Small in Dimension and Precise in Measurement

The world of force measurement is vast. Interface products are used across industries and in a wide range of applications. From the measurement of minute forces in catheter stint testing to jumbo load cells for massive structural testing of rockets, Interface load cells provide highly accurate measurement no matter the size of the load cell.

One of the many benefits of Interface products is the extensive range of measurement capacities and dimensions we offer, including our Mini Load Cells used for small and precise measurements. Interface Mini™ load cells are ideal for light touch, weight, or limited space test and measurement applications. The Mini Load Cells provide remarkably accurate measurements like our LowProfile load cells. With capacities available as low as 0.11 lbf / 0.5 N and as high as 100 kN, there are various miniature load cells for testing and options for custom OEM solutions.

TIP: Explore your options with our Mini Load Cell Selection Guide

Typical applications for measuring tiny, accurate forces are within the medical, manufacturing, robotics, and consumer product industries.

Medical device manufacturers are working to provide handheld point-of-care devices for patients. Additionally, medical devices used within the human body must provide extremely delicate forces to achieve their intended purpose without harming the patient.

Take something that seems relatively simple, like a vascular clamp. These types of delicate instruments are used on heart valves. If they provide too little force, they cannot do their job. However, providing too much force could severely harm the patient. Medical device manufacturers of these surgical tools use miniature load cells to measure the clamping force to ensure precise accuracy to toe the line between too much and too little force, which is a very precise number.

In the pharmaceutical industry, very small load cells are crucial for accurately measuring the force applied to the pills (tablets) during the press marking phase and other manufacturing processes to ensure consistent dosage and tablet integrity.

With consumer products, precision force measurement is critical to various manufacturing processes and real-time monitoring. A load button load cell is the right size for testing the durability of a smart device by applying a force to the screen and measuring the amount of force the screen can withstand before cracking or breaking.

A miniature load cell can measure the force required to open a food package. This information can be used to ensure that the packaging is easy for consumers to open and secure enough to protect the food from damage. In food processing, load cells measure the force applied to food during mixing, blending, and other processes to ensure consistent product quality and prevent damage to the food itself. For instance, load cells can monitor the force applied to a dough mixer to ensure the dough is correctly mixed without becoming overworked or tough.

SMALL AND PRECISE MEASUREMENT APPLICATIONS

SPECIMEN RESEARCH

In the medical industry, medical experts need the best equipment to research multiple specimens. In this case, a medical researcher needs to monitor the load force of their linear actuator that uses a needle to collect material from the desired specimen. Interface’s SuperSC S-Type Miniature Load Cell can easily be installed into the linear test stand. A needle with a gripper on the end is installed on the lower end of the SuperSC. As the needle is pushed to collect specimen material, the load feedback is captured using the 9330 Battery Powered High-Speed Data Logging Indicator through an SD card or another laptop. Read: Specimen Research App Note

AIRBAG CONNECTOR TESTING

Testing airbag connectors functionality is needed to ensure perfect deployment in case of a car crash. Eight to twelve connectors are installed in each vehicle, and tests must be made to clarify whether the connectors are working effectively. These connectors usually work when latched, but that does not ensure the electrical properties are performing. The amount of force needs to be tested to see when an electrical current is connected. Interface’s solution is to attach the WMC Sealed Stainless Steel Miniature Load Cell to the actuator of the test rig. The airbag connector is placed at the test rig’s bottom. Forces are applied and measured using the 9330 High-Speed Data Logger as the connector is pushed down to latch together. When connected to a computer, results can be logged, downloaded, and reviewed.

COBOT MONITORING SYSTEM

Collaborative robots, or cobots, are offering more manufacturing operations in the industrial packaging industry. Protective cages or fences are no longer needed for safety purposes, but safety testing is still required to ensure humans and robots can work together. Four 3-axis Force Load Cells (creating one 6-axis Force Plate) are installed between two metal plates at the base of the cobot. Interface suggests installing a 6-axis force plate under the cobot and two ConvexBT Load Button Load Cells in the pinchers of the cobot. If a human were to knock into the cobot or have any object stuck in the pincher, the cobot would sense the force measured from the load cells and be programmed to stop immediately.

Interface can serve a wide range of test and measurement applications from millions of pounds force to the most minute. If you want sensors with small, more precise measurement capabilities, please check out our miniature load cell selection guide.

Types of Interface Load Cells Used by Pharmaceutical Companies

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.

Like medical devices, pharmaceutical machines and products must undergo a variety of mission-critical tests before they are safe for distribution to uses. Interface products are selected by the pharmaceutical industry is due to our product’s accuracy and reliability, in addition to our deep experience in supplying solutions to those in the medical business.

Accuracy Matters for Weighing and Scales

 

Off-Axis Loading 101

Off-axis loading refers to a situation where a load cell, which is a device designed to measure force or weight, is subject to forces that are not aligned with its primary sensing axis. Load cells are typically designed to measure forces that are applied along a specific direction or axis, which is known as the primary sensing axis. When forces are applied to the load cell in other directions, this is referred to as off-axis loading.

Off-axis loading can affect the accuracy of load cell measurements, as the load cell may not be able to accurately distinguish between forces that are applied along the primary sensing axis and forces that are applied in other directions. This can result in errors in the measured weight or force.

To minimize the effects of off-axis loading, load cells are often designed with measures to reduce sensitivity to forces applied in other directions. These may include mechanical features such as strain relief structures or specialized materials that are more resistant to off-axis loading. Additionally, load cells are often installed and used in ways that minimize the likelihood of off-axis loading, such as aligning the primary sensing axis with the direction of the applied force. Be sure to carefully follow all Force Measurement Installation Guides provided with sensor.

What can be done to protect from off-axis loading?

Off-axis loading can affect the accuracy of load cell measurements, so it is important to take steps to protect against it. Here are a few ways to do so:

  • Use proper mounting and alignment: Load cells should be mounted and aligned in a way that ensures that the primary sensing axis is aligned with the direction of the applied force. This helps to minimize off-axis loading and ensure accurate measurements.
  • Use appropriate accessories: Using accessories such as adapters or mounting bases can help to ensure that load cells are properly aligned and oriented, minimizing the potential for off-axis loading.
  • Use anti-rotation features: Many load cells are equipped with anti-rotation features, such as bolt-hole patterns or keyway slots, which help to prevent the load cell from rotating around its mounting point. This can help to maintain proper alignment and reduce the effects of off-axis loading.
  • Use overload protection: Overload protection features, such as limit switches or stoppers, can be used to prevent load cells from being subjected to excessive forces or moments. This can help to prevent damage to the load cell and ensure accurate measurements.
  • Use a protective enclosure: Load cells can be placed in protective enclosures that shield them from external forces and environmental factors. These enclosures can help to protect against off-axis loading, as well as other types of interference.

By taking these steps, load cell users can help to protect against the effects of off-axis loading and ensure accurate and reliable measurements.

Product designs that mitigate off-axis loading

Engineers are constantly working to design new load cells that are more resistant to off-axis loading.  In fact, Interface product engineers have several products that are designed to protect from off-axis loading, including:

  1. ConvexBT Load Button Load Cell
  2. SuperSC S-Type Miniature Load Cell
  3. MBP Overload Protected Miniature Beam Load Cell
  4. MRTP Miniature Overload Protected Flange Style Reaction Torque Transducer
  5. MBI Overload Protected Miniature Beam Load Cell
  6. LBMP Overload Protected Compression Load Button Load Cell
  7. SMT Overload Protected S-Type Load Cell
  8. WMCP Overload Protected Stainless Steel Miniature Load Cell with Male Threads

By optimizing the mechanical design of load cells to minimize their sensitivity to off-axis loading this can include use of materials, such as composites or alloys, which are more resistant to deformation and strain. It also includes the use of specialized geometries that can help to distribute forces more evenly and reduce the effects of off-axis loading.

As well, engineers utilize built-in electronic compensation to correct for the effects of off-axis loading. This may involve using additional sensors or feedback loops to monitor the load cell’s response to external forces and adjust the output accordingly.

Interface engineers use a multi-disciplinary approach to designing load cells that are more resistant to off-axis loading. By combining advances in mechanical design, electronics, manufacturing, and simulation, they are creating load cells that are the most accurate in by classification in the world.

New Technical White Paper Analyzes SuperSC S-Type Miniature Load Cells

Interface recently introduced a revolutionary new miniature load cell, the SuperSC. The extremely compact design makes it an ideal all-purpose load cell with high accuracy measurement in an exceedingly small form factor.

The SuperSC (SSC) models are part of the Interface product line of shear s-cells. They are specifically designed as environmentally sealed and insensitive to off axis loading. This product is available in capacities ranging from 25 to 1000 lbf (100 N to 5 kN). The new SuperSC force transducer easily fits requirements for a high accuracy sensor that can be designed into components, equipment, and end products.

In our new technical white paper, Eccentric Loading Analysis for SuperSC S-Type Miniature Load Cell, Interface’s Raymunn Machado-Prisbrey, Design Engineer for OEM Solutions, provides an extensive review of the performance and capabilities of the new SuperSC.

The paper details FEA analysis performed on spring elements of equivalent capacity, in this case 250 lbs. Two eccentric load scenarios were considered: a full scale axially applied load with three degrees of misalignment and a full scale load applied to the edge of the element loading surface. Results of this analysis are available in the new white paper, available for download here.

Additionally, the new technical review highlights SuperSC data, misalignment analysis and edge loading, providing results and images of each test.

The Eccentric Loading Analysis for SuperSC S-Type Miniature Load Cell conclusion sums it up clearly. The Interface SuperSC S-Type Load Cell outperforms traditional s-type bending cells in output consistency and safety factor stability when loaded at three degrees of axial misalignment.

The SuperSC has a higher output change under edge loading conditions than the s-type design; however, linearity is much better and safety factor remains acceptable. S-bending cells are not capable of withstanding this level of edge loading from a mechanical standpoint.

You can also watch the recorded online seminar below to get the inside scoop on this revolutionary new product.

Top Selling Interface Ruggedized Products

These types of products follow strict certification standards and ratings. During the online seminar, Interface product experts detail the standards and ratings related to intrinsically safe products, sometimes referred to as hazardous location use, as well as solutions designed to meet safety, regulatory or compliance requirements.

The standard ensures that an intrinsically safe device is incapable of triggering combustion or igniting any gasses or vapors. The device is safe to use around dust and gas without risking static electricity or heat discharge from the device igniting the surrounding volatile gasses, powders, and liquids.  Explosion proof applies to a device enclosed in a case that can withstand a gas or vapor explosion.  Should there be an explosion, it will be contained within the enclosure.

Interface offers products with different IP ratings, including IP66, IP67 and IP68 applied to different transducers and instrumentation. Ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids.

  • IP65 – Dust-tight, protected against water jets
  • IP66 – Dust-tight, protected against powerful water jets
  • IP67 – Dust-tight, protected against the effects of temporary submersion in water
  • IP68 – Dust-tight, protected against the effects of continuous immersion in water

What is the difference between IP66 and IP68? IP68 enclosures also provide dust-tight performance against solids. However, they are also rated for significantly better defense against water ingress than an IP66 enclosure. An IP68 enclosure can withstand submersion for over 30-minutes at up to a specified water depth.

Interface also has a range of instrumentation products that are NEMA, and IP rated based on the enclosure and housing designs.  These include:

Interface Introduces SuperSC S-Type Miniature Load Cell

Interface has released its latest load cell invention, the SuperSC S-Type Miniature Load Cell. Interface’s new product is an s-type miniature load cell that offers capacities in a form factor 80% smaller and 50% lighter than other models of s-type load cells. It’s ideal for industry 4.0 applications.

The Interface SuperSC is an economical general purpose load cell with a compact design. It is perfect for all types of test and measurement applications in confined spaces and for OEM use cases with smaller product dimensions. The miniature sensor is also environmentally sealed and insensitive to off axis loading.

Designed by Interface’s engineer Raymunn Machado-Prisbrey, SuperSC comes in 12 capacities ranging from 25 to 1K lbf and 100 N to 5 kN. Six designs for international standards of measurement (metric) and six are imperial standards. They are environmentally sealed with an IP66 rating and offer high stiffness with low detection.

“S-type load cells have grown in popularity every year since their introduction in 1974 by Interface’s founder, primarily due to their design features and performance for use in diverse force measurement applications.” Mark Weathers, VP of Advanced Manufacturing and OEM Products

Due to its high capacity and compact housing, it is an ideal sensor for weighing and test machines, as well as in OEM product designs for ongoing performance measurement and monitoring. S-type load cells are some of Interface’s most popular products. The new product release of the SuperSC represents the next generation of the versatile Interface Mini product offerings.

“The SuperSC is the next generation of s-type load cells with the Interface’s distinguishable high quality, accuracy, reliability, and range of capacities, while also offering a more compact design and options for customization and embedding into products and machines,” said Mark Weathers, VP of Advanced Manufacturing and OEM Products

The Interface SuperSC is manufactured at Interface’s headquarters in Arizona. It has accessories and different build options, including a high-temperature rated version, fatigue rated, special calibrations, and it also can be pre-installed with rod end bearings. Interface also plans to introduce a submersible, IP68 rated version and a model specialized for load compensation.

Superior S-Types Webinar Recap and New SuperSC

Interface hosted a new online seminar, Superior S-Type Load Cells, to highlight the different models, capabilities, and features of this popular type of force measurement transducer. It also provided a terrific opportunity to showcase one of Interface’s latest inventions, the new SuperSC S-Type Load Cell.

Interface’s Raymunn Machado-Prisbrey, Randy White and Mark Weathers detail important topics during this essential force sensors event. The presentation focuses on various S-type products, an engineering perspective, use cases and applications, along with the news of the SuperSC product release.

S-type load cells, sometimes called s-beams, get its nomenclature from the “S” looking model of the load cell. The classification of this type of load cell is considered a miniature sensor. They are part of Interface’s extensive line of Mini Load Cells.

One of the clear advantages of this load cell, that Interface brought to market in 1974 through an invention by our founder Richard F. Caris, is that it can be used to measure tension and compression.

Common Standard S-Types Use Cases

  • Controlled tension and compression measurement applications
  • Proof loading
  • Fatigue and high cycle count tests
  • Material testing
  • Suspended weighing and platform scales
  • Rigs, cranes, and hoists
  • OEM systems
  • Test machine integrations

The “S” shaped load cell has mechanical attachments on the top and bottom. The strain gage bridge is located at center. Interface uses a Wheatstone bridge with proprietary strain gages in a bending configuration. This offers a more efficient inline package versus standard bending bridge sensors for improved off axis insensitivity.

As detailed in the webinar, one of the biggest benefits is the scalable design that can accommodate a wide range of capacities through material and dimensional changes. S-types gained their popularity with requirements for small form factors and precision. They are now some of Interface’s top 10 products.

Engineers and testing labs prefer Interface’s s-type sensors for:

  • Proven load cell form with Interface’s strain gages
  • High accuracy
  • Size and much smaller than typical load cells
  • Value and cost-effective solution
  • Flexibility to fit in limited spaces
  • Easy to integrate
  • Universal for tension and compression testing

S-types are used inline during loading. They feature threaded mounting holes, providing stability and accuracy in measurement. They are not designed to be used for moving or rotating test objects. S-types are used in individual use cases for testing rigs and machines, as well as OEM solutions embedded into a product for continuous measurement and feedback.

Interface has a wide range of specialized miniature s-type load cells including:

  • Sealed
  • Micro-size
  • Fatigue-rated
  • High-temperature ratings
  • Low height
  • Overload protected
  • Intrinsically safe

You can watch the entire online event here. You will be the first to preview the official launch of the SuperSC and how it is modern design, superior performance, and low cost are ideal for OEM solutions. Randy, Ray and Mark detail tips, FAQs and some innovative applications for s-type load cells.
