Product Description：

GD2000-E Combustible Gas Monitoring Device for Underground Wells adopts high-performance laser gas sensors and microcomputer technology, matched with a new-generation low-power battery power supply design. It features low power consumption, excellent repeatability, long service life, easy installation and convenient maintenance.

Equipped with enhanced encryption algorithm and software architecture, the device supports unique key allocation for single unit to further ensure data security. Via local existing cellular communication network, it uploads gas concentration data, battery level, abnormality types and other information to the data center through wireless network at fixed time or triggered by events such as alarm and fault. Combined with platform software, it supports statistics, inquiry, backup and other maintenance operations of gas concentration data at on-site monitoring points.

This device is applicable to uninterrupted gas concentration monitoring and early warning in urban underground confined spaces including gas valve wells, water supply and drainage wells, power wells and communication wells.

Product Features：

※ Accurate measurement: The sensor adopts imported gas-sensitive elements with high precision and low zero drift.

※ Waterproof structural design: Special structure design enables reliable application in outdoor environments.

※ Lithium battery power supply: Powered by high-capacity lithium battery, which supports 3-year operation under normal monitoring state; the actual service life is subject to ambient conditions.

※ Detection functions: Automatic and manual detection of combustible gas concentration, temperature detection and water immersion detection; pressure detection, manhole cover displacement detection and GPS positioning are optional functions.

※ Communication functions: Supports 4G-CAT1 or NB-IoT, enabling data transmission to the system platform via wireless communication network.

※ Black box function: Real-time storage of collected data ensures no data loss, and stored data can be read through mobile equipment.

※ Encryption mechanism: Dynamic AES encryption is adopted for communication with the monitoring platform to guarantee high data security.

※ Self-diagnosis function: The device can perform self-diagnosis. It sends fault signals to the master station in case of sensor failure and low battery voltage with identifiable fault status. It can keep working for 15 days after low battery alarm, providing sufficient time for battery replacement.

※ Expansion function: Built-in Bluetooth communication function.

※ Firmware upgrade function: The firmware of underground well combustible gas monitoring device can be updated through server or debugging tools.
