Load Cell Design Faqs

Load Cell Design FAQs and Engineering Tips

Interface engineers provide tips and insights on load cell design, installation, calibration frequency, and common failure modes. A reliable quality load cell must be designed with appropriate materials, installed correctly, and regularly maintained to ensure accurate output. Understanding a load cell's fundamental performance characteristics is a strategic necessity. Maintaining the sensor and preventing overload are essential for achieving high-accuracy measurements.
Seven Terms

Seven Essential Terms in Force and Torque Measurement

Force and torque measurement rely on precise technical vocabulary. Load cell terms like side load, moment, and ultimate overload determine a sensor's accuracy, lifespan, and safety. Understanding seven terms can prevent failure, loss of testing data or protect the investments in measurement systems.
CONTACT RESONANCE 101

Contact Resonance 101

Contact resonance can significantly damage measurement accuracy and even cause system failure. Interface 101 Series details how inherent mechanical clearances within the measurement system can turn harmless transient forces into potentially destructive oscillations. Contact resonance is a form of self-excited oscillation that occurs in mechanical systems involving mass, stiffness, and a clearance. Interface Load Cells 301 Characteristics and Applications Guide covers this important topic.
NONLINEARITY 101

Nonlinearity 101

Nonlinearity refers to the deviation from a straight line during a single, continuous loading cycle, which is a percentage of full scale from zero to full load. Interface 101 Nonlinearity details this crucial specification because it directly impacts the accuracy of your measurements. A load cell with a high nonlinearity percentage will give you inaccurate readings, especially at the intermediate points of its measurement range.
Force Stress And Strain Measurement

Core Measurement Fundamentals of Force, Stress, and Strain

Understanding differences in measuring force, stress, and strain, and how Interface's load cells accurately measure changes in objects, will help you better prepare to maximize the potential of your force measurement solutions for critical applications.
INTERFACE TECH TALK Resistance Output Vs Rated Output

Resistance Output Versus Rated Output

Rated Output (RO) is the dynamic electrical signal that directly represents the applied mechanical force. Resistance Output is a static electrical characteristic of the load cell's internal circuitry. When you are performing force measurements, you are primarily interested in the Rated Output. This value, in conjunction with your excitation voltage, enables you to accurately convert the measured millivolt signal into engineering units of force in lbf or Newtons.
