WT-GL-100 distributed optical fiber type temperature sensing fire detector Introduction: This system is independently developed by our company. It is based on fiber Raman scattering technology and combines high frequency pulse excitation, optical wave multiplexing, optical time domain reflection and high frequency signal. Acquisition and weak signal processing technologies are mainly used for long-distance fire detection in tunnels, cables, oil tanks, gas tanks, etc. In view of the non-conducting nature of the fiber itself, the product is more suitable for fire detection in industrial fire projects where flammable, explosive and other hazardous areas and strong electromagnetic interference, corrosion, high temperature and explosion protection requirements. Executive standard: GB16280-2014 Features: The signal processing unit has a built-in optical fiber temperature measurement module, an industrial control integrated machine, a touch display, and a DC24V power supply (the power supply can be directly used). With information display, temperature measurement, information storage, fire linkage and other functions. The signal processing unit has a compact structure, convenient installation, high stability, strong compatibility, safety and reliability. Technical Parameters: Number of channels: 4 channels Temperature measurement distance: 0 to 5km (1 channel) 0 to 2.5 km (4 channels) Temperature range: -40°C～120°C Temperature measurement accuracy: ±1 °C Temperature resolution: ±0.1°C Measurement time: 2s / channel Power supply: 24VDC Relay: 24 channels Interface: USB/RS232/RS485 Operating temperature: -10 ° C ~ +50 ° C Storage temperature: -20 ° C ~ +60 ° C Relative humidity: ≤95% RH (no condensation) Dimensions (width × height × depth): 432mm × 528mm × 180mm
