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.

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.

Watch our latest webinar to learn more about the versatile miniature S-Type Load Cells and the news about our SuperSC.


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

Faces of Interface Featuring Raymunn Machado-Prisbrey

Raymunn Machado-Prisbrey has spent his entire professional career at Interface. His first job was right out of high school, where he was hired to work on the assembly line at night. During the day he attended Arizona State University as a full-time student and after four years graduated with a degree in mechanical engineering.

After graduating, Raymunn was a shoo-in for an engineering job at Interface as he was already well-versed on all the products and knew all the people. He has held his current job as a Production Engineer for four years and continues to grow in his role.

His connection with Interface started long before he joined the company. It’s generational. While he was growing up, his dad worked at Interface and regularly brought him to company picnics and events. He got to know several of his father’s co-workers who would eventually become his own teammates. It’s this family atmosphere that Raymunn enjoys the most.

“The people are what make this job great.” Raymunn Machado-Prisbrey

Raymunn was always drawn to engineering and he knew right away that he wanted to follow in his father’s footsteps. He has a persistent fascination for how things work and enjoyed helping his dad work on cars and ATVs. He loved school and was gifted at math. Pursuing a degree in mechanical engineering was a natural fit and working at Interface aligns with his goals of personal development and life-long learning.

In his current role, Raymunn works closely with the sales team to help turn customer requirements into reality. He designs load cells and helps in the entire process of their creation. He also handles the calibration and electrical adapters for load cells, an area he earned a unique perspective from working on the calibration floor out of high school. He strives to make a positive impact on the production personnel’s job with each new design since he’s been on both the production and engineering sides of the manufacturing business.

While Raymunn is very proud of several of the projects that he has worked on while at Interface, he notes that designing custom load cells for the Giant Magellan Telescope was the coolest. The lens on the telescope itself was 8.4 meters, an incredible feat in engineering and a unique challenge for Interface.

Raymunn loves the strategic aspect of his role. He likes collaborating with a team to solve customer problems. Many of his other favorite projects relate to unique customer circumstances, where he had to think outside the box to come up with the best solution. Load cells going on mountaintops in Chile, load cells that needed to withstand a huge temperature swing, custom load cell geometry and load cells that needed to exist in a vacuum were some of the examples he cites. Raymunn loves a challenge, and it is this aspect of his job that keeps him constantly engaged and inspired.

When not working at Interface, Raymunn is an avid backpacker and loves to camp and get away from the city. He enjoys four-wheeling, target-shooting, and mountain biking. Basically, anything that involves exploring the outdoors. He also loves to travel and has recently visited Germany and Mexico with several additional trips in the works.

Interface Load Cells in Medical Applications

While quality and accuracy are always important when designing load cells, there is perhaps no industry where these factors matter more than in the healthcare and medical industries. At Interface, we take pride in creating precision force measurement solutions used in biomedical and pharmaceutical industries, as well as the manufacturing of medical devices.

We stop at nothing to provide customers with the most accurate force measurement solutions available to ensure patient safety, product reliability and accuracy in measurement.

Below are just a few examples of how Interface load cells are supporting safety in medical innovations.

Plasma Separation

Interface’s MBS low-capacity aluminum bending load cell is being used in plasma separation machines which must be calibrated for every patient in order to collect the right amount of plasma. The machine separates the blood in a centrifuge and a saline solution is pumped back into the patient. There are two load cells in each plasma separation machine, and they play a vital role in ensuring the accuracy of the process. This protects the patient’s health and well-being.

Stent Material Testing

Large testing rigs that contain approximately a dozen Interface load cells are used to test stents and heart valves that are surgically implanted into patients. The rigs subject the stents and heart valves to thousands of stress tests over months to determine their material properties. Stents stay in a patient’s body for the rest of their life, so accuracy and durability are extremely important. This application makes use of Interface’s MBP product line, which is overload protected. This product line is extremely reliable and has never had a reported fatigue failure.

Robotic Surgery

An emerging trend in medicine is the ability to perform surgery remotely using a robotic arm. Interface has been involved in the development of this technology and has created the modified custom load cells needed to enable the customer’s designs.

Designing for Medical Applications

Beyond just accuracy, there are several different considerations to make when designing and building load cells that can be used in medical applications. Factors such as traceability and the materials used are extremely important to our customers. All materials need to be certified and free of hazardous compounds. They also need to be able to withstand sterile environments where surfaces are constantly being sprayed with chemicals. There are several unique considerations and failure is not an option when it comes to devices that can directly impact patient safety.

Interface is extremely proud of our superior quality load cells and the fact that we are enabling medical innovations that are having a direct impact on improving, saving and changing lives.
