Interface’s recommended installing a 1200 Standard High Capacity Load Cell in between the aircraft testing rig and the lifting jack. The load cell can measure the load’s force safety valve when the lifting equipment opens. Results are then sent to the 9890 Strain Gage, Load Cell, & mV/V Indicator, where the customer can see it displayed in real-time. Using this solution, the customer was able to determine that the aircraft lifting equipment was working properly. Since they are ensured of its safe functionality, it can now be used on real aircrafts that need to be lifted. Read more here.

SILO GRAIN DISPENSING

A customer wants to measure and record the grain being put in and out of their grain dispensing container, as it dispenses content into a carrier truck for transportation. The customer also preferred a wireless solution. Interface suggested installing a WTS 1200 Standard Precision LowProfile™ Wireless Load Cells at the legs of the grain dispensing container. The 1200 can measure the distribution correlation of the grain as it inputted and outputted from the container. Results are transmitted and displayed using the WTS-BS-1-HA Handheld Display for multiple transmitters and logged and graphed using the WTS-BS-4 USB Industrial Base Station. Using this solution, the customer was able to log and graph the measurement results of the grain content that the silo dispenses into the grain dispensing container, and also when the grain is dispensed into the carrier truck.  Get more details here.

WASTE MANAGEMENT CONTAINER WEIGHING

A waste management company wanted to measure the capacity of their waste containers to know when it is time to dispose the waste. Interface provided Model WTS 1200 Standard Precision LowProfile™ Wireless Load Cells to be installed at the bottom of each waste container leg to measure the sum weight of the container. The real time weight data is then transmitted to the WTS-BS-4 USB Industrial Base Station with the supplied Log100 software. Using this solution, the customer was able to determine when their waste container was at full capacity to dispose of the waste, or to transfer it in a timely manner.

Interface Solutions Designed for Infrastructure Challenges

All infrastructure, big and small, needs to be designed with safety and durability in mind. Take for instance the massive amount of design, engineering and quality control that goes into a suspension bridge requires testing before and after it’s built. Not only does it need to be constructed with supreme accuracy, but it also needs to be tested and monitored constantly to ensure it’s safe for use, especially as often infrastructure projects are exposed to extreme elements.

Among the various tools and technologies used to build and test infrastructure designs, sensors play a substantial role. Interface has served infrastructure industry suppliers and customers since our founding more than 50 years ago. Force and torque measurement products including Interface load cells, torque transducers, load pins, load shackles, tension links and instrumentation are involved in a wide variety of infrastructure applications including construction and maintenance of bridges, roads, transportation systems, communication structures, water and electrical facilities, and numerous inventions that are used to build, test, support, maintain and monitor performance of these critical projects around the world.

Accuracy and reliability of Interface solutions are a key factor in measuring structures and components that are exposed to hazardous or weather-related conditions, heavy loads and constant use. Our precision load cells, rugged load pins, wireless and digital instrumentation, along with multi-axis sensors and robust torque transducers are a top choice for those engaged in infrastructure engineering projects and testing.

A few examples of how Interface products have been used on infrastructure applications over the years are noted below. The following examples are also found with many others here /solutions/infrastructure/. 

Concrete Dam Flood Monitoring

A customer was looking for a solution to monitor a concrete dam and be notified when it reached high flooding levels. Interface provided WMC Miniature Sealed Stainless Steel Load Cells with multiple WTS-AM-1E Wireless Acquisition Modules connected to the load cells. This solution proved to be small enough and perfect for measuring compression and tension on the dam. The WMC Modules are installed on the arch of the dame and transmit data and notify the customer through Interface’s Wireless Telemetry System when flooding occurs. Check out the application here.

Hydropower Turbine Generator Monitoring

When a customer wants to monitor and detect turbine generator faults in their hydroelectric power plant located on a river, Interface can provide a T2 Ultra Precision Shaft Style Rotary Torque Transducer and attach it to the turbine generator with Interface’s Shaft Style Torque Transducer Couplings. When water from the river pushes through the penstock to the outflow, it moves the turbine blades, creating electricity through the generator shaft. Torsion measurements can be graphed and logged with the 9850 Torque Transducer and Load Cell Indicator catching any unusual fluctuations and vibrations. Using this solution, the customer can monitor, graph, and log the torque measurement results of the turbine generator. Learn more here.

Bridge Seismic Force Monitoring Solution

A customer wanted to monitor seismic activity that occurs to a bridge using force sensors to continuously monitor activity before, during and after earthquakes. They also wanted a wireless solution to avoid running long cables on the bridge. Interface provided an LP Load Pin custom made to fit the need. The load pin was used in conjunction with our WTS Wireless Telemetry System to monitor the force on the load without cables. Using this solution, the customer was able to monitor continuously, log results to the cloud and review the data. Read more here.

Driving Force in Automotive Applications

Among the most highly regulated industries in the world, automotive is up there with the likes of medical and defense. Every component and system needs to be thoroughly tested and deliberately analyzed to ensure that the final product is safe for the driver, other vehicles and pedestrians. Any mistakes or failures can cause catastrophic damage and put lives at risk.

There are hundreds of thousands of different tests that car parts and software go through before they are approved for the road. Among them is force measurement testing. Force and torque tests are integral to the structural and mechanical design and build of the car. Gathering data on the build quality and safety of materials and components found within cars, trucks and more is done through a wide variety of different force measurement testing.

Interface has been a partner to the automotive industry for more than 50 years, from the major OEMs to smaller parts manufacturers and test labs. We build force and torque sensors and acquisition devices designed to provide automotive engineers and manufacturers with high-quality data to monitor and confirm the design and in-action processes of a wide variety of vehicles.

Force testing applications for the automotive industry involve everything from structural, engine, brake, seat belt and suspension tests, all the way down to individual lug nut torque testing.

Recently, Interface has also been supplying solutions to those in the growing electrical vehicle (EV) market. EV cars and other motor vehicles present a wide variety of unique challenges for engine torque and battery technology testing.

As an example of some of the products we offer to the industry, we are highlighting Interface expertise in different automotive applications. This will include specific examples of work we’ve done for our customers recently or in the past.

BRAKE PEDAL TESTING

One of the largest areas of automotive test and measurement we are involved in is brake pedal testing. Our customers need to ensure that applying certain amounts of force to the brake will slow and stop the vehicle as intended.

In this application note, Interface supplied our customer with a BPL-300-C Brake Pedal Load Cell, which was installed on the brake pedal. As the user depressed the brake pedal, force data was transmitted by our BTS-AM-1 Bluetooth Low Energy (BLE) Strain Bridge Transmitter Module to the BTS Toolkit Mobile App and displayed on a mobile device. This allowed our customer to view and graph the data in real-time.

EV BATTERY TESTING

In the EV market, one of the most integral pieces of technology is the battery used to run every piece of hardware and software in the car. One of the critical tests that’s performed on EV batteries in compression testing. As an EV battery is charged and stores more electrons, it swells. If the packaging that houses the batteries is not intelligently designed to compensate for this swelling, you could have a major problem.

For this challenge, Interface can supply the popular WMC Miniature Load Cell. The load cell will measure compression force as a battery goes through charge cycles on a test stand to determine the force given off as the battery swells. This allows our customers to design the proper packaging for the batteries.

SUSPENSION TESTING

A personal favorite of the Interface team is a suspension test we performed on a race car. As you can imagine, race car components need to be finely tuned for optimal performance. The suspension is one of the most significant factors in the tuning process.

Using an Interface Model 1200 Standard Load Cell, we were able to measure simulated motions of a racetrack including bumps, banks and other track conditions. This allowed the customer to gather highly accurate (0.04%) measurements of loads applied to individual suspension points. This type of suspension testing technology can also be performed on a regular commercial automobile, but the race car example is much more fun!

MOTOR TESTING

In this motor test stand application, it was used in the quality control lab of a major automotive manufacturing customer that needed to test, record and audit the torque produced by a new motor design under start load.

Interface supplied a Model AxialTQ Rotary Torque Transducer that connected between the motor and the differential, on the drive shaft, which could measure and record these torque values. Based on the data collected using the AxialTQ, AxialTQ Output Module, and customer laptop, the test engineer was able to make recommendations to optimize the amount of torque created by the new motor design.

You can read more about the AxialTQ in this post.  

The wide variety of applications for automotive force testing that Interface has been involved in is significant. We have many published application notes beyond those highlighted, including Seat Testing, Engine Head Bolt Tightening and one for an Engine Dynamometer (dyno for short) use case. The examples listed above just scratch the surface.
