Surface-mounted FBG temperature sensor

This surface-mounted FBG temperature sensor uses the wavelength shift of a fiber Bragg grating to sense temperature changes, and is directly attached or fixed to the structure surface for measurement. It uses a stainless steel substrate and standard single-mode fiber, with an FC/APC connector, a center wavelength range of 1510–1590 nm, and a temperature sensitivity of about 28 pm/°C. Depending on the coating method, the polyimide-coated version can cover -40–300°C, and the bare FBG version can cover -40–1000°C. The product is suitable for structural temperature monitoring in fields such as bridge construction, wind power and heavy industry, and ancient building protection. The installation method is flexible, and the bow-shaped structure and material can be optimized according to project needs. If you have specific size, quantity, or operating condition requirements, welcome to contact us to confirm the configuration and quotation.
