INTERFACE TECH TALK Torque Wrenches

Why Do Torque Wrenches Use Transducers?

Interface's Tech Talk reviews torque wrenches, applications, and FAQs when combining wrenches with reaction torque transducers to validate the tightness of fasteners, bolts, screws, and other mechanical assembly tools used in aerospace, energy, automotive, and manufacturing. A torque wrench is only as reliable as the data supporting it. Combining a torque wrench with high-accuracy torque measurements from torque transducers and advanced instrumentation provides the validation necessary to protect machines, equipment, products, consumers, and workers.

Fatigue Life Prediction

Fundamentals of Fatigue Life Prediction

Interface load cells accurately quantify the forces applied during fatigue testing for predicting failure. Fatigue refers to the weakening of material caused by repeatedly applied loads. Failure occurs after a certain number of cycles, even when the stresses are well below the material's ultimate tensile strength. While an accurate prediction of fatigue life is not a reality, theoretical analysis and empirical data allow for useful approximations to estimate the margin of safety for a given design.
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.
INTERFACE TECH TALK Adv Compression Only

Unidirectional Advantage of Compression-Only Load Cells

Interface compression-only load cells are utilized in test and measurement applications for enhanced performance, quality, and reliability in single-axis compression scenarios. The deformation of the strain gage provides measurement data. The design offers a more stable output and a higher resistance to off-axis loading, which can significantly reduce measurement uncertainty. Interface Tech Talk answers the unidirectional advantages of using compression-only load cells.

Moment Compensation 3

Moment Compensation Relevance for Aerospace, Robotics, and Structural Testing

Moment compensation is a fundamental engineering principle that ensures stability and accuracy by counteracting unwanted forces. Industries like aerospace, robotics, material and structural testing know precision is non-negotiable. At Interface, the moment compensation principle is a core part of our load cell design best practices, making our force measurement solutions a decisive component in some of the world's most demanding 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.
