Can Load Cells Be Repaired?

/0 Comments/in /by

Load cells are very resilient. Most are constructed with sturdy materials that can withstand long and arduous cycling and multitudes of testing projects. In fact, with proper treatment, regular calibration services and use within specifications, load cells can last many years. Even with such high quality and durability, it is important to perform regular diagnostic checks of a load cell to maintain the health of any force measurement device.

FACT: Interface has load cells that are in use today that we manufactured several decades ago. As the saying goes, Interface load cells are built to last.

A load cell can be damaged or lose accuracy. Load cells can be repaired depending on the extent of damage. Some common issues such as cable damage, electrical faults, or environmental factors can be repaired by replacing parts or recalibrating the load cell. However, more severe damage such as physical damage to the load cell itself may make it beyond repair and require replacement.

What is the most common type of damage to a load cell?

Most often, a load cell is damaged by overloading or exceeding its rated capacity. This can result in physical deformation or strain on the load cell, leading to permanent damage and reduced accuracy.

Other common causes of damage to load cells include exposure to harsh environmental conditions such as extreme temperatures, moisture, or corrosive substances, as well as electrical faults such as voltage spikes or short circuits. Additionally, mechanical stress from improper installation or handling can also cause damage to load cells.

What steps should be taken to evaluate a load cell that might be damaged?

  • Visual Inspection: Ensure that the physical installation, correct interconnection of components and the system are all intact. For example, has the load cell been dropped or have any damage to connectors or adapters? Reference the installation and operation manuals available with each product.
  • Electrical Testing: Use an Ohmmeter to check the bridge circuitry and zero balance. Evaluate the resistance and output of the load cell. If there is a notable change in resistance or output, it may indicate that the load cell is damaged. This is also a good time to check the troubleshooting guide.
  • Test Loads: Apply a range of test loads to the load cell and observe if the readings are consistent and within the expected range.
  • Calibration: If the load cell is not functioning correctly, recalibrate it using a weight calibration system or load cell calibrator to see if the readings are within the expected range.
  • Professional Evaluation: Request a thorough inspection of the device to determine the load cell can be repaired or needs to be replaced.

It is important to follow safety protocols and to use proper equipment and techniques when evaluating a load cell to avoid causing additional damage.

After a thorough physical inspection along with mechanical and electrical installation checks, it is determined that a load cell is not performing to specifications it is time to contact the manufacturer for Services & Repair to schedule a return of the product for further evaluation and potential load cell repair.

Use Cases for Frequent Calibration Services and Repair Evaluations

  • Harsh environmental conditions can cause corrosion and electrical failures
  • Loading forces that exceed the load cell rated capacity can cause shifting of the zero-load output of the load cell
  • Moment loading of the load cell can cause zero shifts and other undesirable behavior
  • High cycle rates or fatigue applications can cause premature failure

Many of these symptoms can be repaired or mitigated if they are identified early during appropriate evaluation and calibration cycles. In addition, load cells are prone to losing accuracy through normal wear and tear and ageing. There are times when loading conditions and use case environments necessitate the need for more frequent evaluation and calibration cycles. The process of calibration can include adjusting the measuring instrument to bring it in alignment with the standard specifications.

It is always recommended that users consult an application engineer or user’s manual to avoid situations where a load cell can be damaged or degrade accuracy too quickly. Interface has deeps expertise in repair and calibration, built and proven over 55 years in the business of making and calibrating load cells.

Interface provides repair evaluation and services on load cells we make and from other manufacturers. Repairs include a complete evaluation of the device prior to repair and calibration upon completion. Our standards for calibration are world-class. Our calibration labs are managed by experts in diagnostics, testing and repair with engineering and metrology grade equipment designed by the leaders in force measurement.

If you’re already a load cell user and have not had your products calibrated in some time, we recommend scheduling your calibration service online here. Load cells can provide years and years of quality data as long as they are properly taken care of. Put your trust In Interface to make that happen.

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

 

 

 

 

 

An 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. Read more.

Bicycle Load Testing

A mountain bike manufacturing company wanted a system that measures their bike frames load capacities and vibrations on the frame.

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.

/0 Comments/in /by

Interface has been a long-term supplier of force and torque measurement solutions for the maritime industry. Learn how our products play a big role in a wide variety of test and measurement applications for waterborne vessels, maintenance and safety equipment. Our load cells and instrumentation are found in offshore products, as well as at docks and in the open water. We have captured some of these specific use cases of how our sensor technologies and instrumentation are used in the building and maintenance of boats, yachts, and watercraft of all sizes.

Our load cells and sensors work well in vehicles that are used in water. For example, we offer technologies that can wirelessly transmit data underwater and in harsh weather conditions, making them perfect for a variety machines used in water. These specialized load cells operate in underwater submersions at different capacities, and reliably relay information to those at the surface level for accurate sensor readings. Interface load cells of various designs can regulate harsh maritime situations in use cases such as underwater tension lines, underwater oil drilling, as well as storm and tsunami monitoring. Read more about offshore and near shore solutions here.

The applications we are highlighting below provide real-world examples of force measurement products used in boat, yacht and watercraft related products. The uses of force measurement range from testing fishing wire to yacht rigging inspection. Here’s a closer look:

Wireless Telemetry System (WTS) for Yacht Rigging Inspection

For a customer who wants to have a complete yacht rigging inspection to make sure the mast, still lines, and all movable hoisting lines are functional, Interface offers our robust WTS product line. These various wireless sensor technologies and components are designed for use to meet the proper specifications for sailing, testing the tension of the forestay, shroud, and backstay cables, and to test the tension of the movable lines when sailing.

With Interface’s WTSSHK-B Wireless Crosby™ Bow Load Shackle paired with the WTS-BS-1 Wireless Handheld Display for Unlimited Transmitters, the customer can switch and view between multiple shackles being tested. The WTS-BS-4 USB Industrial Base Station can also be attached to the customer’s computer to display real-time measurements from the shackles and log data. With this solution, the user is able to conduct both running and standing rigging inspections of their ship or vessel, and determine if all lines were functional and met safety standards.

Commercial Fishing Wire Rope Testing

When a commercial fishing owner wanted to measure the force tension of the wire fishing rope connected to the fishing cage or net when their vessel goes to catch and ensure the wire rope is strong enough and safe enough to hold the maximum capacity of fish caught in the cage or net, they can turn to Interface.

Using a WTSTL Wireless Tension Link Load Cell attached between the end of the cable, and the end that hooks onto the fishing net, the tension link will be able to measure the forces of the full net of fish, or a heavy load at maximum capacities. The data information can be transmitted to both the WTS-BS-1-HS Handheld Display for Single Transmitters, or to the customer’s computer using the WTS-BS-4 USB Industrial Base Station. Utilizing this solution, the customer was able to determine if the fishing cable on their vessel was strong enough to hold the fish cage or net at maximum capacity when out catching.

Mooring Line Tension Testing

Due to changing environmental conditions, mooring cable lines undergo wear and tear. A customer wanted to ensure all mooring lines for ships and large commercial vessels are securely docked at the same loading tension, so that they do not risk the mooring lines to break or cause damage.

We provided a WTSTL Lightweight Wireless Tension Link, which can be 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-HA Handheld Display for Multiple Transmitters, giving the customer the option to view multiple mooring cable line tensions. The customer was able to verify the tensions to multiple mooring cable lines. Thus, resulting in the security of their ship being safely docked.

Interface Crane Use Cases and Application Notes

/0 Comments/in /by

Manufacturers and engineers of heavy equipment are rigorous about the design quality, performance and most importantly preserving safety. Having tools to test and monitor this type of equipment allows equipment producers and users to review performance at all stages, ultimately maintaining a safe working environment which is critical to any construction, transportation, or infrastructure project job site. That’s why Interface provides quality force measurement products for a host of industrial equipment machines to accurately measure force, load capacity, weight, tension and more.

Interface has been a long-time supplier of force and torque sensors along with instrumentation products for projects involving all types of cranes and lifting machines. We are frequently asked to provide crane force measurement solutions for applications used in hoisting, lifting, moving, and transporting heavy objects. These use cases range across all types of environments, from constructing high rises in metropolitan centers around the world to maritime industry users loading docks and lifting watercraft.

To outline how force measurement is used to monitor cranes, we developed a series of application notes explaining the components Interface provided to allow our customer to measure safety, reliability, and efficiency of their equipment.

Crane Capacity Verification

The first application note outlines a project in which the customer wanted to verify that their crane was strong enough to safely lift a heavy load at its rated maximum load capacity. It was determined that because of the size of the crane, a wireless solution was needed to avoid long wires and burdensome installation. Interface provided a WTSTL Lightweight Wireless Tension Link Load Cell to measure the load’s maximum capacity. WTS-RM1 Wireless Relay Output Receiver Modules were also used to trigger an alarm that can be set when the maximum capacity of weight/force has been reached. To review the data the customer could transmit the data to a PC or laptop with a WTS-BS-4 USB base station. The data can also be reviewed through a WTS-BS-1-HS Wireless Handheld Display. With this solution, the customer was able to verify if the crane is safe and functional enough to lift it’s working load limit (WLL), or safe working load (SWL) capacity.

Crane Block Safety Check

The next example features a crane application in which the customer wanted to detect whether a crane block could lift a heavy load securely to keep working conditions safe for personnel. The customer specifically wanted the solution to include an alarm feature that notified them if lifting capacity was exceeded in real-time. Using a WTSLP Wireless Stainless Steel Load Pin in place of a load bearing pin in the crane block, they could measure the force being applied by the heavy load. Data will be transmitted and displayed through both the WTS-BS-4 USB Base Station. It can also be paired with the WTS-BS-1-HA Wireless Handheld for real-time safety monitoring. The WTS-RM1 Wireless Relay Output Receiver Module triggers an alarm when maximum capacity has been reached. The customer was able to verify if the crane was operating safely and was always functional enough to lift it’s working load limit (WLL) or safe working load (SWL) capacity. The added alarm feature is critical for notifying users when the crane reaches unsafe limits during operations.

Crane Force Regulation 

In the final application note, a customer wanted to regulate the maximum number of heavy loads being lifted, so that production time was both safe for workers and efficient. The goal was to complete lifting duties faster and with little or no expense. A wireless solution was also preferred, so that there would be no long cable interference during production. Interface supplied a WTSLP Wireless Stainless Steel Load Pin, which can be custom made to be used for any and all types of cranes. It is also great for lifting both short and long distances. The load pin was paired with the WTS Wireless Telemetry System, where force could be measured and logged. The customer was able to monitor the continuous force from the crane, and gather information on loads being lifted for continuous safety and production reporting requirements.
