Model:
HMJ1012-WLQ
Product Overview:
The cable gas monitoring sensor is a specialized device designed to detect various gases generated during the operation of underground power cables, typically installed in cable shafts, tunnels, and ducts. Over time, due to insulation aging, overheating, or partial discharge, cables may emit characteristic gases such as hydrogen (H₂), acetylene (C₂H₂), methane (CH₄), and carbon monoxide (CO). The type and concentration of these gases provide valuable insights into the operational status and hidden faults of the cable system. By detecting these gases in real time, the sensor helps identify potential failures early, ensuring the safe and stable operation of the power grid.
Key Features:
- High Sensitivity: Capable of detecting extremely low concentrations of target gases to provide early warnings of potential cable issues.
- Excellent Stability: Constructed with high-temperature and corrosion-resistant materials for reliable operation in harsh environments.
- Alarm Function: When gas concentration exceeds preset safety thresholds, the system triggers alerts for timely intervention.
- Low Power Consumption: Designed for energy efficiency and continuous long-term operation.
- Easy Installation & Maintenance: Compact design allows for convenient installation and simple upkeep.
