Fiber optic grating osmometer

Model：ZZ-FBG-P035X

1、Summary

The Nanjing Zhunzhi ZZ-FBG-P035X fiber optic grating osmometer is mainly used to measure water pressure in rock mass, soil, concrete, embankments, pressure measuring pipes, drilling holes, and other areas, and can also reflect the water level at that point。

The core pressure measurement structure adopts a high elastic metal diaphragm. Water pressure acts on the diaphragm, causing micro displacement of the diaphragm. The fiber Bragg grating stretched on the diaphragm senses small changes, causing the reflection wavelength to drift. The measurement purpose is achieved by measuring the drift amount。
