Product Overview of Fiber Bragg Grating Temperature Sensing Fire Detector:
The seamless steel pipe Fiber Bragg Grating temperature sensing fire detector is composed of fiber connectors, all-metal stainless steel seamless pipe, and FBG/FBG arrays (FBGs). It can be in single-ended multipoint form or double-ended serial form. When combined with the Fiber Bragg Grating fire alarm host, it can form a Fiber Bragg Grating temperature sensing fire alarm system.
OFSCN® capillary seamless steel tube FBG temperature sensing fire detectors can be directly immersed, buried, inserted, surface-mounted, adhesive-mounted, or bundled into the tested structure for temperature monitoring and fire warning. They are especially suitable for use in traffic tunnels, petroleum, natural gas pipelines, chemical, metallurgical, power, firefighting, energy, storage, military, nuclear industries, and other places.
