Interface’s Keith Skidmore recently detailed the growing demands for more data in the product development process to create better products in the February 2023 edition of Quality Magazine. In his contributed article, Measuring Force Data in Extreme Conditions, he expertly highlights how this demand comes with the added requirements for measurement and sensor solutions that can perform in any condition.

As makers of products, machines, and components can attest, they need more testing and performance data to make critical design and smart production decisions. The added requirement to secure this data with precision, requires quality measurement solutions that can perform under extreme conditions.

Interface has long been attuned to these demands, with an increasing product line of ruggedized products. These products, including our submersibles, intrinsically safe and stainless steel load cells help to fulfill the requirements. Examples of these products include:

Noted in the article, Keith writes: As technology has progressed, test and measurement systems are becoming more advanced and capable for a wide variety of applications and industries. This is because manufacturers want more data in the product development process to create better products, and they need solutions that can perform in any condition, especially when running field testing. This is increasingly important in force measurement as real-world testing is paramount to a safe and reliable product. And with the need for real-world force testing comes the need for sensors that can work effectively in hazardous environments including rain, wind, underwater, explosive environments, and exposed conditions.

Faces of Interface Featuring Scott Whitworth

Our Faces of Interface features the masterfully creative force behind the Interface brand. If you’ve ever downloaded an Interface product brochure or spent time on the Interface website, chances are Scott Whitworth, Interface’s creative services manager, played an important role.

Scott puts together complex product details for T&M pros, develops visual stories with digital content, and helps us keep track of thousands of offerings – one at a time! This is a story about Scott’s journey from film to the video game industry and even teaching before finally joining Interface.

Growing up, Scott was always interested in art and filmography. He pursued creative endeavors, such as a degree in the film industry at the Arts Institute of Phoenix, where he also took some traditional painting and sculpting classes. During his time in school, he started to pick up graphic design skills as well. These talents led Scott to begin his career in the film industry at a company called Digital Domain. In this role, he did digital effects for several different films and commercials.

He then moved to Phoenix, where he worked for a company called THQ. At THQ, Scott began in the film and television division where he worked in animation. Two years after he started, the company closed the film and television division and offered Scott a position in the games division. Scott remained with THQ for eight years doing 3D modeling and design.

From 2008 until 2015, Scott worked as an independent creative resource across several creative disciplines for many clients. And then an old colleague brought him back to Arizona and back to the Art Institute working a teaching job. He enjoyed his freelance work but wanted to get back into the corporate world, which ultimately led him to Interface.

Scott started in graphic design for Interface to help bolster our marketing footprint. He quickly learned about the load cell industry and all the customers that utilize sensors. Growing up in Michigan, his grandfather made parts for the automotive industry, so he was familiar with some of the technical intricacies and use cases. With a naturally technical mind and blended with a passion for creative works, he was a perfect fit for Interface.

“The blending of technical content with design tasks is I really love about working at Interface. It provides creative freedom in my work, with the discipline of getting all the technical details exactly right.” Scott Whitworth, Creative Services Manager at Interface.

Scott’s day-to-day involves leading a agile marketing team and overseeing all branding and creative functions, including collateral material, data sheets, website design and supporting the development of creative assets for our global network of sales partners. He plays a big role in creating continuity amongst all of Interface’s marketing assets. When he arrived, there were differences between marketing materials, so he has worked to standardize and strengthen the brand into the same style. His efforts and leadership in this area has really supported a leading look and representation for Interface.

When he’s not making the Interface brand shine, Scott can be found spending time with his wife and four kids. He has three sons ages 14, 13 and 10, as well as a 2-year-old daughter. So, Scott doesn’t have time for much more than being a great dad! When he does get some free time, he continues his creative passions through 3D modeling for himself, exploring painting and sculpture and other forms of art.

Scott has worked hard to make the Interface brand standout from the competition through a wide variety of platforms We’re thankful for Scott and his many talents and are glad we got share his story.

#1 DESIGN PHASE:  Collaborating with our team of OEM experts begins at the design phase. We work together with you providing engineering support and mechanical sensor design expertise as we work together to scope out the requirements and create design drawings. It is important to connect early to ensure you have captured all the important details that are relevant to embedding sensor technologies into products. Beyond size and capacity, you will want to determine what you will measure, how it will transmit data and frequency of communications, as well as exact sensor type, material use and configurations. Do you need a miniature load cell or multi-axis sensor capabilities? Will it be a load button, S-Type or load pin that fits your specs? These are the types of questions we address in the early stages of the design process. To complete this phase, we provide prototypes of early designs and also pricing based on scale of production and timelines for delivery.

#2 TEST PHASE: The second phase of the OEM process involves a complete testing protocol, selecting materials and supplies as well as packaging requirements.  For example, do you need a sealed solution, coated, stainless? We work to define exact specifications of the sensor based on performance and producibility. We work closely with our engineering, production and calibration teams through test and simulations.

#3 BUILD PHASE: Upon customer approval, once testing and prototypes are given the green light, we move to producing the devices at scale. Building requires an orchestrated team that is dedicated to quality and precision in the build process.  We measure and track each required step in the build phase with exactness, allowing for no exceptions or error. We set schedules, define the floor plans and build the instructions to build based on your requirements. These critical steps ensure the parts are built and delivered within your scheduled requirements and our quality standards.

#4 SUPPLY PHASE:  Interface acts as your supply chain partner in the management of production, stock and delivery. We work closely with you in inventory management and forecasting.

Why Machine and Equipment Manufacturers Choose Interface

For innovators in the equipment and components manufacturing industry, data is everything. Quality data can make the difference between average and high-quality products and every bit of information gathered allows OEMs to make improvements that go a long way in performance and accuracy.

This is especially true in the design, test and evaluation of high-volume manufacturing where an increasing number of companies are implementing automation. To ensure consistent and repeatable quality, it’s important that there are capabilities to constantly gather data to monitor automated systems. If a machine is about to break or needs calibration, an automated system should be able to notify them without any human intervention.

How does an organization get more performance measurement data to improve its manufactured products? The answer we know best is with precision sensors. Sensors of all types, sizes, and shapes are being integrated into a wide variety of machines, equipment, and products to gather analytics that improve design and manufacturing. Interface is proud to contribute to this growing wave of big data requirements through our force and torque sensors.

Force sensors can be used in a number of different applications to help enable automation of certain process and systems. Essentially, force sensors are used as part of a controlled feedback loop. When a force is placed on a part within a product, the sensor can tell an electronic system to make something else happen.

As a simple example, force sensors could be placed inside of a large industrial dumpster outside of a manufacturing plant. When the dumpster nears full capacity, a signal could be sent to an automated compactor within the dumpster to make more space. It could also merely notify a waste management company to come and empty the dumpster.

Interface has worked on a number of what we call “OEM Solutions.” This term basically refers to our products that are typically high volume and have Interface sensor technologies integrated into the design and production. We often custom engineer and engineer these solutions to fit the exact requirements of the innovators and product design teams.

As a end-to-end manufacturer, we build to spec, manage the supply chain of sensors, and inventory for our OEM customers. When engineered-to-order requires thousands of products, they can rely on Interface as a trusted partner. Included below are a few examples of products that we provided our products to advance use, performance and quality. Read more about our custom OEM solutions and capabilities here.

Interface OEM Solution Examples

This first example is the design of force sensors in prosthetic limbs. An Interface force transducer provides feedback from a knee or elbow joint and tell an electric motor to move the limb in certain ways. This would allow someone without an arm or leg to have a wider range of movement and enjoy a variety of new capabilities.

Another example is the use of force sensors in the energy industry. Interface sensors can be used to optimize the process of energy production and extraction. In this scenario, a force sensor measures the rate at which the machine removes the source and provides data that tells the operator the most effective rate for getting the most most volume without overloading the mechanics. Not only does this allow for a more efficient process, it also adds another layer of safety to people and the environment. Interface was selected as the top energy solutions provider.

An interesting consumer packaged goods application example we provided a solution for included multiple Interface SPI Platform Scale Load Cells installed on a machine that filled potato chips into a bag. Force results from the potato chips are read by the load cells and sent to an ISG Isolated DIN Rail Mount Signal Conditioner. The supplier is then able to control the automated production from their command center. Using this solution, the manufacturer can determine the weight of the potato chips being distributed into their bags with highly accurate results – meaning every bag of chips is consistent in the amount of chips and total weight.

These are all examples of OEM solutions that turn data into better efficiency or additional capabilities across three industries, while there are countless other applications for OEM solutions from Interface used in consumer goods, robotics and medical devices. From automation to quality control and safety, force measurement helps manufacturers create better products and better production facilities, resulting in a great customer experience.

Interface has invested a great deal of resources into our manufacturing processes and technologies to serve this market. We’ve improved automation in our facilities to lower costs and work directly with our customers to develop the perfect force sensor for every project that can be produced at volume. Not to mention, our propensity for developing the most accurate force sensors on the market mean high quality data and results every time.

Looking Forward to the New Year

2020 has been a challenging year for most. Despite the disruption every person and industry has faced this past year, Interface continues to keep our eyes on the future. What can we do to meet our customer’s needs today and tomorrow?

One of the ways that Interface has accomplished this intense focal point is by setting our sights on the increasing number of requests for specific drawings and engineered to order force, torque, and specialized product lines. These requests provide us unique visibility in evolving product development concepts and the overall T&M landscape for the customers we serve.

Through Interface’s continued investments in R&D, analyzing the marketplace, and anticipating customer needs, we’ve identified key trends that we believe will have a significant positive impact in meeting our customer’s current requirements and preparing for future demands.

The first trend we see today is our customer’s increased focus on miniaturization. Innovation using sensor technologies continues to shrink in dimensions yet require the same or greater level of precision performance. We see this in all types of devices and hand-held technologies, industrial automation, robotics, as well as in automotive and consumer product inventions.

The trend towards miniaturization in the medical device industry has been happening for quite some time; however, the capabilities and precision requirements continue to become more stringent and demanding of higher levels of performance. For example, with trends in at-home care remote monitoring has caused medical device manufacturers to develop mobility for devices. They’re also taking diagnostic machines and turning them into a handheld version so doctors can administer medical tests quickly and efficiently at the point of care, rather than sending patients out of home for administering or tracking.

To address product development challenges related to devices that becoming more compact, Interface is engineering and manufacturing precision components that excel in confined space. We’ve already begun to address this in 2020 with the release of our ultra-precision ConvexBT™ Load Button Load Cells.

ConvexBT is a first of its kind load button load cell, providing better temperature resistance and more enhanced eccentric load rejection than other competitive products. For many years, miniature load cells categorized as load buttons have been sensitive to off-axis, eccentric or misaligned loads. This means if the load is not exactly perpendicular to the surface it is resting on, the data could become skewed or inaccurate. Interface designed the ConvexBT load button load cell to confine misaligned loads to the primary axis of the cell providing superior performance in comparison to similar products on the market. Read more about the product release here.

The next key trend we are prepared to address in 2021 and beyond is test and measurement systems that address complex and multi-dimensional testing requirements. Historically, load cells and torque transducers have addressed force, torque, and weight in a variety of single product groups. And these devices would be added to a test series with a host of other sensors or get multiple outputs through a variety of tests. More and more customers want measurement devices that include additional outputs from the sensors to account for things like acceleration, temperature, humidity, and more.

We see this in growing requests for adding accelerometers in our load cells and torque transducers. In industries like automotive, we often use a torque transducer to measure rotation with components like car engines and tires. By adding an accelerometer, the device can be used to measure both torque and acceleration. This addresses our customer’s desire to simplify their test process and it provides more data in a single test to expand use cases and applications.  As this desire for more data and fewer testing devices grows, Interface is continuing the expansion of engineered to order and customized load cells to allow for dual measurements in a single component.

This trend is closely related to the need for a complete system. Systems are often completely customized to a single project or program that provides the measurement device, instrumentation, cabling, and housing. These systems can also be mobilized with wireless components for field applications.  The group of custom solutions engineers have created multiple versions of these systems used in energy, aerospace, and T&M labs.

Despite the challenges of the last year, Interface is hyper-focused on innovation and the ability to address the evolving needs of our customers. If you want to measure it, then Interface is here to help you create the right solution to get exactly what is required for your invention, product improvement or test. How can we help you win in 2021?

Interface is a Critical Solutions Provider for OEMs

The hardware industry is rapidly making its way into taking advantage of the Industry 4.0 and Big Data eras. The idea that data insight can cut costs, increase efficiency and reduce downtime is spreading like wildfire throughout major OEMs (original equipment manufacturers) across the world. These organizations are adding more and more sensors and other data collection devices to their products to receive deeper analytics on the health and efficiency of various in-action processes.

One of the most important tools in this mix of data tracking and collecting devices are force measurement sensors. Load cells and torque transducers are being added to products across industries to not only optimize individual product processes, but also to ensure that the product remains in proper working conditions.

As an example, the aerospace industry is putting force sensors all over airplane components. Everything from landing gear to the wings may include a sensor. These force sensors can then be used to constantly collect data on the well-being of these components. If landing gear needs to be fixed or adjusted, you don’t want to find that out while your 30,000 feet in the year. You want data that helps you track performance and potential degradation over time so you can solve problems before it puts lives at risk.

To serve OEMs in automotive, aerospace, robotics, medical and consumer product industries, force measurement companies like Interface must be able to manufacture sensors in high volumes and at affordable price points. Load cells and torque transducers used in test and measurement can be reused over and over, so the demand for higher volumes is lower. However, when the sensor is integrated into the final product, force measurements manufacturers need to be able to deliver a high enough volume to meet the OEM’s demand for production of the specific product the sensor will be integrated into for continuous use.

Interface holds a unique position in the OEM marketplace for custom sensor technologies. Our decades of success has allowed us to make critical investments towards streamlining our own production and manufacturing of industry-leading components to serve OEM customers. Over the last few years, we’ve implemented better, more efficient processes and have added automation to improve consistency, repeatability and time to market. This also benefits our customers by lowering costs for large scale, continuous production to meet the growing demands and use cases in the OEM market.

A huge benefit is that Interface controls the design and development of our load cells and torque transducers. We build everything from the strain gauges to the product packaging. This allows us to rapidly iterate and customize our designs to meet the needs of a wide range of OEM customers. Our engineers work hand-in-hand with our OEM partners to design the exact requirements into our sensor technology.

This is critical to being a top solutions provider serving OEMs because force measurement products must fit the design and specifications of the OEM application, as well as potentially removing unnecessary features to fit a certain price point for volume production. OEM applications can also be exposed to more extreme conditions in industries like aerospace, automotive or medical, so the sensor might need a specific material or treatment to withstand certain environments.

One of the essential benefits we provide our customers in the U.S. is the fact that our products are manufactured in country, and our engineering, sales and support staff is also local. This enables easier communication with our customers, as well as faster shipping times. When a customer needs to adjust the specifications on a device or troubleshoot a challenge, they know that they’ll get the support they need during their own working hours.  We are extending this value globally as we continue to create solutions that meet our demands worldwide.

The demand for big data and automation is growing rapidly among OEMs. It is also one of the most competitive markets in the world. To serve our customers with unique engineered to order designs and solutions, we work every day to stay on top of manufacturing trends and find new ways to optimize production to meet their cost and volume needs.

Interface Steps in to Support Medical Industry COVID-19 Innovations

The COVID-19 outbreak has hit everyone hard and many industries are rushing to adjust to this new world. One of the industries most impacted by the outbreak has been the medical sector. Hospitals are in a position of running dangerously low on supplies and equipment to treat the influx of patients coming through the doors for vital treatment.

Fortunately, global innovators, product designers and manufacturers in the medical sector and outside the industry have stepped up to provide solutions critical to the fight against COVID-19. Some of the largest original equipment manufacturers (OEMs) in the world, such as Honeywell Aerospace, 3M, and Ford, have reallocated significant resources within their facilities to help produce medical equipment and PPE like the much needed N95 Masks.

Medical OEMs are also ramping up production on certain technology aimed at preventing, testing, and treating the corona virus. One of the most significant pieces of medical technology needed in this pandemic are ventilators. Prior to the outbreak, analysts predicted a shortage of these devices, which are needed to treat the rising number of patients. OEMs around the world stepped up to mass-produce high-quality ventilators to meet this demand.

The production of ventilators did not just fall upon the shoulders of the OEMs. Thousands of design and test engineers in coordination with manufacturing service providers involved in the ventilator supply chain also leaned in to support the demand. Interface is proud to help participate as part of the supply chain, helping essential OEMs around the world with critical force and torque testing products.

One example related to ventilators came in April of this year when SISU reached out through our representative network to T&M Instruments in Texas.  Jace Curtis worked with Interface to urgently provide our T8 General Purpose Shaft Style Rotary Torque Transducers. Jace, who represents the Interface product line, worked with a team of suppliers and testing experts to get the product design through testing quickly. This meant the transducer needed to be in-house within 24-hours. Working with Brian Peters, the product was expedited due to the sensitive nature of this requirement and delivered from our Scottsdale headquarters in the time requested.

SISU is currently designing and manufacturing the AUSTIN P51, a low-cost ventilator to aid hospitals and medical professionals in the current world-wide shortage, and they needed the torque transducers as quickly as possible to help test and verify the ventilator stepper motor.

The challenge with this project was that SISU was targeting the manufacturing of 100,000 ventilators on a very rigorous timeline and they did not have time to program a test to acquire and analyze this data. They needed to quickly set up a test correlating lung pressure to the torque of the stepper motor when the adjacent paddles squeeze the self-inflating bag. Air is then driven through a series of pressure regulators and a HEPA filter that can assist or support the human lungs when compromised.

DEWESoft USA, a company that develops and manufactures versatile and easy-to-use data acquisition systems, was charged with the development of this test system. They immediately got to work and were able to deliver a test platform capable of verifying the torque and air pressure within hours.

One of the key pieces of technology in the development of the test system was our torque transducers. The purpose of the torque transducers in the test platform was to analyze the stepper motor and gather data to ensure performance and accuracy. It was critical that the motor performed to specification, and our stainless steel, contactless T8 Torque Transducers were well-equipped to provide DEWESoft® with highly accurate, real-time data.

Additionally, not only was Interface able to overnight the T8 Torque Transducer to DEWESoft on a Saturday morning, but we were able to absorb some of the costs due to the nature of the product need and these unprecedented times. Jace Curtis was also onsite on Saturday to help assist with set-up and testing.

DEWESoft recently put together an application note and video showing the test platform in action. In these pieces, you can see how our torque transducer is used within the testing platform. Included below are links to DEWESoft’s video and application note:

Interface is proud to be an essential business in this time of crisis. It was our duty and honor to support T&M Instruments and DEWESoft in the development of this critical testing platform for life-saving ventilator technology manufactured by SISU.  It is our commitment to all our customers.  We are here to help.
