Understanding Dual Shear Load Cells

Interface dual shear load cells are strain gage sensors supported at both ends, with the force applied directly at the center of the beam. A double-ended shear beam load cell design is used in the high-performing Interface LowProfiles and load pins. The dual-ended design distributes force symmetrically across two matched shear webs. Strain gages are bonded to the machined webs inside the beam and configured in a full Wheatstone bridge circuit to convert mechanical shear stress into an electrical mV/V signal.
Moment 101

Moment 101

Interface's 101 Series defines moment as the measure of a force's tendency to cause rotational movement, bending, or tilting when applied at a distance from a fixed point or axis. In force measurement, moment is the physical displacement or rotation that occurs when an unbalanced force acts on an object, and measuring moment in multi-axis sensors provides critical data for a variety of industry applications.

Natural Frequency 101

Natural Frequency 101

Interface Natural Frequency 101 defines the inherent rate at which a sensor oscillates when allowed to vibrate freely. Learn how natural frequency and deflection affect dynamic force measurement, how to avoid resonance, and engineering tips for optimizing load cell accuracy. Natural frequency serves as the definitive boundary for the bandwidth of a force measurement system and for structural integrity. Accurate data acquisition from load cells relies on maintaining a clear separation between the application's operational frequency and the resonant frequency of the physical test loop.
INTERFACE TECH TALK Thermal Specifications 1

How Do Thermal Specifications Influence Sensor Selection?

Interface Tech Talk details the differences between compensated and operating temperature ranges in load cell specifications. Thermal variables influence sensor accuracy, the mechanics of static deflection. Thermal gradient, material, strain gages, and repeatability are important when selecting a sensor. Only using capacity ignores the realities of the test environment. A load cell's compensated temperature range is the zone where accuracy is maintained by design. The operating temperature range is the boundary for hardware survival.

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.
