PD-CWDnK linear Fiber Optic Pyrometer fire detector is a specific application of distributed fiber temperature detection （DTS） technology in the field of fire alarm. It is based on fiber Raman scattering technology and combines high-frequency pulse laser and light wave. Advanced technologies such as sub-multiplexing, optical time domain reflection, high-frequency signal acquisition and weak signal processing are mainly used for large-scale fire detection such as cables, tunnels, oil tanks and gas tanks. In view of the intrinsic safety characteristics of optical fiber, the product is more suitable for fire detection in industrial fire projects with flammable, explosive and other hazardous areas and strong electromagnetic interference, corrosion, high temperature and explosion-proof requirements. This product is mainly composed of fiber optic host and probe cable. Among them, the fiber optic host is responsible for fiber signal processing, alarm and parameter setting, etc. The probe cable is responsible for temperature collection at the site. The fiber optic host can also be connected to the fire alarm controller via RS485/232, CAN, and Ethernet interfaces to form a complete fire alarm system.
2.Structure and principle
Fiber Optic Pyrometer according to the optical time domain reflection （OTDR） of the fiber and the backward Raman scattering temperature effect of the fiber. The probe fiber is placed in the space to be tested, and the fiber host emits the laser beam into the probe cable, and real-time collects Raman scattered light with real-time temperature information scattered along the fiber, and the fiber host controls the light. The signal is analyzed and processed to derive temperature distribution information over the entire fiber. The temperature information is compared with a preset alarm parameter value. When the alarm condition is met, the fiber optic host issues a fire alarm sound and light indication, and can output an alarm signal to the fire alarm controller.
