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.
