Structure of Fiber Optic Weighing Sensor
The system consists of a pneumatic tube filled with an incompressible fluid and embedded in a rubber pad, a diaphragm designed to convert pressure into displacement, and an optical displacement sensor. YOSC-OFW fibre optic weight 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. Optical fibre sensing is an ideal method for measuring parameters such as temperature and strain or even chemical or acoustic signals over long distances. Further there are many points why fiber optic...
