use has several of the world’s largest companies engaged in expansive development and deployment in use of UAVs for package delivery, including Alphabet (Google), Amazon, UPS, CVS and Walmart.

Commercial applications require substantially more rigorous testing in all use cases, in particular for transportation of objects. Most developed countries have defined commercial use requirements and regulations, such as the FAA in the U.S. Not only is the safety of those on the ground important critical, so is protecting the value of the goods in transport.

In demonstrating how force measurement solutions are used with drone technology, Interface created animated application note showcasing how a force solution is necessary for real-time monitoring of drones used in the shipping and fulfillment markets. Testing beyond flight, there is a level of complexity present when you introduce the weight of a package to a drone.

DRONE TESTING USE CASE

Customer Challenge:

A customer approached Interface to deliver a force solution capable of weighing a “payload” and using that data in real-time to tell the propeller motors to compensate for weight shifting or uneven weight distribution. The purpose of the force solution was to help the drone lift the payload and fly normally to reach its destination.

Interface Force Measurement Solution:

To solve this challenge, Interface supplied four WMC Sealed Stainless Steel Miniature Load Cells, which were used to measure the weight of the payload and detect weight shifting and distribution in flight. As shifting and uneven distribution occurred, the load cells send a signal to the necessary propeller motors to compensate.

How it Works:

The four miniature load cells are connected independently to each of the four landing gear legs. The load cells are then connected to the drone’s processor, which allows the load cell to communicate the weight of the payload and store the information. As the drone flies and weight shifts, the load cell can then relay the information to the processor in real-time so that the individual motors increase in RPM to balance the shifting weight.

This new series of animated application notes give viewers a better sense of how force measurement products are applied to real-world challenges to collect and analyze data. So far, we have produced three animated application notes, which we have linked below:

 

Driving Force in Automotive Applications

Among the most highly regulated industries in the world, automotive is up there with the likes of medical and defense. Every component and system needs to be thoroughly tested and deliberately analyzed to ensure that the final product is safe for the driver, other vehicles and pedestrians. Any mistakes or failures can cause catastrophic damage and put lives at risk.

There are hundreds of thousands of different tests that car parts and software go through before they are approved for the road. Among them is force measurement testing. Force and torque tests are integral to the structural and mechanical design and build of the car. Gathering data on the build quality and safety of materials and components found within cars, trucks and more is done through a wide variety of different force measurement testing.

Interface has been a partner to the automotive industry for more than 50 years, from the major OEMs to smaller parts manufacturers and test labs. We build force and torque sensors and acquisition devices designed to provide automotive engineers and manufacturers with high-quality data to monitor and confirm the design and in-action processes of a wide variety of vehicles.

Force testing applications for the automotive industry involve everything from structural, engine, brake, seat belt and suspension tests, all the way down to individual lug nut torque testing.

Recently, Interface has also been supplying solutions to those in the growing electrical vehicle (EV) market. EV cars and other motor vehicles present a wide variety of unique challenges for engine torque and battery technology testing.

As an example of some of the products we offer to the industry, we are highlighting Interface expertise in different automotive applications. This will include specific examples of work we’ve done for our customers recently or in the past.

BRAKE PEDAL TESTING

One of the largest areas of automotive test and measurement we are involved in is brake pedal testing. Our customers need to ensure that applying certain amounts of force to the brake will slow and stop the vehicle as intended.

In this application note, Interface supplied our customer with a BPL-300-C Brake Pedal Load Cell, which was installed on the brake pedal. As the user depressed the brake pedal, force data was transmitted by our BTS-AM-1 Bluetooth Low Energy (BLE) Strain Bridge Transmitter Module to the BTS Toolkit Mobile App and displayed on a mobile device. This allowed our customer to view and graph the data in real-time.

Read the application note for Brake Pedal Testing here.

EV BATTERY TESTING

In the EV market, one of the most integral pieces of technology is the battery used to run every piece of hardware and software in the car. One of the critical tests that’s performed on EV batteries in compression testing. As an EV battery is charged and stores more electrons, it swells. If the packaging that houses the batteries is not intelligently designed to compensate for this swelling, you could have a major problem.

For this challenge, Interface can supply the popular WMC Miniature Load Cell. The load cell will measure compression force as a battery goes through charge cycles on a test stand to determine the force given off as the battery swells. This allows our customers to design the proper packaging for the batteries.

Read more about Interface’s role in the The Future of Automotive is Electric.

SUSPENSION TESTING

A personal favorite of the Interface team is a suspension test we performed on a race car. As you can imagine, race car components need to be finely tuned for optimal performance. The suspension is one of the most significant factors in the tuning process.

Using an Interface Model 1200 Standard Load Cell, we were able to measure simulated motions of a racetrack including bumps, banks and other track conditions. This allowed the customer to gather highly accurate (0.04%) measurements of loads applied to individual suspension points. This type of suspension testing technology can also be performed on a regular commercial automobile, but the race car example is much more fun!

View the race car suspension testing application here.

MOTOR TESTING

In this motor test stand application, it was used in the quality control lab of a major automotive manufacturing customer that needed to test, record and audit the torque produced by a new motor design under start load.

Interface supplied a Model AxialTQ Rotary Torque Transducer that connected between the motor and the differential, on the drive shaft, which could measure and record these torque values. Based on the data collected using the AxialTQ, AxialTQ Output Module, and customer laptop, the test engineer was able to make recommendations to optimize the amount of torque created by the new motor design.

You can read more about the AxialTQ in this post.  

The wide variety of applications for automotive force testing that Interface has been involved in is significant. We have many published application notes beyond those highlighted, including Seat Testing, Engine Head Bolt Tightening and one for an Engine Dynamometer (dyno for short) use case. The examples listed above just scratch the surface.

Interface Mini Load Cells Growing in Product Use and Testing

One of the biggest manufacturing trends over the past decade is the miniaturization of hardware components. Reducing the size and weight of products and the components, while increasing the power of complex technology systems, is growing in use across all industry segments using force measurement in design and production.

The growing trend to utilize sensor technology in miniaturized products has been especially significant in the medical, consumer products, technology and robotics industries. These industries are looking to fit more force and measurement capabilities into a package that is the same size, or in many cases, considerably smaller than previous generations of like products.

To address this expanding trend, Interface Mini™ Load Cells were designed specifically for light touch, light weight, high accuracy, and robust performance to utilize for OEM products and smaller testing applications in confined spaces. Our miniature load cells provide exceedingly accurate measurements, similar to our full-size load cells and utilize our proprietary alloy strain gages. Capacities are available as low as 0.11 lbf / 0.5 N and as high as 100 kN.

These small-scale load cells are engineered and manufactured to provide extremely accurate output data with the same degree of precision performance as our standard load cells. OEM’s must have this sort of precision force technology because many of the devices being made today are minuscule and more complex in comparison to earlier products and testing application use cases.

In the medical device industry, innovative and often small new products are used in various life-saving applications. Any inaccuracy or miscalculation of force can have devastating effects. Take a look at how our Interface LBS Miniature Compression Load Button Load Cell and 9330 High Speed Data Logging Indicator were used to record the force measurements when designing and testing vascular clamp surgical devices. You can also read about the Vascular Clamp application note here.

In our earlier Mini Load Cells 101 blog, we discussed the features and benefits of Mini Load Cells in detail. Today, we are highlighting some of our best-selling and new Mini Load Cell solutions available from Interface.

Applications for Consumer Products and Packaging

When we think about force measurement and its relation to product development, we often consider the aerospace, automotive or industrial industry. However, many of Interface’s customers use load cells and torque transducers to test and develop machinery used for consumer products and in the packaging industry.

In order to meet this demand, customers need force measurement tools that are both accurate and provide the necessary data points to automate and regulate consumer packaging machinery. This consumer packaging case study takes a look at the wide variety of applications of force measurement tools used to create consistency and quality among the products consumer buy and use daily.

BACKGROUND

If you have ever wondered how a pill or piece of candy gets a little logo stamped on it without crushing it or how every bag of chips is nearly filled to the same capacity, chances are a load cell or torque transducer was involved. Interface works with hundreds of customers who manufacture a wide variety of machines used in the consumer packaging industry. These machines serve numerous functions including logo stamping, bag weighing, bottle capping, sealing, and precision cutting.

According to Grandview Research, the use of automation, as well as robotics throughout the packaging lines, has seen tremendous growth in recent years. The aim is to improve productivity, reduce the operating costs and prevent waste, thus improving the overall efficiency of the packaging systems. “Big Data” has also gained popularity with operation managers that collect machine data to regulate the performance of the machinery, undertake preventive maintenance and maximize the up-time.

CHALLENGE

The challenge our customers run into when building these machines is they require a high level of precision to get consistent and repeatable results. If the machines are incorrectly calibrated, it can lead to excessive waste. For instance, if a bottle of soda isn’t capped correctly, it can leak, or if the machine which embosses toilet paper and napkins is too forceful, the paper will be ripped to shreds. Currently, most packaging machines are relying on physical hard stops, clutches, monitoring motor current and laborious tasks to monitor and apply the necessary force and torque. To ensure proper performance and to reduce waste, the most accurate and reliable force measurement tools are required.

SOLUTION

Interface works with hundreds of original equipment manufacturers (OEMs) who develop machines for the consumer packaging industry. Depending on the function of the machine, we manufacture a wide variety of force measurement products to help reduce waste, ensure repeatable results and provide accurate data to help consumer packaging customers automate their processes.

All of our products come with various data communication systems, including analog or digital and Bluetooth®, wireless or Ethernet. This provides customers with flexibility in their data collection methods and the ability to connect systems through the Internet of Things (IoT) functionality. For machines using a precision twisting motion, such as capping machines, we offer nearly 50 types of reaction torque transducers and rotary torque transducers for customers. All of our torque transducers are precision-machined and use our proprietary torque sensors for the most accurate data possible.

For precision weighing or stamping, such as the candy stamping application, we manufacture more than 60 different types of load cells and Interface Mini Load Cells. These load cells have capacities as low as 1 lbf (500 gf) for extreme precision. In our customer’s application highlighting candy stamping, a test apparatus was outfitted with the Interface Model WMC Mini Load Cell and a 9330 Data Logging Indicator to measure the compression force required to imprint the candy without crushing it and collect data to finely tune the process.

For applications using robotics, Interface offers multi-axis sensors to test force and torque measurements simultaneously in three mutually perpendicular axes.

RESULTS

Accuracy in packaging is a game-changer for cost-savings, production efficiency, time-to-market, and product safety. Whether you are measuring, weighing or securing, Interface load cells, mini load cells, torque transducers, and instrumentation can assure you the quality and accuracy you need to protect your brand and customer satisfaction.

Interface is one of the leading force measurement manufacturers for the consumer packaging industries. We work directly with OEM’s and engineering consultants to implement systems and products which help to reduce waste, automate the packaging process and provide accurate, repeatable results.
