Product Description:
YJJ AFBR-S6PY2626 Dual-Channel Thermoelectric Infrared Sensor for CH4 / Carbon Hydrogen Gas Specialized Use
Features:
I. Core Parameters (Typical Values)
1. Channels and Filters
Channel 1 (Reference): 3.91 μm / 90 nm (absorbs no CH₄)
Channel 2 (Measurement): 3.30 μm / 160 nm (CH₄ characteristic absorption peak)
2. Electrical and Performance
Output: Analog voltage (built-in CMOS amplifier, single power supply)
Signal-to-Noise Ratio SNR: ≈10,000 (high sensitivity)
Operating Frequency: 1–40 Hz (commonly 10–15 Hz)
Response Speed: Fast, suitable for dynamic gas measurement
Power Supply: 2.7–5.5 V (typical 3.3 V/5 V)
Operating Temperature: -20 ℃ ~ +70 ℃
Life Span: Long life, no consumables, resistant to vibration and moisture
Certification: RoHS compliant
3. Detection Targets
Main: Methane CH₄ (natural gas, biogas)
Compatible: Other hydrocarbons (propane, butane, VOCs)
II. Working Principle (NDIR Non-Dispersive Infrared)
Infrared light source emits broadband infrared light;
Gas Absorption: CH₄ has strong absorption at 3.3 μm, while the reference channel (3.91 μm) does not absorb;
Dual-channel Differential: The measurement channel signal decays with CH₄ concentration, and the reference channel compensates for light source drift, temperature, and interference;
Thermosensitive Element converts infrared energy changes into voltage signals, output proportional to gas concentration;
Film Process + Built-in High-Resistance Amplifier, high signal-to-noise ratio, low drift, strong stability.
III. Main Applications
1. Methane / Natural Gas Detection (Most Common)
Household / Industrial Gas Alarm (CH₄ Leakage)
Natural Gas Pipeline, Valve, Station Inspection
Coal Mine Methane (CH₄) Monitoring Alarm
Biogas Pits, Biogas Equipment Concentration Monitoring
2. Industrial Hydrocarbon Gas Detection
Petrochemical, Refinery, Chemical Zone VOC / Hydrocarbons Monitoring
Gas Station, Oil Depot Gas Detection
Industrial Process Gas Analysis
3. Alternative to Traditional Sensors
Alternative to Catalytic Combustion (Easy poisoning, short lifespan)
Alternative to Electrochemical (Short lifespan, specific gas only)
Suitable for explosion-proof, long life, maintenance-free scenarios
4. Others
Environmental Monitoring, CH₄ Emission from Landfills
Agricultural Greenhouse Gas Monitoring
