How Load Cells Can Go Bad

/0 Comments/in /by

Load cells are electronic devices that measure the force applied to them. Interface products are made to last, in fact we have many load cells that are in-market and being used for high-accuracy testing that were manufactured decades ago. Why do they last? Quality of design, material construction, build process, calibration, and regular maintenance prolong the life of a load cell.

Like any electronic device, load cells can go bad for a few reasons. It is also important to know that load cells can be repaired. Outside of complete destructive testing, the following issues are most common for how load cell can go bad.

Overloading: Load cells have a maximum capacity, and if they are subjected to a force beyond that limit, they can get damaged. Overloading can cause the load cell to deform or break, resulting in inaccurate readings or complete failure. Preventative options are to use overload protected load cells.

Mechanical and physical damage: Load cells are sensitive devices and can be damaged by impact, vibration, or shock. Mechanical damage can cause the load cell to deform or lose its calibration, resulting in inaccurate readings. Physical damage to devices is often because the load cells are dropped or mishandled during use.

Moisture: Load cells are often used in damp or wet environments, and prolonged exposure to moisture can cause corrosion or damage to the internal circuitry. Environmental exposure to moisture can also cause electrical shorts or create a conductive path between the components, resulting in inaccurate readings or complete failure. Review submersible options if testing in these environments is common.

Temperature: Load cells can be sensitive to temperature changes, and extreme temperatures can cause damage to the internal components. Thermal expansion or contraction can cause mechanical stress, resulting in deformation or damage to the load cell. Interface offers high-temperature and low-temperature load cells options.

Electrical noise: Load cells are susceptible to electrical noise, which can cause interference in the signals and result in inaccurate readings. Electrical noise can be caused by electromagnetic interference (EMI), radio-frequency interference (RFI), or other sources of electrical interference.

Aging: Not all load cells are made the same way. Interface load cells are designed to outlast any testing use for long-periods, we are talking millions of cycles. However, some load cells can wear out over time due to repeated use, exposure to the environment, or other factors. Aging can cause a decrease in sensitivity, accuracy, or stability, resulting in inaccurate readings or complete failure. All load cells need good health checks to stay working at optimal performance.

To avoid load cell failures, it is important to use them within their rated capacity, protect them from mechanical damage, and provide adequate protection from moisture, temperature, and electrical noise. Regular maintenance and calibration services, preferably every year, can also help ensure accurate and reliable performance over time.

What is the best way to determine if a load cell is bad or not working?

There are several ways to determine if a load cell is bad or not working. Here is a reminder of five quick checks:

#1 Visual Inspection: Start by visually inspecting the load cell for any signs of physical damage, such as cracks, deformations, or loose connections. Check for any corrosion or signs of moisture, as well as any visible wear and tear.

#2 Zero Balance Testing: A zero balance test is a quick and straightforward way to check if a load cell is functioning properly. With no weight applied, the load cell should read zero. If it does not, there may be an issue with the load cell or its connections.

#3 Load Testing: Load testing involves applying a known weight to the load cell and checking the reading. If the load cell is accurate, the reading should match the known weight. If there is a significant discrepancy, the load cell may be faulty.

#4 Bridge Resistance Tests: Load cells are typically constructed with a Wheatstone bridge circuit, which can be assessed for proper resistance values. If there is a significant deviation from the expected resistance values, there may be an issue with the load cell or its connections.

#5 Temperature Tests: Load cells can be sensitive to temperature changes, and extreme temperatures can cause damage to the internal components. Evaluating the load cell at different temperatures can help to identify any issues with temperature sensitivity.

Interface provides complete evaluations of any product we manufacture, to determine if the load cell is working properly. To request services, go here.

How does calibration help load cells from going bad?

Calibration is the process of adjusting a load cell to ensure its accuracy and reliability in measuring weight or force. Regular calibration is essential for maintaining the accuracy and reliability of load cells. Interface recommends annual calibration services as a preventative measure and for good maintenance of your force measurement devices.

Calibration helps to ensure that a load cell provides accurate and consistent readings. Over time, load cells can drift from their initial calibration due to environmental factors, wear and tear, and other factors. Regular calibration ensures that any deviations from the standard are detected and corrected, preventing inaccurate readings that can lead to errors in weighing and other measurements.

Load cells that are not calibrated regularly may experience premature wear and tear due to repeated use, leading to damage or failure. Calibration helps to identify any issues early on and prevent further damage, extending the lifespan of the load cell and saving on replacement costs.

Many industries and applications have strict standards and regulations for measuring weight and force. Regular calibration helps to ensure that load cells meet these standards and regulations.

Regular calibration can help load cells from going bad in multiple ways. It can help to prevent inaccurate readings, extend the lifespan of load cells, improve efficiency, and ensure compliance with standards and regulations. Accurate measurements are critical, and calibration helps to ensure that load cells is working properly.

Load Cell Sensitivity 101

/0 Comments/in , /by

Load cell sensitivity refers to the relationship between the input force applied to a load cell and the output signal it generates. It is a measure of the load cell’s responsiveness to changes in the applied force and is expressed in units of mV/V (millivolts per volt) or micro-volts per volt.

When determining the accuracy of a load cell, load cell sensitivity is an important parameter. A higher sensitivity means that even small changes in the applied force will result in a larger change in the output signal, making the load cell more sensitive and accurate.

It is critical to understand that load cell sensitivity and accuracy are closely related. A high sensitivity load cell will generate a larger output signal for the same applied force, which can increase the accuracy of the measurement. In general, the accuracy of a load cell is a combination of its sensitivity and the quality of its design and construction. Interface specializes in precision accuracy, which is important when considering the use case for your load cell.  As defined by the specifications, a high-quality load cell with appropriate sensitivity will provide accurate and consistent measurements, while a load cell with low sensitivity or poor quality may provide less accurate measurements.

Most load cells are designed to measure force in one certain direction, which is determined by the way the load cell is mounted. Inappropriate loading will cause side and eccentric load, which risks reducing the life of load cells and distorting measurement results.

Eccentric load sensitivity is measured by eccentric load, which is any load applied parallel to but not concentric with the primary axis. Side load is any load at the point of axial load application at 90 degrees to the primary axis.

To achieve a desired level of accuracy, it is important to choose a load cell with the appropriate sensitivity for the application. Load cell sensitivity can be affected by factors such as temperature, temperature gradients, and environmental conditions, so it is important to take these factors into account when selecting a load cell.

What conditions impact load cell sensitivity? Load cell sensitivity can be impacted by several factors, including:

  • Temperature: Changes in temperature can cause thermal expansion or contraction of the load cell material, affecting the output signal and reducing accuracy.
  • Temperature gradients: The presence of temperature gradients within the load cell can cause differential expansion or contraction of different parts of the load cell, further affecting the output signal and reducing accuracy.
  • Environmental conditions: Exposure to harsh environments, such as moisture, vibration, and shock, can cause damage or degradation to the load cell, reducing its sensitivity and accuracy.
  • Load cell orientation: The orientation of the load cell can impact the output signal, especially in applications where the load is applied at an angle.
  • Mechanical stresses: The presence of mechanical stresses, such as bending or twisting, can affect the output signal and reduce accuracy.
  • Aging: Over time, the load cell may experience degradation or wear and tear, reducing its sensitivity and accuracy. This is where regular calibration plays a role in the lifetime of your load cell.

It is important to consider these factors when selecting a load cell and to properly maintain and calibrate the load cell to ensure optimal sensitivity and accuracy over time.

Calibration is a process that involves adjusting the output signal of a load cell to ensure that it accurately reflects the applied force. Calibration improves load cell sensitivity by correcting for any errors or inaccuracies in the output signal, ensuring that the load cell provides accurate and consistent readings over time.

During calibration, a series of known loads are applied to the load cell, and the corresponding output signals are measured. These measurements are used to create a calibration curve that represents the relationship between the applied force and the output signal.

Calibration helps to correct for various factors that can affect load cell sensitivity, such as temperature, environmental conditions, and mechanical stresses. By adjusting the output signal to accurately reflect the applied force, calibration helps to ensure that the load cell provides accurate and consistent readings, even in challenging conditions. Interface recommends calibration of every load cell at least once a year for regular sensitivity maintenance.

Interface engineers design high accuracy, quality load cells with appropriate sensitivity that provides accurate and consistent measurements. It is important to consider both sensitivity and accuracy when selecting a load cell for an application and to regularly calibrate the load cell to ensure that it continues to provide accurate and reliable measurements over time.

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.

System Level Calibration Validates Accuracy and Performance

/0 Comments/in /by

Interface strongly recommends when buying any force measurement sensor along with instrumentation that you request a system level calibration. The final step taken to confirm that a sensor and instrumentation are working properly together before leaving Interface is a system level calibration.

System level calibrations provide traceability and record for reference for validating performance and accuracy. It is important to review calibration certificates prior to use and for any troubleshooting. System level calibrations ensure that all system components, including connectors, cables, transducers, and instrumentation are ready to use out of the box.

Interface provides calibration to all individual force measurement components. A basic calibration for the load cell is performed and certified of how the transducer performs in isolation. Expert Interface Calibration Technicians always calibrate these devices to meet the design specification and the exact parameters outlined in the accompanying calibration certifications shipped with the part. A calibration certification characterizes the load cell performance across specific force range with different load points applied output from the load cell versus applied load, confirmed by the specification in voltage outputs, milliamps, or digital output types.

A system level calibration ensures that the performance of the transducer and instrumentation are operating as a system, together. A system level calibration and an associated certification proves the system pairing is functional and essentially plug-and-play ready.

The system level calibration is an important reference for traceability and troubleshooting for the entire system. It can help identify if a setting has been changed or if there is another issue that invalidated the system.

Interface can provide system level calibrations for load cells, torque transducers, multi-axis sensors and other measurement tools that are paired with indicators, amplifiers, USB, and digital instruments. Interface uses a very high quality NIST and NMI traceable mV/V transfer standard to ratiometrically scale or applied force to scale the system. We provide a separate digital indicator calibration certificate indicating how we scaled the instrument.

Interface guarantees our quality performance load cells, torque transducers, multi-axis sensors, and related instrumentation. We certify our products to meet or exceed the quality clauses outlined by the International Organization of Standardization (ISO).

Interface is A2LA Accredited for torque and force calibration in accordance with International Standard ISO/IEC 17025:2017.

From the time we designed our first load cells in 1968, we have been providing calibration solutions. We even calibrate other manufacturers load cells.  Every year, Interface performs more than 100,000 calibrations. Every transducer’s calibration data is stored at Interface, providing a permanent archive.

Even under ideal conditions with normal use, some new load cells can exhibit a slight improvement in accuracy over a period of time. In contrast, load cells are subject to performance degradation due mistreatment, drift, or aging. Throughout the life of a load cell, Interface recommends that regularly scheduled calibration and inspection to monitor performance and minimize uncertainty.

Calibration is a set of operations that compares the accuracy of a measuring instrument of any type, such as a load cell or torque transducer, against a recognized standard. It is often referenced as load cell characterization.

Calibration service ensures the transducer is performing to listed specification. It helps to avoid costly impacts resulting from invalid data or a load cell shutting down a test in progress. Confidence in data is critical in test and measurement. The calibration assures that measurements gathered within the valid calibration period are reliable, trustworthy, and defensible. To maintain  any sensor and minimize cost of poor quality, it is best practice that calibrations are scheduled annually to confirm accuracy to specifications.

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.

Use Cases for Frequent Calibration Services

  • 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

Top Five Reasons Why Calibration Matters

/0 Comments/in /by

Applied metrology is the measurement science developed in relation to manufacturing and other processes, ensuring the suitability of measurement instruments, their calibration, and quality control.

Calibration is the practice of evaluating and adjusting equipment to ensure precision and accuracy. Calibration for force measurement determines whether a sensor is working properly, as well if it needs repair or replacement.

Calibration is critical in the application of test and measurement because it provides controlled methods using equipment and systems that ensure reliability, accuracy, and quality.

We recently shared in our Accurate Report on Calibration seminar, the top five reasons why calibration matters. Below highlights each why.

#1 Reason Why Calibration Matters – Understanding Uncertainty

  • Measurement uncertainty is defined as an estimate of the range of measured values within which the true value lies or, alternatively, the degree of doubt about a measured value.
  • In every application, there will be an uncertainty requirement on the force measurement.
  • The equipment used to make the measurement must be traceable to a realization of the SI Newton unit of force within this required uncertainty.

#2 Reason Why Calibration Matters – Quality and Specifications

  • Calibration ensures the transducer is performing to listed specification.
  • It avoids costly impacts or escapes to manufactured goods and products.
  • Maintaining quality of manufactured device to original specifications is an important reason why calibration matters.
  • It certainly minimizes the cost of poor quality.

#3 Reason Why Calibration Matters – Minimize Downtime

  • Proactive maintenance will always take less time than reactive problem solving and repairs.
  • Identify and repair or replace system components before they fail through regular calibration.
  • Plan calibration intervals to minimize downtime, as a schedule is preventative maintenance.

#4 Reason Why Calibration Matters – Data Accuracy

  • All load cells are subject to potential performance degradation due to mistreatment or drift, impacting data integrity.
  • Pre and post test verification provide assurances in data validity.
  • Confidence in critical measurements is imperative.

#5 Reason Why Calibration Matters – Accreditation and Certifications

  • Calibrations provide adherence to quality management systems and requirements, especially ISO certifications and compliance.
  • It assures that measurements gathered within the valid calibration period are reliable, trustworthy, and defensible.
  • Traceability of measurement is guaranteed with certifications.
