Elasticity 101

Elasticity 101

Interface's Elasticity 101 details the importance of Hooke's Law of Physics. In a load cell, we want a material with a very predictable stiffness. If the material permanently deforms or creeps, the deformation value won't return to zero, and your measurements will be inaccurate. A load cell is essentially a mechanical transducer that converts mechanical force into elastic potential energy, which we then capture as data. Understanding how your sensor bends is the first step toward mastering precision force measurement. Learn more in Interface's ForceEDU 101 Series.
Hysteresis 101

Hysteresis 101

Interface defines hysteresis as the algebraic difference between the load cell's output at a specific load when approached from an increasing direction versus a decreasing direction. Hysteresis represents a physical limit of the sensor's design. Hysteresis is typically expressed as a percentage of Full Scale (%FS) on a sensor's data sheet or calibration certificate. Learn more about this vital characteristic in Interface's Hysteresis 101.
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.
