Mipex-02-1-II-1.1A Infrared Gas Sensor For Detecting Methane (CH4) Concentration
1. Product Features:
Ultra-low power consumption: Average power consumption is less than 5 mW, ideal for battery-powered portable detection devices and scenarios requiring long-term continuous operation.
Wide measurement range & high accuracy: Supports measuring up to 100% VOL methane (CH₄) and 100% LEL hydrocarbon (CₙHₘ, calibrated to propane C₃H₈); accuracy reaches ±0.1% VOL or 5% of reading for CH₄, and ±3% LEL or 5% of reading for C₃H₈, meeting strict industrial detection standards.
Strong environmental adaptability: Operates normally under relative humidity up to 98% (non-condensing) and temperature ranges of -10~+40°C (Group I) / -40~+60°C (Group II); almost no interference from humidity, suitable for harsh industrial and mining environments.
High safety level: Complies with multiple international explosion-proof standards (e.g., Ex ia I Ma/Ex ia IIC T5 Ga, UL913 Class I Division 1); features "ia" intrinsic safety protection without sintering, ensuring safe use in flammable and explosive areas.
Stable & low-maintenance: Resistant to "poisoning" gases that affect catalytic sensors; maintains long-term stability with simple calibration requirements, reducing equipment maintenance frequency and costs.
Easy integration: Built-in microcontroller and digital UART interface; compact size (Φ20x16.6mm without pins) and lightweight (5.5~16.6g based on material), enabling easy integration into various detection instruments and systems.
2. Product Applications:
Mining industry: Used in underground coal mines and metal mines to detect methane (CH₄) leaks, preventing gas explosions and ensuring the safety of underground operations and personnel.
Oil & gas sector: Applied in oil exploration sites, refineries, and natural gas pipelines to monitor hydrocarbon (CₙHₘ) and methane concentrations, avoiding fire or explosion risks from gas leaks.
Chemical & petrochemical industry: Integrated into safety monitoring systems of chemical plants and petrochemical facilities to track methane and carbon dioxide (CO₂) emissions, ensuring compliance with environmental and occupational health standards.
Power & utility industry: Used in power plants, water treatment plants, and wastewater treatment facilities to detect flammable gas leaks in equipment operation environments, protecting production safety.
Portable detection devices: Assembled into handheld gas detectors for on-site emergency testing in hazardous material (hazmat) handling, fire rescue, and biogas engineering scenarios, providing real-time gas concentration data.
