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.
