Announcing the Launch of the Interface Pressure Compensated Downhole Load Cell

Interface is excited to announce the release of a new downhole solution for the energy industry, the Interface Pressure Compensated Downhole Load Cell (IPCD).

The IPCD is a Wheatstone bridge foil-gaged-based force measurement solution using proprietary compensation methods and designed to provide highly accurate force data in harsh environments, like those found in the oil and gas industry, while requiring limited maintenance compared to similar solutions on the market. This is a product line that is many years in the making, as we’ve offered it as a custom solution. In fact, it has been developed across multiple applications to meet the needs of the oil and gas industry.

Interface’s new IPCD product is best suited for tension head applications of wireline services, particularly useful in deviated or horizontal wells where topside measurements are no longer reliable. Many applications include conveyance, pump down, perforating, tractor, and high pressure high temperature deep offshore use.

The key benefit the IPCD provides over existing solutions, commonly referred to as “wet” load cells, is its method of compensation. Wet load cells have a hydraulic compensation mechanism that uses pistons and seals, requiring frequent maintenance. Hydraulic compensation is complex for smaller tool providers and performance was suboptimal. For the IPCD, Interface developed a proprietary technology that compensates for that pressure influence and allows for bridge isolation. This means that the IPCD is far more rugged, needing little to no repairs, and it can be used downhole without risk of damage, a first of its kind in the industry.

It provides accurate measurement of downhole tension conditions in both vertical and horizontal wells and the proprietary internal compensation actively measures only the portion of the load caused by axial force, ignoring the portion of the load caused by pressure. Since it is an inherently passive system with no active pressure measurement being made or using a separate transducer, it is a completely analog solution for reliability and temperature stability.

We also test the IPCD heavily before it leaves our doors. The oil and gas industry can be extremely volatile, so we understand that our load cells need to be at peak performance for every use. Each load cell is tested individually on force, creep, temperature and pressure.

Advantages of the new proprietary Interface Pressure Compensated Downhole Load Cell include:

  • IPCD is a standard product from Interface and available today
  • IPCD offers maintenance-free service with significant long-term payback by eliminating disassembly, downtime, calibration, and instrumentation configuration
  • Interface’s new product is a precision with unmatched performance
  • IPCD has minimal thermal and pressure error, combined with world class linearity and hysteresis
  • It has field proven reliability and was designed based on a decades of engineering and force measurement experience

To learn more about the IPCD, we recently published a white paper that goes deeper into how the unit works, the specifications of the solution, as well as providing additional information on our testing process. You can read more about the IPCD in our new technical overview, Interface Pressure Compensated Downhole Load Cell White Paper available online for download.

We also issued a press release announcing the launch of IPCD.

This new product launch is a collaborative effort involving many of our team members in engineering, production and sales.

 

Interface Solutions for Testing Tools

Interface load cells, torque transducers and instrumentation are commonly used in the test and measurement of different tools and fasteners used in testing products and actual production of various machines and components. The sensor data received in measuring assembly tools and fixtures used in securing nuts, bolts, and screws, is critical in making safe and reliable products.

For example, the ability to measure torque on screws and the force output of a screwdriver or wrench is very important when there are tight tolerances involved like in engineering and build of automotive or aerospace and defense machines and parts.

As we did for the machine testing blog, we’ve detailed a few examples of how Interface force and torque solutions are used in measuring tools performance for both design and assembly.  You can find additional application notes on these examples and more by visiting our industry solutions.

Bolt Fastening Force and Torque

An aerospace company was working on a test plan that involved taking torque and compression measurements on fasteners with varying joint materials. The system required both high and low sampling rates, in addition to the capability of precisely measuring force and torque simultaneously. They required reliable accuracy and long-term stability. The test plan intended to provide verification of required force and torque specifications for fasteners, to ensure safety without compromising installation. Interface suggested a LW or LWCF Load Washer in conjunction with a  T12 Square Drive Rotary Torque Transducer. With this solution, the customer was able to align force and torque measurements to desired levels. This was accomplished by combining the sensors with the high sample rate of the data logging and graphing capabilities of the SI-USB, capturing real-time force and torque levels for examination. The fasteners were tightened to the specified force and torque requirements and were safely installed without impairment to themselves or the joint material. The customer was able to measure the rapid event effectively and accurately. Read more about this bolt fastening solution here.

Aircraft Screwdriver Fastening Control

An airplane manufacturer needed a solution where they can control the torque when fastening screws on their airplane models. They didn’t want to create any damage to materials or apply too much torque when plane components are being fastened together. Interface suggested a T15 Hex Drive Rotary Torque Transducer, which can be attached to the fastening work bench, measuring and recording torque, rotational speed, and angle of the screwdriver. The LWCF Clamping Force Load Cell is installed, measuring the forces applied on the screw being fastened. Results are sent to the SI-USB4 4-channel USB Interface Module, which is connected to the customer’s PC or laptop where data is logged, graphed, and displayed. This solution allowed the airplane manufacturer to calibrate their screwdriver by measuring its torque, rotational speed, and angle, when attaching materials together for their airplane. They were also able to measure the forces being applied to the screw, to ensure it was not applying too much torque to the components. You can learn more about the aircraft screwdriver application here.

Ratchet Wrench Torque Verification

A customer wanted to perform regular torque testing on his ratchet-type torque wrench while recording these values for future examination. Interface supplied a model TS15 Square to Flange Reaction Torque Transducer with the INF-USB3 PC Interface Module for the customer to use. The customer mounted TS15 to work bench through flange and inserted the ratchet-type torque transducer into the TS15. Using this product, the customer was able to accurately perform their calibration checks and view the results while logging them to their PC Computer.  Learn more about this wrench torque verification testing here.

While not nearly as complex as machine testing applications, tools testing is equally important to the outcome of a project. The tools and fasteners used, even those as simple as a bolt and wrench, need to be accurately measured and assembled to avoid loose connection or overtightening that can damage the product. Interface provides a host of tool testing solutions for nearly anything that outputs force or torque. To learn more about our tool testing solutions, visit us at www.interfaceforce.com.

Interface’s Steering Role in All Types of Transportation

Interface serves a wide variety of industries that design and manufacture movers of people and objects. The transportation sector consists of companies that assist in the movement people or goods, as well as supporting infrastructure. Whether it is automobiles or planes, trains or helicopters, spacecraft or water vessels, Interface provides solutions to help test and measure force, weight, torque, lift and more.

The safety, quality and reliability of the overall transportation industry are all important considerations in design, build and performance. Human safety being the most critical requirement of any transport vehicle or structure.

This means that stringent testing is necessary to confirm the design of every part and system on a vehicle. Force measurement sensors can used to test a wide variety of factors on every type of invention that moves or transports a person or thing. From the torque of an electrical vehicle engine to the weight distribution of an aircraft, these types of tests help to refine the designs of components, vessels, and vehicles, confirming safety and dependability.

All Interface product categories have a role in the testing of all these transportation entities.  Many of our sensor technologies are also ideal for performance monitoring and integration into product designs, whether it’s for ongoing measurement of weighing ship cargo with load pins, load shackles and tension links or using our torque transducers for engine testing on e-bikes, automobiles, trucks, buses, and other transport vehicles.  If it moves, it needs to be measured. Our force and torque solutions are ideal for every segment of this market sector.

Let’s take a quick tour of a few application examples that demonstrate the different products we provide that are helping get people and objects safely moving down the road, on the rails, in the air and even into space.

Wind Tunnel Testing

A major aerospace company was developing a new airplane and needed to test their scaled model for aerodynamics in a wind tunnel, by measuring loads created by lift and drag. Interface offered a Model 6A154 6-Axis Load Cell which was mounted in the floor of the wind tunnel and connected to the scaled model by a stalk. A Model BX8-AS was then connected to the sensor to collect data. The wind tunnel blew air over the scaled model creating lift and drag, which was measured and compared to the theoretical airplane models. Software in the PC converted raw data signals to actual force and torque values at the stalk. Using this solution, the company was able to analyze the collect data and made the necessary adjustments in their design to improve the aerodynamics of their theoretical airplane models. Read more.

Garbage Truck On-Board Weighing

A garbage disposal company wanted to test the load capacity of their garbage truck bins so they know when it reached maximum capacity. Interface’s solution was to customize and install 4 SSB Sealed Beam Load Cells under the garbage box body, on either side. When trash continues to be piled inside the box body, it will push more force down onto the SSB Sealed Beam Load Cells. When maximum load capacity has been reached, the results can be reviewed and displayed when connected to the 482 Battery Powered Bidirectional Weight Indicator in real time. With this system, the customer was able to test the maximum load capacity of the garbage bin attached to the truck, so they know when to empty the truck’s garbage at the transfer station. Read more.

Engine Head Bolt Tightening

Enging Bolt TighteningAn industrial automation company was building an automated assembly machine for an auto manufactur­ing plant. They needed to tighten all head bolts on an engine on their assembly line to a specific torque value. Having the head bolts precisely and consistently tightened to the engine block is critical to the operation of the engine. Several Interface Model T33 Spindle Torque Transducers were installed in their new machine to control torque, angle, and ensure the head bolt was properly tight­ened. The square drive of the T33 allowed the customer to fix their tool directly to the end of the torque sensor, streamlining the installation. When the machine comes down and screws on the engine head bolts the torque and angle profile are sent to the customer’s machine controller. Based on the feedback received by the machine controller, the automation will pass the engine to the next step in the assembly line or fail and have the engine evaluated further. This allowed the customer to ensure the head bolts were correctly installed according to manufacturer specifications, producing an engine that meets performance and reliability expectations of the auto manufacturing plant.

Bicycle Load Testing

A mountain bike manufacturing company wanted a system that measures their bike frames load capacities and vibrations on the frame. They also want to ensure the bike’s high quality and frame load durability during this final step of the product testing process. Interface suggested installing Model SSMF Fatigue Rated S-Type Load Cell, connected to the WTS-AM-1E Wireless Strain Bridge, between the mountain bike’s seat and the bike frame. This will measure the vibrations and load forces applied onto the bike frame. When a heavy load is added to the seat, the SSMF Fatigue Rated S-Type Load Cell measures the vibrations and load forces applied to the bike to indicate any stress points through a number of cycles. The results will be captured by the WTS-AM-1E and transmitted to the customer’s PC using the WTS-BS-6 Wireless Telemetry Dongle Base Station. This solution helped the mountain bike manufacturing company gather highly accurate data to determine that their bikes met performance standards through this final testing cycle. Read more.

These are just a brief example of the work we do in transportation. Interface systems have been involved in projects with boats, races cars, construction vehicles and even rocket ships. Manufacturers turn to Interface because of our track record for accuracy and the transportation industry relies on this data to keep its customers safe.

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.

Load Washers 101

Load washer load cells are a versatile product used throughout a wide range of industries and applications. These force measurement donut-styled components are frequently used to measure and monitor clamping forces, fastening control, bolt loading and other compressive loads.

A load washer looks remarkably similar to the washers used to distribute the load of a threaded fastener like a screw. A load washer also works in a similar fashion, however they’re made of rugged stainless steel material and use proprietary measurement technologies, like strain gages, which allow it to measure press and compression force rather than just distributing the load.

Interface offers eight different models of load washers of varying sizes and force measuring ranges, all the way from 11.2 to 1124K lbf. The Interface Load Cell Load Washers can be easily designed into products to continuously measure and monitor compression forces. The variety of load washer styles and capacities, all using the thru-hole feature, give product engineers and designers multiple choices for what best fits their application and use case. Specifications for each model are available, along with design files and model ranges online.

For instance, our LWPF1 Load Washer Load Cell is designed to measure press force and is rated at capacities from 450 to 22.5K lbf. It offers a large thru-hole and short height for tight spaces.

Another popular Interface load washer is the LWCF Load Washer Load Cell which can be used to measure clamping forces and also bolt tightening. It has a capacity range of 3.4K to 337.2K lbf and is ideal for determining bolt preloads. We offer precision, high-capacity, and environmentally safe load cell load washers.

Interface also offers two models that have pre-manufactured mounting holes for installation, which are ideal for press force control and measurement. You can see our entire line of load washer load cells here.

Interface load washers are smaller in size, allowing for standard and customized sensors of this type to be used by original equipment manufacturers. We commonly get requests for these load cells for use in industrial automation equipment, medical device testing, test and measurement projects as well as products that need a small but precise sensor.

We’ve also included real-world applications of load washer load cells below. This will give you an idea of the types of projects in which this force device can be used to determine accurate force data used to refine or confirm the design of product or tool.

AIRCRAFT SCREWDRIVER FASTENING CONTROL

An airplane manufacturer was able to calibrate their screwdriver by measuring its torque, rotational speed, and angle, when attaching materials together for their airplane. They were also able to measure the forces being applied to the screw, to ensure it was not applying too much torque to the components. With a T15 Hex Drive Rotary Torque Transducer attached to the fastening work bench, the system measured and recorded torque, rotational speed, and angle of the screwdriver. The LWCF Clamping Force Load Washer  is installed, measuring the forces applied on the screw being fastened. Results are sent to the SI-USB4 4-channel USB Interface Module, which is connected to a laptop where data is logged, graphed, and displayed for test results.  This configuration provided data to calibrate their screwdriver by measuring its torque, rotational speed, and angle, when attaching materials together for their airplane. They were also able to measure the forces being applied to the screw, to ensure it was not applying too much torque to the components.

BOLT FASTENING FORCE AND TORQUE

Using a General Purpose Load Washer Load Cell Model LW in conjunction with a Model T12 Square Drive Rotary Torque Transducer, the customer was able to align force and torque measurements to desired levels. This was accomplished by combining the sensors with the high sample rate of the data logging and graphing capabilities of the SI-USB, capturing real-time force and torque levels for examination. The fasteners were tightened to the specified force and torque requirements and were safely installed without impairment to themselves or the joint material. The customer was able to measure the rapid event effectively and accurately.

Load Pins 101

A load pin is a type of load cell that can replace bolts, clevis, sheave, and equalizer pins, as well as other load-bearing components to measure tensile and compression forces. Load pins are internally gauged with a bored center containing strain gauges, allowing them to convert force into an electrical signal for engineers to accurately collect data.

Most applications for load pins in the past have been for overhead equipment like cranes and lifts. Load pins have expanded in popularity and are now often used to test and measure force, load, and limitations in a much larger variety of applications. This includes uses not only for cranes and lifting devices, but also construction equipment, industrial machines, nautical craft and equipment, aerospace, and civil engineering applications. A primary system approach with structural applications is for safety and to prevent excesses in loading and lifting.

New model types with wireless and Bluetooth technology are also resulting in more use cases for these specialized force measurement solutions. This applies to both test and measurement as well as for installed OEM components within a larger structure or apparatus.

Load Pin Application

One of the largest scale applications of load pins we provided were used to measure force on a large bridge infrastructure project in the western U.S. The goal was to continuously monitor the standard force created by regular traffic, as well as the seismic force before, during, and after earthquakes. The monitoring sensors needed to be integrated into a dampener that would be attached to the structural tower.

The solution allows the company to monitor force from emitted data to cross-reference the standard traffic force with the seismic force to understand its effect on the bridge. Its purpose is to help with predictive maintenance and influence future bridge designs to better compensate for the forces of an earthquake or other natural disasters, which are common in this part of the world.

READ THE SEISMIC BRIDGE MONITORING APPLICATION NOTE HERE

READ THE INFRASTRUCTURE CASE STUDY HERE

The project required a custom product that could handle the inimitable and considerable force of a bridge under every scenario of distress. Engineers developed a custom load pin to handle the force of movement in the bridge in the event of an earthquake. This load pin was much larger than our standard version and is rated at 900,000 lbf. The large load pins were designed to be integrated into the dampener with wireless data acquisition modules connected to the load pins to allow for remote access to the data. With the integration of Interface’s custom load pins and data acquisition module, the customer was always able to continuously collect data for real-time evaluation. The sturdy construction of our load pins and 900,000 lbf rating allowed for readings during all degrees of seismic activity.
