/0 Comments/in /by

A load pin, which often replaces a standard clevis or pivot pin, is a strain gage sensor that measures the force applied across the device. The strain gages are installed within a small bore through the center of the pin. Interface load pins have been used in a wide variety of projects across industries.

Load pins are a simple, but highly powerful sensor that provides data collection for accurate and frequent measurement. The load pin can replace a bolt, clevis, sheave, and an equalizer pin, as well as other load-bearing components to measure tensile and compression forces.

Machined from high tensile stainless steel, Interface load pins are suitable for exposed situations including seawater. We offer standard sizes of load pins between 1.1K lbf to 3.3M lbf (500kgs to 1500 MT). We also have wireless load pins. Interface load pins are custom manufactured to meet specific dimensional requirements for each application, as detailed in our Use Cases for Load Pins webinar.

The most commonly referenced applications for load pins are for overhead equipment like cranes and lifts. Through ingenuity of engineers and our customers, load pins are rapidly expanding in popularity for infrastructure, aerospace, maritime, agriculture, and industrial use cases. The load pins of today are used to test and measure force, load and weight in a much larger variety of applications. They are also growing in demands due to their wireless capabilities for both short and long distances. This includes uses not only for cranes and lifting devices, as well as construction equipment, industrial machines, nautical craft and equipment, aerospace structural environments, and civil engineering applications.

Infrastructure investment and projects around the world are on the rise. Investments in transportation ways like highways, waterways, bridges, mass transit, water supplies and power generation are frequently in demand of load pin solutions for use in all phases of the projects, from construction to maintenance and real-time monitoring.  Some of these examples are highlighted in Infrastructure Projects Rely on Interface.

Interface has a great deal of experience supplying ruggedized and standard use load pins for testing. Our load pins are highly demanded in the infrastructure industry not only due to the accuracy and reliability of our sensors, but also due to the fact that we offer a myriad of communication channels to offer both wired and wireless solutions. As requirements are made to repair and rebuild public infrastructure resilience, equity, and safety for all users are key criteria in design and build stages.  This is where Interface load pins are key to the solution, for durability, accuracy, quality, and ease-of-use.

Interface captured a few application examples of how our load pins are used for different types of projects, from maritime submersibles to monitoring new bridges during earth’s constant shifting.

AEROPSPACE:  Landing Gear Joint Testing

A global manufacturer in aerospace needs to test their new assembly and design by testing its landing gear joints. They want to ensure there are no flaws in the gear shock absorber design and can handle the applied forces when the craft lands from a flight. Interface’s WTSLP Wireless Stainless Steel Load Pins can be installed and replace the normal pin joints. The aircraft undergoes multiple drop tests at different heights, where the forces applied on the load pins transmitting the measurement data. The force results are transmitted wirelessly to the WTS-BS-4 USB Industrial Base Station and the WTS-BS-1-HA Handheld Digital Display for multiple transmitters. Read more about this load pin use case here.

MARITIME: Quick Release Hooks (QRH)

A customer wanted to test their quick release hook (QRH) system when their vessels are docked. They wanted to ensure the mooring lines are secured, but also, the quick release hooks were able to be easily and safely released. Interface’s WTSLP Stainless Steel Load Pin was installed into the quick release hook, where forces from the mooring lines can be measured and displayed when paired with the WTS-BS-4 USB Industrial Base Station. The load tension forces were displayed in real-time on the customers PC or laptop. The WTS-RM1 Wireless Relay Output Receiver Module alarm could also be triggered for the customer when maximum safety work load capacities have been reached or are overloaded. Using this solution, the customer was able to determine if their quick release hooks worked effectively within the safe working limit specifications, and was aware of any potential overload situations. Read more here.

INFRASTRUCTURE: Bridge Seismic Force Monitoring

A customer wanted to monitor seismic activity that occurs to a bridge by using force sensors and then continuously monitoring bridge forces before, during and after earthquakes occur. The customer preferred a wireless solution so they would not need to run long cables on the bridge. Interface helped to develop its LP Load Pin, which were custom made to fit their needs along Interface Inc. WTS Wireless Telemetry System continuous force monitoring was able to take place without long cables. Using this solution, the customer was able to monitor continuous loads, log information to the cloud and review information. Read about this solution here.

AGRICULTURE: Tractor Linkage Draft Control

A farming operation needs to measure the forces applied on their tractor’s draft control, between the tractor and any linked on attachments. Measuring the force helps the farmer sense any strains on the hitch of the tractor, and will be needed in order to apply any specific settings to the draft control when the tractor encounters rough terrain.  Interface’s WTSLP Wireless Stainless Steel Load Pin is a wireless load pin that can be installed directly in the hitch, replacing the normal shear pin of the tractor. Force results are transmitted wirelessly to the WTS-BS-4 USB Industrial Base Station, where they can view the results on a computer using Interface’s WTS toolkit. The customer can also view results on the WTS-BS-1-HS Handheld Display for Single Transmitters in real-time. Read more about this IoT Agriculture solution here.

 

INDUSTRIAL AUTOMATION: Crane Block Safety Check

A customer wanted a system to detect if their crane block can lift heavy loads securely, in order to keep working conditions and personnel safe. If lifting capacities are exceeded, the customer wanted a system to alarm them in real-time. Interface’s WTSLP Wireless Stainless Steel Load Pin replaced the existing load bearing pin in the crane block in order to measure the force being applied by the heavy load. The data was transmitted and displayed through both the WTS-BS-4 USB Base Station (when paired with the customer’s supplied PC computer/Laptop) and the WTS-BS-1-HA Wireless Handheld for real-time results. The WTS-RM1 Wireless Relay Output Receiver Module could also trigger an alarm when maximum capacity has been reached. The WTSLP Wireless Stainless Steel Load Pin, combined with the WTS products, was able to measure and determine force applied the moment a heavy load is lifted. The results were transmitted wirelessly, and ensured the customer whether or not the crane block was safely operational during production.

Benefits of Proof Loading Verification

/0 Comments/in /by

Proof loading is a critical test that is performed on sensors or load cells to verify their performance and accuracy under extreme conditions. Engineers may need to request proof loading verification to ensure that the sensors or other measuring devices being used in a particular application are accurate, reliable, and safe for use.

Upon request, Interface provides proof loading at the build phase of engineered-to-order load cells, as well as load pins, load shackles and tension links. By simple definition, proof loading is a safe overload rating for a sensor.

Load proofing is a special test that guarantees the sensor performs at maximum capacity before it’s released to the customer. If a manufacturer does proof loading, it will be documented in the sensors specifications that are shipped with the product. It is commonly requested for sensors that are used in lifting applications.

Additionally, quality engineers and testing professionals may request proof loading as part of quality control or compliance requirements. By ensuring that sensors and load cells are tested and validated before use, companies can ensure that they meet regulatory standards and maintain a high level of quality in their products and services.

The Proof Loading Process

By requesting proof loading, sensor users can verify the accuracy and reliability of sensors and load cells and ensure that they are functioning correctly and within their specified limits. Proof loading can also identify any issues or problems with sensors or load cells before they are put into service, allowing for repairs or replacements to be made if necessary.

Proof loading for sensors is a process of subjecting a sensor to a higher-than-normal load or stress to confirm that it can withstand that load or stress without any permanent damage or deviation from its calibration. The purpose of proof loading is to validate the accuracy and reliability of the sensor under extreme conditions, ensuring that it will perform correctly when it is in service.

During proof loading, the sensor is exposed to a controlled overload, typically between 150% to 200% of its maximum rated capacity. The sensor’s response to the load is monitored, and the output is compared to its expected behavior. If the sensor performs within acceptable limits and returns to its pre-loaded state after the load is removed, it is considered to have passed the proof load test.

When should you request proof loading for a load cell?

Proof loading for a load cell should be requested when there is a need to verify its calibration and ensure its accuracy and reliability under extreme conditions. This is particularly important when the load cell is used in safety-critical applications, such as in crane and hoist systems, industrial weighing and process control systems, and structural testing applications.

Proof loading is commonly used for sensors that are used in safety-critical applications, such as load cells used in cranes and hoists, pressure transducers used in oil and gas pipelines, and temperature sensors used in furnace applications. By performing proof loading tests, manufacturers and end-users can have greater confidence in the performance and reliability of their sensors, which can improve overall safety and efficiency.

In general, there are several situations where it is advisable to request proof loading for a load cell:

  • Before critical applications: In safety-critical applications, such as those involving lifting, handling, and transportation of heavy loads, a proof load test should be performed before the load cell is put into service to ensure that it can handle the required load without any issues.
  • After installation: It is recommended to perform a proof load test on the load cell immediately after installation to ensure that it is functioning correctly and within its specified limits.
  • After repair or maintenance: If the load cell has undergone repair or maintenance, a proof load test can be used to verify that it is still performing accurately and within its specifications.
  • After an extended period of non-use: If the load cell has not been used for an extended period, it may be necessary to perform a proof load test to ensure that it is still functioning correctly.

It is important to note that proof loading should only be performed by qualified and trained personnel using the appropriate equipment and procedures. This will ensure that the load cell is not damaged during the testing process and that it continues to perform accurately and reliably after the test is completed.

Proof loading is particularly important in safety-critical applications such as in the construction industry, transportation industry, and other industrial applications where lifting and handling heavy loads are involved. In these applications, the accuracy and reliability of sensors and load cells are crucial, as any inaccuracies or deviations from the expected behavior can result in dangerous and costly accidents.

Overall, proof loading is an essential test that engineers may need to request to ensure the safety and reliability of sensors and load cells in various industrial applications.

Top Selling Interface Ruggedized Products

These types of products follow strict certification standards and ratings. During the online seminar, Interface product experts detail the standards and ratings related to intrinsically safe products, sometimes referred to as hazardous location use, as well as solutions designed to meet safety, regulatory or compliance requirements.

The standard ensures that an intrinsically safe device is incapable of triggering combustion or igniting any gasses or vapors. The device is safe to use around dust and gas without risking static electricity or heat discharge from the device igniting the surrounding volatile gasses, powders, and liquids.  Explosion proof applies to a device enclosed in a case that can withstand a gas or vapor explosion.  Should there be an explosion, it will be contained within the enclosure.

Interface offers products with different IP ratings, including IP66, IP67 and IP68 applied to different transducers and instrumentation. Ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids ingress protection (IP) ratings, which grade the resistance of an enclosure against the intrusion of dust or liquids.

  • IP65 – Dust-tight, protected against water jets
  • IP66 – Dust-tight, protected against powerful water jets
  • IP67 – Dust-tight, protected against the effects of temporary submersion in water
  • IP68 – Dust-tight, protected against the effects of continuous immersion in water

What is the difference between IP66 and IP68? IP68 enclosures also provide dust-tight performance against solids. However, they are also rated for significantly better defense against water ingress than an IP66 enclosure. An IP68 enclosure can withstand submersion for over 30-minutes at up to a specified water depth.

Interface also has a range of instrumentation products that are NEMA, and IP rated based on the enclosure and housing designs.  These include:

These vehicles go through extensive and rigorous test and measurement programs and processes requiring the reliability and accuracy of Interface made products. Here are a few types of aerospace applications using Interface measurement solution:

Aircraft Wing Fatigue

Before any of the U.S. Navy’s F/A-18 twin-engine supersonic fighter jets can be put into operation, the wings of the aircraft must undergo fatigue testing in a controlled environment to ensure that they are capable of withstanding the forces that will be encountered during real-world flight throughout the lifetime of the aircraft. Highly accurate measurements must be recorded in order to make sure that a near-exact replication of in-flight conditions are being achieved. During fatigue tests, Interface’s 1248 Standard Precision Flange LowProfile Load Cells are installed in line with the hydraulic cylinders, which apply back-and-forth loading forces to the aircraft. This is carried out over the course of 18 months to simulate in-flight stresses and strains on the wings. Load cells are connected to indicators, which record output. Capable of withstanding more than 100 million (1×108) fully reversible load cycles, Interface’s LowProfile Fatigue-Rated Load Cells have performed flawlessly in F/A-18 wing testing with zero recorded failures in the many years that testing facilities around the world have been using them.

Rescue Helicopter Hoist Test

When a customer wanted to test the strength of the cable line used in the hoist of their helicopter during rescue missions and situations, see if both the cable and the hoist can withstand a heavy load safely, and for long periods of time while the helicopter is in flight, they turned to Interface. We supplied a WTSSHK-D Wireless Crosby™ Load Shackle, which is attached to each mooring cable in use. Results are sent to the customers through the WTS-BS-4 USB Industrial Base Station when connected to the customer’s supplied computer. Data can also be transmitted to the WTS-BS-1-HS Handheld Display for Single Transmitters, giving the customer the option to view mooring cable line tension. Using this solution, the customer was able to add a heavy load to the end of the helicopter hoist, to ensure it is strong and safe enough to carry both rescue personnel and objects while being in midair.

The aerospace industry is responsible for some of the greatest inventions and innovation in our global history. The engineering and manufacturing of a single rocket engine design, using handwritten calculations and with less computing power than a modern smartphone, took us to the moon. The aerospace industry is an assembly of researchers, design houses, test labs and manufacturing companies that engineer and build vehicles to travel within and beyond Earth’s atmosphere using Interface products. Whether you need a million-pound jumbo load cell, custom load pin, or wireless instrumentation, we understand aerospace requirements and our engineers are on stand-by to assist.

These load cells can survive through underwater submersions at different capacities, and still be able to relay information to those at the surface level. Interface load cells can also regulate harsh maritime situations such as underwater tension lines, underwater oil drilling, and storm and tsunami monitoring.

Interface wireless load pins, load shackles, and tension links are ideal for sea applications paired with our different wireless sensor transmitters, receivers, and handheld displays. Our Wireless Crosby Bow Load Shackles are used for mooring line tension testing and rigging inspections. Our load shackles are also inter-changeable with our WTSTL Wireless Tension Link Load Cell. The WTS-BS-4 Wireless Industrial USB Base Station is a popular transmitter that gives outstanding coverage and can be easily paired with one of our handheld displays such as the WTS-BS-1-HA Wireless Handheld Display for Multiple Transmitters, or the WTS-BS-1-HS Wireless Handheld for Single Transmitters.
