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
❓
What type of gas does the GT-AT0616 Series monitor, and what is its detection range?
The GT-AT0616 Series is specifically designed to monitor methane gas using a diffusion-type laser sensor. It covers a measurement range of (0~100)%LEL with an accuracy of ±2%F.S, making it highly reliable for combustible gas leak detection in underground shaft environments.
❓
How long does the battery last, and can the sampling interval be customized?
The device is powered by a DC3.6V battery with a typical battery life of three years under standard operating conditions. The sampling period defaults to 30 minutes per reading but is fully adjustable within a range of 20 seconds to 1800 seconds. The heartbeat interval defaults to 24 hours and can be adjusted between 1 hour and 24 hours.
❓
Is the GT-AT0616 certified as explosion-proof, and what protection rating does it carry?
Yes, the GT-AT0616 holds dual explosion-proof certifications: Ex ia IIC T4 Ga for gas environments and Ex ia IIIC T200 130°C Da for dust environments. It also carries an IP68 protection rating, ensuring full resistance to dust ingress and continuous water immersion, making it suitable for harsh underground shaft conditions.
❓
What communication and positioning technologies are built into the device?
The GT-AT0616 is equipped with 4G wireless communication for real-time data transmission, as well as integrated GPS and Beidou satellite positioning systems. This dual-positioning capability ensures accurate location tracking even in complex underground or urban infrastructure environments.
❓
What additional monitoring functions does the GT-AT0616 support beyond gas detection?
Beyond methane gas detection, the GT-AT0616 supports groundwater level immersion monitoring and vibration early warning as standard expanded functions. It also supports customized extensions including pipeline pressure monitoring and manhole cover anti-theft alerts, making it a comprehensive multi-functional underground monitoring solution.
❓
What are the available installation methods and working environment conditions?
The GT-AT0616 supports three installation methods: wall-mounted, pole-mounted, and ground installation, providing flexibility for various underground shaft configurations. It operates reliably across a wide temperature range of -40°C to 70°C and humidity up to 100% RH (non-condensing), and functions within an atmospheric pressure range of 86~110 kPa.
