Fiber Bragg Grating Piezometer

The Fiber Bragg Grating Piezometer is a high-precision water pressure monitoring device based on fiber Bragg grating sensing technology. The product uses a high-elastic metal diaphragm as the core pressure-sensing element. The small deformation of the diaphragm caused by water pressure changes the reflected wavelength of the fiber Bragg grating, thereby enabling accurate measurement of water pressure. The product features high measurement accuracy, high sensitivity, and good stability. It is suitable for seepage pressure monitoring inside rock masses, soil, concrete, and various hydraulic structures, and can also be used to monitor water level changes at monitoring points, providing reliable data support for engineering safety monitoring and long-term operation management.
