Supply Hunan power plant sulfur hexafluoride (SF6) gas concentration alarm

GRI-9106-R-SF6 SF6 intelligent fixed infrared alarm detector / fixed SF6 detector / power of professional SF6 infrared detector / GIS room IR SF6 monitoring system / sulfur hexafluoride SF6 circuit breaker special infrared detector / SF6 quantitative infrared detector / SF6 tracer detector / Guorui instrument SF6 detector I. Product Overview GRI-9106-R-SF6 is a Division I developed a high-performance intelligent infrared fixed SF6 gas detection alarm, High-performance, low-power microprocessor to ensure product performance and stability, real-time monitoring of SF6 gas concentration. Mainly used in petroleum, chemical, metallurgy, mining, fire, gas, environmental protection, electricity, telecommunications, paper, printing and dyeing, food reserves, urban water supply, sewage treatment, food, brewing, research, education, defense and other places. Second, the main features of using proof cast aluminum housing for a variety of indoor and outdoor environments, field sensor hot-swap function for easy sensor replacement and aftermarket. By sealing steel pipe and Guorui instrument GRI-9800 series supporting the use of alarm host controller or PLC to provide system alarms. This product can be via infrared remote control operation, the calibration can be achieved without opening the cover alone, without confirmation operating environment security. If necessary, you can also provide built-in alarm relay type, can be used as an independent monitoring unit control peripherals. While RS485 and 4 ~ 20mA (three-wire) digital / analog signals, digital output, HART protocol output. Segment type LCD big screen live display of gas concentration gas concentration unit selectable (eg ppm, mg/m3), with instrument status, fault, and communication error prompts. Can be set high and low alarm points, two sound and light alarm. Two relay can control peripheral devices (such as fans and sound and light alarm) action. Round die-cast stainless steel housing for offshore platforms, as well as temperature, humidity and other harsh environments. With good sealing, corrosion resistance, explosion and anti-EMI, RFI functionality.
