- Highway safety monitoring
- Slope monitoring
- Soil stress in building foundations such as earth and rock dams, breakwaters, revetments, and dock walls
- Soil stress in foundations of high-rise buildings, bridge piers, retaining walls, tunnels, subways, airports, and other buildings
- The compressive stress between the foundation and soil of buildings such as highways, railways, and anti-seepage wall structures
Fibre Optic Soil Pressure Sensor YOSC-OFSP
YOSC-OFSP fibre optic soil pressure sensor is a force sensor used for both static and dynamic measurements. Its principle is that the elastic structure undergoes elastic deformation under external forces, and the fibre optic grating pasted on the elastic structure also undergoes deformation.
The product has a simple structure, no electronic components, high system reliability, and can be widely used for long-term monitoring of soil pressure in structures such as earth dams, embankments, slopes, and roadbeds.
