Fiber Bragg Grating Soil Pressure Gauge
The HG-P01 fiber optic grating pressure sensor adopts fiber optic metallization laser technology and temperature self compensating packaging structure, which has the characteristics of high measurement accuracy, long-term stable operation, and easy installation and use. The internal pressure components and transmission lines of the sensor are all single-mode optical fibers, which are not charged and not affected by electromagnetic interference. They can work stably for a long time in hazardous environments with strong electromagnetic interference and flammable and explosive materials. Widely used in the monitoring of pore water level or water pressure in soil dams, concrete buildings, bedrock, boreholes (wells), foundations, pipelines, and pressure vessels in petrochemical, power, water conservancy and hydropower engineering.
