Fiber Bragg grating earth pressure meter
Product Name: Fiber Bragg grating earth pressure meter
XH-P01 fiber grating osmotic pressure sensor adopts optical fiber metallized laser welding technology and temperature self compensating package structure, which has the characteristics of high measurement precision, stable long-term work and easy installation and use. The pressure sensitive element and transmission line in the sensor are all single mode fiber, which is not charged and is not affected by electromagnetic interference. It can work steadily on the dangerous environment of strong electromagnetic interference and flammable and explosive. It is widely used in the monitoring of the pore water level or water pressure in the earth dams, concrete buildings, bedrock, boreholes (wells), foundations, pipes and pressure vessels in the petrochemical, electric power and water conservancy and hydropower projects.
