Monitoring railway infrastructure & rolling stock.
PhotonFirst is provider of innovative sensing solutions for the railway industry. Our chip-based technology utilizes Fiber Bragg Grating (FBG) sensors to enable real-time condition-based monitoring of rail and rolling stock. This enables both infrastructure owners and rolling stock operators to improve their operations and maintenance processes.
Why Fiber Optic Sensing in railway?
EMI-immune sensors enable precise measurements in EMC environments
The sensors enable high frequency measurements (20kHz)
Cost-competitive compared to traditional electrical solutions
Application
We actively collaborate with our customers in the field to understand the complexities of their assets
The optical fiber becomes the sensor with FBG-based technology
Fiber optic sensors use light signals to detect various physical properties by observing changes in the light as it travels through the fiber. These changes can be due to temperature, pressure, strain, or other environmental factors.
