Setting the Standards in Innovation

Interface continues to advance our business to meet the growing demands and requirements of our expansive line of products. As it pertains to product development, the focus is heavily placed on innovating to enable our customers to depend on Interface solutions for evolving technology trends to design and test next-generation products. This fundamental prioritization at Interface over the past decade is centered on the way we serve our customers and by enhancing our product development process.

How does Interface take a customer challenge or key technology trend from an idea to a scalable product? 

Interface does not follow a standard product development process with a team dedicated to coming up with new ideas. New product development is a culmination of input from every facet of our company, from sales to engineers. We leverage the outstanding talent we have built at Interface across the board to identify what is next in terms of solving force measurement challenges.

New product ideas are mainly identified from three different areas:

  1. Trend Research: We are continually looking at technology trends to determine how we solve problems in an evolving technology world.
  2. Customer Requirements: Many product ideas are born from working face-to-face with customers to discover their precise needs. Occasionally, a custom product built for a specific customer will present a wider market appeal and turn into a larger product line.
  3. Product Gaps: We are always reviewing our core products to try and identify gaps in our ability to solve customer needs.

Once we have identified specific challenges that Interface can solve with a new solution, we begin to look internally to ensure that we have the right talent and expertise to deliver an industry-leading force measurement product.  If not, we may search externally for the right talent or partners to collaborate on the project.  We utilize tools like the SWOT analysis to evaluate our technical, business, and competitive position in the market.

Upon determining that the product is in high demand with our customers or in new markets, we then further define our product concept, as well as the business case for development and going to market. We perform thorough research to determine potential applications and conduct a risk analysis on the product. This is followed by a timeline for development and assigning resources to the development project.

Interface uses either an agile or phase-gate approach depending on the type of project. This allows Interface to make better decisions throughout the development process and quickly adjust when we determine there is a better or more efficient way of doing something.

If the technology we will be working with to develop the new product is something we have never worked with before, we assess the technology readiness level (TRL). This process helps to determine if we are equipped to handle the new technology or if we need to invest in additional R&D and, in some cases, expertise to carry out the project.

Following the detailed development plan, risk analysis, establishing a timeline and allocating resources to the development of the new idea, we begin the concept phase. This involves some discovery and often includes designing and manufacturing a prototype of the product, to begin testing with customers and gaining feedback for additional iterations.

These steps lead us to deciding if a minimum viable product (MVP) or minimum valuable product is the best way to proceed to market. Utilizing this approach, we can quickly develop a fully functioning product with minimal bells and whistles and get it into a customer’s hands. This also freezes the design and allows production to prepare for the product launch.

Concluding the process is a new product introduction (NPI) and lifecycle management. During NPI we are focused on two key aspects – internal planning and external communication. Our internal planning involves setting up manufacturing and educating the sales staff on the final product. External communication is the process of creating a marketing plan, developing content and data sheets, as well as planning events and demonstrations for exhibits.

During the lifecycle management phase, we are taking orders, managing service on the product, and evaluating both the product and the launch. All these initiatives help drive future product development and launch strategies for innovative solutions.

This part of the process is where our technical sales team is critical. These individuals, with strong relationships with our customers, are constantly collecting feedback and reporting back to our design and engineering teams. This helps us determine the best way to proceed in adding additional features and technology to the product.  This in turn, leads to post launch releases and enhancements to the product, which help fuel the product’s growth.

Our product development process is constantly evolving as we continue to add new capabilities and work towards providing our customers with an all-encompassing suite of force measurement solutions to handle the challenges of today and into the future. Interface has thousands of products, standard, modified, and custom.  It is critical in our approach to stay ahead of trends, predict needs, and most importantly listen to our customers to make sure our products are exactly what they need from a leader in force measurement.

Multi-Axis Sensor Applications

For more than 50 years, Interface has proven itself as the premier provider of load cells, with the most accurate and reliable products on the market. As the technical landscape has evolved, we have invested heavily in new technology to suit the growing needs of our customers. One of the most important innovations we’ve brought to market over the past few years is our lineup of wide-ranging multi-axis sensors.

Interface Multi-Axis Sensors are designed to measure a multitude of forces and moments simultaneously with a single load cell sensor. These sensors provide multiple bridges that precisely measure the applied force from one direction with minimal crosstalk from the other axes.

Multi Axis Sensor 3AXX 3 Axis Load Cells -

Interface Multi-Axis Sensor 3-Axis Load Cell

Interface offers 3-axis, 6-axis, and axial torsion load cells, which provide the ultimate in force and torque measurement. We can measure forces simultaneously in three mutually perpendicular axes, with the 6-axis load cells also measuring torque around those axes. In addition, we offer multiple data acquisition and amplifier systems which make graphing, logging and displaying data easy enough for any experience level.

Our customers work in a wide variety of industries, and we are continually seeing new applications of our range of multi-axis sensors. These sensors are used in aerospace, automotive, medical and more.

The following application examples provide a clearer picture of the benefit of this force measurement and sensor technology.

Rocket Structural Testing – In rocket and aerospace testing, there are a million different considerations to ensure a proper launch. One of the vital force tests that need to be conducted is on the connection between the rocket and the launch vehicle. There are force and moment in multiple directions at the connection point. Interface Multi-Axis Sensors can be used to test not only the strength of the connection but also ensure a safe disconnection between the rocket and launch vehicle.

Drone Testing – One of the most interesting applications of our multi-axis sensors is in the drone industry and in areas of urban mobility. Our sensors are used to test the drone’s rotor. The drone will always pull on the sensor to create the most significant force; however, there is also a slight amount of moment that needs to be accounted for. We were able to calibrate a semi-custom load cell to account for both the large pull force and the small moment force to provide the most accurate data possible.

Prosthetics – Another impressive application of our multi-axis sensor technology is in the medical industry. We helped to test the multiple force and torque data necessary to build a strong and reliable prosthetic knee joint and spine. Each of these prosthetics has multiple motions on many axes. To measure the quality of the prosthetic and to ensure it doesn’t fail when implanted in a patient, medical OEM’s need to be able to collect data on each of these axes simultaneously.

The need for measurements on multiple axes has grown over the last couple of years because of the desire to use big data to create better products. Interface Multi-Axis Sensors provide the accurate measurements our customers need and the ability to collect those measurements simultaneously, which has created a significant boost in efficiency.

Brake Testing with Interface Bluetooth Solutions

Automotive testing for brakes requires trust and accuracy in ensuring safety is first and foremost for any driver and passenger, no matter the amount of applied force. Automotive safety is most important for all manufacturers in the industry.  Interface products used in the test and measurement applications for brakes are most frequently selected based on quality, reliability, and precision.

In this application note Interface outlines how it was able to help a customer measure brake pedal force using its new Bluetooth Telemetry System (BTS) and a BPL-300-C Brake Pedal Load Cell.

Interface was asked to outline how a customer could help in measuring brake pedal force when the pedal is pressed during automobile testing, preferably with a cordless solution.  There are two critical components that Interface recommended based on all the customer’s requirements.

BPL-300-C Brake Pedal Load Cell:

  • Interface’s Brake Pedal Load Cell has the lowest nonlinearity and hysteresis of any brake load cell available.
  • It features ultra-low height and low sensitivity to off-axis loads.
  • It mounts directly to the pedals with included straps and has interchangeable mounting plates.

BTS-AM-1:

  • The BTS-AM-1 is a Bluetooth Low Energy (BLE) strain bridge transmitter module that provides access to high-quality measurements on a mobile platform such as a phone or tablet.
  • The delivery mechanism is BLE which utilizes the flexibility and availability of Bluetooth receivers while maintaining the low power requirements of embedded systems.
  • Features high measurement resolutions, simple integration into IOS and Android Apps, 30 to 90 m range and advanced security.

Noted in the application use case, as the pedal is pressed, force is measured by the BPL-300-C Brake Pedal Load Cell. Results are transmitted by the BTS-AM-1 Bluetooth Low Energy (BLE) Strain Bridge Transmitter Module to the BTS Toolkit Mobile App and displayed on a mobile device.  As the pedal is compressed, the force measurement data is transmitted through the BTS-AM-1 to the user via the BTS Toolkit Mobile App

How it Works:

  1. The Interface BPL-300-C is securely mounted on the top of the brake pedal.
  2. The load cell is connected to the BTS-AM-1 Module.
  3. The BTS-AM-1 Module transmits via Bluetooth to the BTS Toolkit Mobile App.
  4. The BTS Toolkit Mobile App runs on iPhone or Android devices.
  5. The brake test is performed and results are displayed in real-time on the BTS Toolkit Mobile App.

Using the Interface BPL-300-C Brake Pedal Load Cell and BTS-AM-1, the customer was able to execute the brake pedal test and measure the results in real-time Bluetooth technology. The force measurement data was simultaneously displayed and graphed for accessibility and readability.

Strain Gages 101

A strain gage is a sensor that varies its resistance as it’s stretched or compressed. When tension or compression is applied, the strain gage converts force, pressure, and weight into a change that can then be measured in the electrical resistance.

At the heart and soul of every load cell is a strain gage. This is the pinnacle technology that allows engineers to collect and analyze force data. In the industry, it is known as force measurement.

Strain gages are made through a photo-etch process using a flexible backing and a very thin foil. The way a strain gage works is when the backing and foil stretches or compresses, resistance goes up and down respectively. We know this as force. Think of stretching like a three-lane highway switching to two lanes, and vice versa for compression with two lanes going into three. As the load cell’s internal strain gage experiences force, it sends a signal with a precise measurement of the amount of force it’s experiencing.

There are many different types of strain gages for a variety of environments and force measurement needs. The major difference in strain gages is the base material used in the manufacturing process. Different materials are used when a load cell needs to perform optimally in a variety of temperatures, humidity levels, and elevations. Matching the correct strain gage and a load cell to the customer’s needs is critical to accuracy.

“Here at Interface, we pride ourselves on developing the most accurate force measurement tools, and it starts with our proprietary manufacturing of the strain gage.”  Scott Dunne, Production Engineering Manager

More than 52 years ago, when our founder Richard F. Caris started Interface, he purchased over a mile of foil, which is the base material used in strain gages. Caris understood the only way to ensure Interface customers received quality results from their force measurement products was to control every aspect of engineering design, product development, and production.

The key ingredient to our precision accuracy and reliability is the fact that we have vertically integrated the entire manufacturing process from design to production and have a deep understanding of the materials necessary to suit every client’s need for optimal results

Many load cell makers purchase their strain gages from a third party. This means there’s more variability in their manufacturing process and you often find the variances in their materials clash and diminish the accuracy, or they are not correctly suited for the customer’s project requirements.  Interface makes all their own strain gages.

We have learned everything there is to know about strain gage manufacturing and can guarantee the quality of our load cells in any environment based on this tenured expertise and having manufactured and calibrated hundreds of thousands (ok, millions) of force measurement devices. And here’s a fun fact, although we’ve manufactured hundreds of thousands of load cells and strain gages, we haven’t even used half of the original mile of foil we purchased in 1968. Good product managed well can go a long way!

Compression Force Testing 101

Compression is a type of force that we apply every day often without thinking and compression is intensely tested in many of the products we use on a daily basis.

Compression force is defined as the energy generated from compressing an object or substance. Compressive force is simply the direction of the force applied to the load cell. The compressive strength of materials and structures is an incredibly important engineering consideration in both designs and build.

Whether you are clicking the keys on your laptop at work or slamming on your brakes to avoid an accident on your morning commute, you are using the compression force. Testing of the compression force is essential in developing a reliable and sturdy product that can withstand the pressure applied to it many times over. Often, safety is at the core of compression testing.

Load cells incorporated into the testing process work by measuring the pushing force of an application on a single axis. The strain gage compresses to measure the load applied. The deformation of the strain gage provides the measurement data. Application tests measure the total compression force the products or structures can handle, as well as the effects of compression over time through stress tests. In both cases, original equipment manufacturers (OEMs) need accurate measurements to guarantee their products can withstand compression in the short and long-term.

Interface supplies a variety of compression-focused load cells and accessories for all types of applications, both for test and measurement, as well as for inclusion in originally manufactured products and solutions. These compression load cells are often used in vehicles, industrial automation, aerospace, and defense industries. Applications are wide-ranging, from testing the impact of drones dropping packages to the material strength of bridges during an earthquake. Interface load cells are highly-rated to provide the most accurate data and reliability over time, which is why engineers rely on Interface compression-only load cells.

Here are a few of the compression load cells available from Interface:

1601 Gold Standard® Calibration Compression-Only LowProfile® Load Cells – Interface’s Gold Standard® Load Cells are designed for calibrating other load cells. The 1601 load cell is compression-only and has options available for a second and third bridge and overload protection.

1201 Compression-Only Standard Precision LowProfile® Load Cells – The Interface 1201 LowProfile® load cell provides a “compression-only” force measurement. Its spherical-shaped top surface helps provide minimal off-axis loading. 1201 is our most popular load cell designed for static applications and has a higher output than most competitive load cells.

2101 Dual Range Standard Compression-Only Load Cells – The Interface Model 2101 consists of lower and higher capacity model 1200 type load cells which are stacked with overload protection built into the lower capacity load cell permitting the high resolution to be obtained at both low and high levels of capacity. The Model 1201 is LowProfile® moment compensated.

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.

Why Interface Load Cells Stand Out from the Competition

As you might expect, there’s a lot of care and attention to detail in our product development methods that allow Interface to create the most accurate and reliable force measurement tools on the market. Honed over our 51 plus years in the manufacturing of force measurement products, we have among the most refined and thorough processes in the industry. Today, we are going to reveal one of the unique testing processes in our LowProfile® load cell development which sets us apart from the competition, by a landslide!

It’s no secret, Interface LowProfile load cells are reliable and offer repeatable results. What isn’t widely known is this is because of the product’s overall capability to handle loads with minimum error due to misalignment. In plain English, these load cells are very forgiving to general misalignment when they are installed into the application. Why? Because of a process called moment compensation. This is one of the primary differentiators from other pancake load cells in the marketplace.

Moment compensation is one of the many production tests we run on our LowProfile load cells to guarantee minimal influence from off-axis loads known as “moments.” We compensate for moments by hanging a weight from a fixture and rotating it around the LowProfile load cell. The offset weights go around and take readings at specific locations. The computer records the data and identifies the highest readings and locations. The operator then modifies the geometry of the material from the beam to make the beamless stiff. Once this process is completed, we go around and repeat the process to confirm results until the product passes the specification criteria.

Moment compensation is performed on every individual Interface LowProfile load cell and most other Interface load cell models to ensure repeatability and accuracy. This is a big deal in the force measurement industry because most load cell manufacturers don’t test and compensate or have a specification for eccentric load sensitivity like we do.

Interface takes these extra steps because we understand that as product development becomes more complex, the margin for error gets smaller and smaller. Moment compensation also helps to maximize the operating life and minimize performance errors. With Interface LowProfile load cells, customers know that every step in our design and development process is conducted to ensure the premium quality which exceeds their needs and quality expectations.

Included below are two examples of how our products were used to help our customer’s test and measure “real life” applications.

Harness Durability Testing

A customer came to us needing to test the load and durability factors of harnesses used by workers to carry heavy loads or those used in sports equipment. We developed a drop test apparatus using an Interface Model 1200 Load Cell. The apparatus dropped a humanoid dummy outfitted with the harness from various heights to measure the force generated during sudden stops at maximum cable extension. These tests helped our customer develop harness limits which inform users on unsafe loads.

Figure one: Interface drop test apparatus using the Model 1200 load cell

Prosthetic Load and Fatigue Testing

Medical hardware engineers are among the largest users of T&M equipment because of the stringent regulations in the industry. Interface developed a new solution to test heavy loads on prosthetic limbs to certify them for falls, accidents and athletic movement. These stress tests determine the expected lifespan of prosthetic components under normal usage.  Our solution involves a static load test apparatus with an S-type load cell attached to a hydraulic actuator which applies and measures cyclic loads. These tests help our customers determine whether prosthetic materials and designs will withstand the rigors of daily use and occasional high-load situations.

Figure two: Load test apparatus with an S-type load cell attached to a hydraulic actuator  

What we find most exciting about the T&M industry is continuous innovation, perhaps it is the “engineer” in us.  We like to solve, create, build, imagine and challenge ourselves. There are a wide variety of new applications we see every year, and yet many applications are unique.

Those that are in the test and measurement field help to guarantee product safety, reliability and longevity. Therefore, the tools they use are critical to the confirmation of their work. That’s why Interface builds products that reliably and consistently gather high-quality, accurate data for any application.
