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.
