Fiber Bragg Grating Patch Strain Gauge
Model：ZZ-FBG-PE3000
1、Summary
The Nanjing Zhunzhi ZZ-FBG-PE3000 fiber optic grating patch strain gauge is mainly used to measure the strain on metal surfaces and concrete surfaces。
The matrix structure adopts a high elastic metal structure, and the fiber optic grating is fixed on the matrix using epoxy resin adhesive or oxygen free adhesive. During measurement, the sensor is subjected to tension and compression deformation, which drives the internal strain grating to stretch and compress, causing a change in the reflection wavelength. The change in the reflection wavelength is detected by the background demodulator to achieve the measurement purpose。
