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 Technical Parameters: Number of channels: 2, 4, 6, and 8 channels (can be customized for any even channel) Temperature measurement distance: 0～10km (1 channel) 0 to 2.5 km (8 channels) Temperature range: -40 ° C ~ 120 ° C (higher temperature fiber needs to be selected, up to 500 ° C) Temperature measurement accuracy: ±1 °C Temperature resolution: ±0.1°C Positioning accuracy: 0.5m Measurement time: 2s / channel Power supply: 220VAC 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 × 175mm × 455mm
