Advanced Railway Safety with Fiber Bragg Grating Sensors
The Axle Counter Plus (ACPS) counts the number of train axles and provides real-time information about track section occupancy. This technology utilizes Bragg Grating optical sensors, offering highly reliable axle counts and section status updates.
FBG sensors are optical sensors that utilize light reflection within optical fibers to detect changes in physical parameters such as strain, temperature, and pressure. These sensors have a periodic variation in the refractive index along the fiber core, which reflects a specific wavelength of light, called the Bragg wavelength, while allowing other wavelengths to pass. When external forces (strain or temperature changes) are applied, the spacing of the grating and the refractive index change,shifting the reflected wavelength.
Accurate and reliable measurements of strain, temperature, and pressure.
Multiple FBG sensors can be embedded along a single fiber, enabling simultaneous monitoring of several points without extra wiring.
