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.

Frequently Asked Questions
Q
What type of gas does the GT-AT0616 Series monitor, and what is its detection range?
The GT-AT0616 Series is designed to monitor methane (CH₄) using a diffusion-type laser sensor. Its measurement range covers (0~100)%LEL (Lower Explosive Limit), making it suitable for detecting combustible gas concentrations in underground shaft environments.
Q
How long does the battery last, and can the sampling frequency be adjusted?
The device is powered by a DC3.6V battery with a typical battery life of three years. The sampling period is adjustable from 20 seconds to 1800 seconds (default: 30 minutes), and the heartbeat interval can be set between 1 hour and 24 hours (default: 24 hours), allowing users to balance monitoring frequency with battery conservation.
Q
What explosion-proof certifications does this device hold?
The GT-AT0616 Series carries dual explosion-proof certifications: Ex ia IIC T4 Ga (for gas hazardous environments) and Ex ia IIIC T200 130°C Da (for dust hazardous environments). These certifications ensure safe operation in highly flammable underground conditions.
Q
Does the device support remote monitoring and location tracking?
Yes. The device is equipped with 4G wireless communication for real-time data transmission and integrates both GPS and Beidou dual-mode positioning systems. This enables accurate location tracking and remote monitoring of underground shaft sites without the need for additional infrastructure.
Q
What additional monitoring functions does the GT-AT0616 Series offer beyond gas detection?
Beyond methane detection, the GT-AT0616 Series features groundwater level immersion monitoring and vibration early warning functions. It also supports customized extensions such as pipeline pressure monitoring and manhole cover anti-theft systems, making it a comprehensive multi-hazard monitoring solution for complex underground environments.
Q
What are the installation options and environmental operating limits for this device?
The device supports three installation methods: wall mounting, pole mounting, and ground installation, providing flexibility for various underground shaft configurations. It is rated IP68 for full dust and water ingress protection, operates across a temperature range of -40°C to 70°C, and withstands humidity up to 100% RH (non-condensing), ensuring reliable performance in harsh subterranean environments.
