What Is a Strain Sensor

에이 strain sensor is a precision measurement device that detects and quantifies mechanical deformation in materials and structures by converting physical strain into measurable electrical or optical signals. These sensors play a crucial role in structural health monitoring, providing real-time data about stress distribution, 부하 조건, and material behavior under various operating conditions.

Strain measurement sensors operate on various physical principles including resistance changes, optical wavelength shifts, frequency variations, and capacitance modifications that correlate directly with mechanical strain. Modern strain sensors provide high accuracy measurements with excellent long-term stability, enabling continuous monitoring of critical infrastructure and equipment throughout their operational lifecycle.
