JS6000B type SF6 leak alarm monitoring system Introduction SF6 gas as the most stable greenhouse gases currently found, squat proved a strong spectral absorption characteristics at 10.5um place. SF6 laser transmitters use a carbon dioxide laser, narrowband filter, low-noise high-sensitivity photoelectric detection circuit, stable optical chopper, the reference light path and an open architecture and other advanced optical design methods and technology to achieve the treatment area measuring SF6 gas concentration in real time, on-line, open-sensitive infrared laser spectroscopy telemetry. SF6 laser transmitter is based on the analysis and comparison of associated gas detection methods on the same industry at home and abroad, the advanced open-sensitive mid-infrared optical path laser absorption spectroscopy technology for SF6 gas detection, complete with independent intellectual property rights, domestic initiative , reached the international advanced level of technology. Smart SF6 laser transmitter to overcome the traditional SF6 detector must be sampled in order to achieve point measurement only weakness, with an open optical path, no sampling can measure the concentration of SF6 gas in the region; analysis set gases, simulation inputs, digital inputs, protocol converters, communications interface conversion, transmission and switching output control and other functions into one, covering industrial control and monitoring systems required function collected at the scene, can be flexibly according to the specific requirements of various applications Configuring intelligent acquisition system. Smart laser transmitter integrated use of SF6 open-sensitive mid-infrared laser optical absorption spectroscopy, data acquisition and processing, communications technology in one of the open system platform, it's all functions are modular design, easy installation and maintenance works . Concentration system with automatic calibration function itself, does not require additional periodic calibration. Features: laser transmitter by the smart analog acquisition, and composition of the laser emission light intensity monitoring means, the laser receiver unit, the signal processing unit or the like, to achieve real-time monitoring area air SF6 gas concentration purposes. Smart SF6 laser transmitter function: analysis of the quantitative detection of regional air SF6 gas (using open-sensitive mid-infrared optical path laser absorption spectroscopy technique to eliminate the effect of fluctuations in the intensity of the laser itself and the external environment). Real-time display of gas concentration in the area of ??air SF6, arbitrarily set alarm levels, issued exceeded alarm function when the environment SF6 gas concentration exceeds the set alarm value. Each SF6 gas laser sensors monitor changes in the concentration of SF6 0.1 within the range of ~ 200m, without any sampling device, only one reflector, the reflector laser through the area to be monitored after being reflected back to the sensor, is realized on the entire SF6 concentration measurements in the optical path. Using laser absorption spectroscopy technique to detect, for SF6 gas leak detection, measurement accuracy can be higher than a millionth of detection resolution of 1ppm magnitude, and repeatable, reliable, long life, quantitative analysis, the use of open optical technology, to avoid sampling and monitoring to achieve a wide range of continuous space, simple operation, low failure rate. Technical parameters SF6 concentration detection range: 0 ~ 3000ppm, the error is less than 10ppm SF6 concentration detection Minimum Indication: 1ppm leak alarm threshold: 1000ppm or adjustable alarm error: <5% oxygen concentration detection range: 0 to 25.0% oxygen concentration detection error : <0.5% of the minimum oxygen concentration detection indication: 0.1% hypoxia alarm threshold: 18.0% or adjustable temperature detection range: -30 ~ 100 ℃ Relative humidity detection range: 0 to 100% detection point: the standard configuration 12:00 ( can be expanded to 36 points). Data logging function: automatic alarm event recording, mass storage, automatic updates. Alarm output: relay contact output empty, can be connected to RTU, while supporting RS485 alarm output. RTU remote start the fan support functions. Support infrared body detection, automatic start the fan or voice prompts. Fan Controller: Switch type: direct control of the fan power; pulse type: connected with the fan control switch. According scene matching. Fans started to support multiple modes: timed start, alarm starts automatically when you start someone, remote start, manual start. Host forms: Wall, 3U 19-inch standard cabinet, touch screen POS machine type floor; imitation windows interface, user friendly interface. Remote support via RS485 output measurement data such as: the door to install a large LED display, distance measurement parameters and immediately see the system operation.
