What is New in Custom Solutions

Here at Interface, we make it a priority to adapt to the needs of our customers in any way possible. Each year we gather vast amounts of data and feedback to address changes in the marketplace and advancements in technology. Often, this comes in the form of new product releases developed specifically with our customer’s most significant needs in mind. However, new product releases take time for development, testing and release. When customers need to address a challenge quickly, we turn to our innovative custom solutions team.

No matter the project, chances are there is a customized force measurement product to fulfill the requirement. We work directly with our customer’s engineering and testing teams to understand the challenge and offer alternative solutions to off-the-shelf products. Our dedicated engineers and measurement experts, along with supporting company resources, and advanced engineering lab give Interface the competitive advantage to make any force measurement application work with what we have to offer.

We provided a brief overview of our custom solutions offerings and process a past blog. Today’s post provides an update on what’s new in custom solutions:

New Custom Solutions Offerings

Among the most significant changes to custom solutions is our growing engineered to order offerings for OEM customers. To best serve these customers and testing engineers with premium and affordable force measurement solutions for use in components or products, Interface now offers engineered to order capabilities for the masses. Engineered to order means Interface can deliver force and torque measurement solutions from our massive catalog that are modified to meet the features, specifications, and cost that our customers require, while still retaining the premium accuracy, quality and reliability Interface is known for across every industry we serve.

Another exciting capability that Interface has recently added is the addition of more digital instrumentation communication options for collecting data from our products. We’ve added Models INF1 and INF4 signal conditioners with field bus capability that include CANopen, DeviceNet, CC-Link, Profibus, Profinet, Modbus, and EtherCAT. By adding this capability, our products can interface with networks that customers already have installed in their facilities.

Custom Solutions Applications

Interface customers continue to turn to our experience Custom Solutions Engineers to build systems that utilize a range of sensor technologies, communication devices and even frames and cases to provide a complete structure.  This includes a growing demand for uniquely pairing force and torque components that work remotely through wireless and Bluetooth technologies as well as delivering entire testing units that re mobile or can be used in the field. The possibilities are unlimited with the amount of products Interface in our catalog, including the possibilities of using new designs.

Every year we engage in a host of unique custom solutions projects with our customers. We would like to share of a few of our favorites with you.

Airplane Maintenance – Wireless Customization

When an airplane comes into the shop, engineers often must jack it up to perform maintenance. When you lift a plane, there is always a risk because you can’t put too much stress on the wings and fuselage. To ensure that the maintenance team members weren’t stressing the plane beyond its limits, Interface developed a solution to measure the lifting force of each individual jack used to lift the plane. The solution included a number of Interface Model 1200 Series Load Cell that would transmit the forces applied back to a base station. However, the customization came in the way data was transmitted to the base station. Typically, wires are used for transmission, but in this case, there were 21 load cells used on the lifting equipment. To avoid having 21 wires get in the way, Interface added custom capabilities to the 1200 series to allow it to communicate with the base station wirelessly.

Crane Application – Custom Programming

Lifting heavy objects can be a dangerous job for onsite workers, not to mention, pushing a large industrial crane too far can result in expensive damages and downtime. Therefore, when an Interface’s industrial customer needed to intelligently monitor a crane in the process of lifting, we helped create a custom program to do so. The custom application included a model 1280 and force measurement activated program. Whenever the crane was nearing a weight that was unsafe, an alert was triggered based on the force measurement reading that could either sound an alarm or shut the system down. This created an automated safety system using force data.

Additional Custom Solution Applications and Use Cases are available here. 

Custom solutions are key to Interface’s broad offerings that we provide when off-the-shelf solutions don’t provide exactly what is required. Our design engineers and manufacturing team is ready to work directly with our customers to provide a solution that is right for your project. To learn more, visit us at /custom-solutions/.

Dimensions of Multi-Axis Sensors Virtual Event Recap

The Interface ForceLeaders hosted forums are designed to answer frequently asked questions from testing engineers and product designers about new technologies and uses cases. In our recent virtual event, Dimensions of Multi-Axis Sensors, we discussed the considerations for these types of sensors, the test and measurement benefits, products Interface offers and various applications.

Interface recognizes that there are growing demands for multi-axis sensors.  In our hosted event, Interface’s Brian Peters kicked-off the conversation by highlighting benefits and reasoning for the use of these types of sensors, including answering some common questions. We’ve provided a recap of the event below or you can watch the event here https://youtu.be/zua1lvTh488.

What is Unique about Multi-Axis Sensors?

Multi-axis sensors have additional bridges to provide output signals for varying axes or types of mechanical loading. They are designed to measure a multitude of forces and moments simultaneously with a single load cell sensor. Fundamentally similar to other force and torque sensors with strain gage bridges bonded to machined “flexures,” each bridge typically defines a measurement axis. 

There are multiple configurations of 2, 3, or 6-axis options.

  • Axial + Torque
  • Axial + Shear
  • Axial + Moment
  • All 6 degrees of freedom

Should You Use Multi-Axis Sensors?

The largest factor to consider is the accuracy of your test model. In many test applications using standard load cells we often notice side or eccentric load, which can skew your data. While many Interface load cells, particularly mini load cells, have been designed to reject indirect loads, nothing can handle side and eccentric loads quite like a multi-axis sensor. Dedicated multi-axis designs are typically more balanced axis capacity limits with discrete signal outputs. Composite signal outputs are common in 6-axis models.

What are the Benefits of Multi-Axis Sensor Technology?

There are a number of benefits to using multi-axis sensors in addition to accounting for and accurately measuring or rejecting side and eccentric load. These benefits include:

  • Consolidate measurement signals, conserve test space
  • Measure unwanted system crosstalk
  • Quantify reaction loads through test article on “non-measure” side 
  • More successful fatigue testing through setup and load verification
  • More data, more understanding, more complete picture

What Considerations Should Engineer Make When Using Multi-Axis Sensors?

If you’ve made the decision to utilize a multi-axis sensor in your test model, please note the following considerations:

  • System-level loads and geometry
  • Maximum loading conditions
  • Chosen capacity is adequate for measurement loads as well as potential peak or extraneous loads
  • Choosing the right sensor based on primary axis measurements

Interface Multi-Axis Sensor Products

Ken Bishop details various types of multi-axis sensor technology from Interface during the highlighted ForceLeaders event you can watch here.  Interface offers a wide range of multi-axis sensors, including 3-axis, 6-axis, axial torsion and 2-axis versions. The product options give you the ability to measure forces simultaneously in three mutually perpendicular axes, with the 6-axis load cells also measuring torque around those axes.

AXIAL TORSION LOAD CELLS

Interface’s axial torsion load cell is used for measuring both torque and force in a single sensor. Typical applications of its axial torsion transducer include bearing test and material test machines. The features of our axial torsion load cell include minimal cross talk, extraneous load resistance, and the load cell is fatigue rated. Customers can also add the following options: an integral cable, compression overload protection, and connector protectors.

2-AXIS LOAD CELLS

The Interface 2-Axis load cells can measure in two directions, X and Y simultaneously. It is commonly used in applications where dual-axis measurement is important in design and testing. They are effective for applications that measure lateral forces and the narrow design fits into compact areas.

2-Axis Interface Products:

3-AXIS LOAD CELLS

Interface’s 3-axis load cell measures force simultaneously in three mutually perpendicular axes: X, Y, and Z – tension and compression. Each axis provides a unique mV/V output and requires no mathematical manipulation. The 3-axis load cell is built to minimize eccentric loading effects and crosstalk between axes. We offer five different models in its 3A Series 3-axis load cell designed for a wide variety of capacities. They are compact in size, provide 3 full bridge mV/V outputs with an IP68 option.

3-Axis Products:

6-AXIS LOAD CELLS

Interface’s 6-Axis Load Cell measures force simultaneously in three mutually perpendicular axes and three simultaneous torques about those same axes. Six full bridges provide mV/V output on six independent channels. A 36-term coefficient matrix is included for calculating the load and torque values in each axis. An 8-channel amplifier with a USB PC interface is also available which simplifies data analysis. The company offers five different models of 6-axis load cells for a wide variety of capacities. In the end, they provide more data, accuracy, are very stiff and cost-effective for a wide range of testing options.

6-Axis Products:

Keith Skidmore, an application expert at Interface, outlined a number of use cases spanning across multiple industries. They included testing programs using multi-axis sensors in automotive, medical, aerospace and defense, consumer packaging and more. Some of the application notes discussed during this recorded event include:

  • Wind tunnel testing
  • Aerospace structural and fatigue testing
  • Computer model validation
  • Friction testing
  • Medical device: ball socket testing
  • Prosthetics
  • Robotic arm
  • Hydrofoil
  • Seat testing

Faces of Interface Featuring Ken Bishop

From the very beginning, force measurement has been a major part of Ken Bishop’s life. Growing up in Anaheim, California, his father worked for a company called Ormond, Inc., which produced load cells, rocket thrust stands, weighing products and scales. He got to know the people his father worked with and the cool technology they were working on. Therefore, it was no surprise that Ken would follow in his father’s footsteps shortly after graduating high school and working for Ormond himself.

Ken worked with his father at Ormond for five years. He held positions as a driver, an assembler, and then eventually worked his way into a technical management position. After Ormond, he took a brief break from the force measurement industry to join the expanding computing field. He worked at General Micro Systems, where he focused on single board computers. However, his true calling pulled him back and he rejoined the force measurement industry when he was hired at Sensortronics.

Sensortronics then became the first load cell company acquired by Vishay in 2002. Vishay is a global manufacturer of semiconductors and passive electronics and in the early 2000s they would end up acquiring three more load cell manufacturers after Sensortronics. Ken’s job became to work as a team member to consolidate the four companies in the Americas and create Vishay’s transducer group as the Operations Manager for the America’s. Ken oversaw this group for several years afterwards.

During his working career, Ken also began to focus on his post-secondary education. He took night classes for quite a while to earn several degrees. He started with an Associates of Science from Fullerton College. He then received a Bachelor of Science in Business Administration and Management, followed by a master’s degree in Business Administration, from the University of Redlands, in California.  His post-secondary education allowed Ken to excel faster in his career path.

After Vishay, Ken took a brief hiatus from the engineering world to get away from it all. He picked up and moved to Montana to enjoy the wide-open spaces and outdoor lifestyle. However, it was not long before the itch to make things returned. In 2006, Ken moved to Arizona and joined Interface.

Ken began his career at Interface on the sales team as an application engineer focused on the West territory. His job was to work with customers to deliver force measurement solutions for a wide variety of test and design challenges in the aerospace, industrial, medical, metrology and automotive sectors. He eventually worked his way up to become a senior application engineer.

During his time as an application engineer and senior application engineer, Ken realized that there were many customer challenges that could not be solved with an off-the-shelf solution. While Interface had worked on custom projects previously, there was no official department to head up the growing demand for custom solutions.

When the department was created, Ken was given the opportunity to become the custom solutions director. He jumped at the opportunity and created a solutions team that could meet the growing demands of Interface’s customers for systems and specialized products. Ken leads the development of custom force measurement solutions designed to meet the unique challenges of an evolving technology and manufacturing ecosystem.

If all this was not enough, Ken also leads the repair and recalibration services department with fellow Interface technical service manager, Chris Brandenburg. And, he has spent some time working on the marketing team. Ken has truly done and seen it all in the force measurement industry.

Interface Solutions for Robotics and Industrial Automation

As the manufacturing world continues to push towards the 4.0 Industrial Revolution, critical technology is necessary to ensure facilities are running as efficiently as possible. With advancements toward fully or semi-autonomous factories and robotics, manufacturers need to have total trust in their hardware and software to perform with precision in the assigned tasks. This requires collecting accurate and real-time data to constantly monitor every aspect of the facility’s technology and production.

In the development of robotics used in industrial automation, our Interface Multi-Axis Sensors are often used to test the multi-directional movement and force of robotics arms. Whether it’s a fully automated or semi-automated robotic system, manufacturers need to be able to ensure the complex movements and actions of the robotics arm are optimized to take on very precise jobs. These types of robotics are often used for projects that are too precise for the human hand.

Industrial automation and robotics are creating a more efficient manufacturing process, which will help to churn products out more quickly and lower costs. However, to optimize these processes, it’s critical that we trust the hardware to operate autonomously and that we have systems in-place to identify malfunctions quickly.

Interface plays a critical role in robotics and industrial automation by providing our customers with highly accurate load cells and torque transducers to measure and collect data on the force and torque that these machines are exerting. Interface force measurement solutions and products are involved in the testing of the machines before they hit the production line, and in some cases, our products are also installed directly on the machine to allow users to monitor the force in real-time.

One industry that has a high demand for our products is the consumer packaging industry. Many of the processes involved in the production line of a consumer packaging plant have utilized automation for a long time.

For instance, beverage companies that sell bottles of water or soda utilize machines that cap the product all day long. Hundreds of thousands of bottles go through the capping process on the production line daily. If there are any issues with the torque applied in the capping process, the beverage company could see heavy losses because the bottle could be damaged from over torquing the cap, or the beverage could leak during the shipping process if the caps are under torqued. To avoid these loses, the machines are optimized using a torque transducer.

Torque transducers provide data during the testing process to help the machine manufacturer get the force exactly right for the capping process. The torque transducer can also stay installed on the machine so that the beverage company can continuously monitor the torque of the machine and stop production before damages occur if there is an issue.

Interface offers nearly 50 types of reaction (static) torque transducers and rotary (dynamic) torque transducers. All of our torque transducers are precision-machined and use our proprietary torque sensors for the most accurate data possible.

Another common automation use for force and torque measurement products is in the automotive industry. Automation in this industry has been used for some time increase production of cars.

Two examples of how Interface load cells and torque transducers play a role in the automobile production line is with seat durability testing and bolt fastening.

For seat testing, we had a customer use an Interface Multi-Axis Model 6A68C 6-Axis Load Cell to identify previously unknown bending forcing that could negatively influence their testing process. This allowed the customer to redesign their testing fixture to eliminate the bending moment and more accurately perform the durability testing.

For bolt fastening, we installed an Interface Model LWCF Clamping Force Load Washers along with Interface Instrumentation to monitor the force being applied during bolt tightening. This helped the customer avoid over tightening bolts, which could damage the product in the process.

For a more in-depth overview of both applications, please check out our application notes:

Force measurement products are a critical technology in the testing and monitoring of automation equipment.

Finding the Center of Gravity

Even after more than a half-century in the force measurement industry, Interface continues to find new  and innovative use cases for our precision products.

Recently, we were approached by a customer who needed help finding the center of gravity in order to optimize weight distribution and balance for a product in development. Our outstanding team here at Interface put our heads together to develop a unique testing method to help discover this critical data point.

One of the most rewarding experiences in managing our custom solutions is learning about a new customer challenge and developing a novel solution to address it.” Ken Bishop, Director of Sales and Customer Solutions, Interface, Inc.

For this specific use case, the customer had a cylindrical tank filled with material for which they needed to find the center of gravity. Because we were able to calculate the distance of the tank, we were able to understand the weight distribution and create a test to find the center.

The center of gravity of an object is calculated when the weight of the given object is concentrated into the center of the object. This is determined by measuring the weight seen by each of the four legs.  If the weight is distributed evenly, the material is in the center location.  This center location can also be referred to as the origin.

Utilizing a Model 1280 Programmable Weight Indicator and Controller, which is highly customizable instrumentation for any application, we were able to write a program to achieve our goal. We then placed two Model 1211 Standard Precision LowProfile® Load Cells on each end of the rack where the tank resided, using four load cells in total. Because we knew the distance of the object and had load cells to measure the weight at both ends, we were easily able to calculate and identify the origin point on the tank. In this case, the center of gravity.

Ken noted that during his tenured career at Interface, this was the first time he and the team had been tasked with finding the center of gravity in relationship to the distance for an object. As Interface’s team thought about how to develop the custom solution, they also considered additional applications in which this information could be beneficial.

The result of this successful test and measurement application, Interface considers the center of gravity analysis as a beneficial test to optimize flight performance of an airplane. This is important when there is that instant that a plane is not flying at max capacity. There may be open seats all around you, but in order to keep weight distribution in balance, the attendants may need to limit which seats are occupied during a flight. If planes were equipped with this type of sensor technology to calculate center of gravity, they could more evenly distribute weight and ensure optimal performance.  This same type of application can apply to any vehicle that moves on land, air or water with people or cargo.

SEE THE APPLICATION NOTE FOR CENTER OF GRAVITY TESTING

In the growing demands for urban mobility, unmanned vehicles and drone technologies, this type of testing application can help with vehicles, aircraft, space vehicles, boats and more with performance and safety.

Force measurement has a limitless number of applications to improve performance, maximize efficiency and even work in real-time to provide smart decisions. At Interface, we are discovering new ways to redevelop our load cell, torque and multi-axis sensor products for customized solutions to meet the growing demands for innovation.

Interface works with a wide range of industries, including aerospace, automotive, medical, metrology and industrial automation by teaming up to create unique use cases and applications that require our custom force measurement solutions. If you have a unique project that requires a custom solution, please visit the custom solutions page on our site at /custom-solutions/ or contact us at 480-948-5555.
