Fiber Bragg Grating Pressure Gauge

Model：ZZ-FBG-P20

1、Summary

The Nanjing Zhunzhi ZZ-FBG-P20 fiber optic grating pressure gauge is mainly used to measure the pressure of pressure vessels and pipelines. It adopts the standard M20 * 1.5 interface method and can directly replace pressure gauges, electronic pressure gauges, etc. It is suitable for pressure measurement in various occasions。

The core pressure measurement structure adopts a high elastic metal diaphragm, and the 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。
