Description
GT-AT0616 Series Underground Shaft Combustible Gas Monitoring Device is an upgraded underground methane monitoring solution with multi-functional expansion. It uses a diffusion-type laser sensor to detect methane in the (0~100)%LEL range with ±2%F.S accuracy, supporting gas leak detection and infrared remote control. The DC3.6V battery-powered device has low power consumption and a three-year typical battery life, with adjustable sampling (20s~1800s) and heartbeat intervals (1h~24h). Equipped with 4G communication and GPS/Beidou positioning, it also adds groundwater level immersion monitoring and vibration early warning. With explosion-proof grades Ex ia IIC T4 Ga and Ex ia IIIC T200 130°C Da, IP68 protection, and engineering plastic material, it adapts to -40°C~70°C environments. It supports customized extensions (pipeline pressure monitoring, manhole cover anti-theft) and multiple installation methods, suitable for complex underground shaft monitoring needs.Specification
