Product Description:
The GD3000-E Combustible Gas Monitoring Device for Underground Wells adopts high-performance laser gas sensors and microcomputer technology, designed with excellent low-power consumption technology. It features low power consumption, good repeatability, long service life, easy installation, simple maintenance and convenient operation.
The device is battery-powered. Via the 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 intervals or triggered by events such as alarms and faults. Combined with the system software, maintenance operations including statistics, query and backup of gas concentration data at on-site monitoring points can be realized.
It is suitable for gas concentration monitoring in spaces such as gas valve wells, water supply and drainage wells, power wells, communication wells, and above-ground marker posts of gas pipelines.
Product Features:
※ Communication function: Adopts 4G-CAT1 or NB-IoT communication mode, enabling data transmission to the system platform via wireless communication network.
※ Data content: Combustible gas concentration, temperature, water immersion status, battery voltage (power level), wireless network signal quality, etc.
※ Detection functions: Automatic/manual detection of combustible gas concentration, temperature, water immersion status and battery voltage (power level).
※ "Black box" function: Real-time storage of collected data ensures no data loss, and stored data can be read via mobile devices.
※ Display function: Local display via indicator lights.
※ Extended display: Bluetooth communication.
※ Alarm functions: Combustible gas concentration alarm, water immersion alarm, battery alarm, and vibration alarm.
※ Anti-theft positioning function supporting multi-satellite systems (GPS, GLONASS, BDS and QZSS) (optional).
※ Vibration detection support with adjustable vibration threshold.
※ Firmware upgrade function: The firmware of the underground well combustible gas monitoring device can be updated via the server or debugging tools.
