Introduction

FBG Strain Sensor

The FBG strain sensor is mainly used to monitor the stress and deformation of various structural surfaces. The sensor is packaged with high-performance nickel-iron alloy with low coefficient of thermal expansion and installed on the surface of the object being measured by spot welding/bonding, which will not cause any damage to the surface of the object being measured. Due to its small size and easy installation, it is more suitable for small spaces and laboratories, as well as occasions where the object being measured is not easily damaged.
