FBG Liquid Level Sensor
The MAS- FBG-HLS static level is composed of a series of high-precision FBG liquid level sensors and liquid storage tanks, and the liquid storage tanks are connected by connecting pipes. The reference tank is placed at a stable horizontal base point, and other liquid storage tanks are placed at different positions with approximately the same elevation. When other liquid storage tanks rise and fall relative to the reference tank, it will cause the liquid level in the tank to rise or fall. By measuring the change of the liquid level and understanding the lifting and deformation of the measured point relative to the horizontal base point, the settlement of 0.05mm can be monitored. Mainly applicable to dams, bridges, tunnels, subways, railways, roadbeds, cutting, and bridge transition sections, such as the need to monitor deflection, settlement and vertical deformation of the occasion.
Overview
The FBG-HLS fiber grating static level is a high-precision pressure system designed to measure relative settlement at multiple points. The sensor consists of a pressure fiber grating and a temperature fiber grating. The sensor sensing membrane senses water pressure changes and transmits them to the pressure grating. The temperature grating performs temperature compensation on the sensor to correct the sensor data drift caused by ambient temperature changes.
Monitoring the settlement deformation of the structure, bridge deflection and vertical deformation of the occasion, highway, subway, railway, roadbed, cutting settlement automatic monitoring system.
Characteristic:
- Anti-electromagnetic interference, electrical insulation;
- Built-in temperature compensation gratint;
- Can be mixed with other types of fiber grating sensors to easily build a distributed monitoring network;
Application scenarios:
- Subsidence monitoring of infrastructure such as bridges, nuclear power plants, reservoirs and dams, hydropower stations, buildings, and steel structures;
- Settlement monitoring of structures in petrochemical industries such as petroleum storage tanks and petrochemical storage tanks;
