Product Description:
YJJ MP7227-DA 0-5%VOL 0-100%LEL MEMS Catalytic Combustion Gas Sensor for Combustible Gases
Features:
I. Core Parameters
1. Basic Specifications
Brand: SGX Sensortech (Polish production, Swiss brand), MEMS micro catalytic bead type (Pellistor)
Detected Gas: Mainly methane CH₄ (natural gas), compatible with propane, butane, alcohol, aliphatic hydrocarbon combustible vapors
Range: 0 - 5% VOL (0 - 100% LEL, methane explosion lower limit 4.4% VOL)
Power Supply: Rated DC 3V; Peak 50mA, average pulse power consumption **< 0.6mA (ultra-low power consumption, preferred for lithium battery devices)**
Form: SMT surface mount packaging, size Φ14.4 × 6.7mm, 3-pin direct-welded PCB
Response T90 ≤ 12s, low temperature and vibration environment drift is small, superior to traditional black bead catalytic sensors in anti-sulfurization poisoning
Explosion-proof Certification: ATEX, IECEx Ex-da IIC Ga intrinsically safe explosion-proof, suitable for explosion-proof instruments / underground equipment
Temperature and Humidity: -20℃ to +55℃, 5 - 95% RH without condensation; Lifespan typically 3 - 5 years
2. Electrical Characteristics
Bridge differential voltage output, linearly increases with the concentration of combustible gas; zero point stable, orientation influence extremely small (placement does not affect reading)
Supports continuous power-on / intermittent pulse power-on dual modes, pulse mode battery life is increased by tens of times
II. Product Features
Micro surface mount SMT, automated surface mount production, whole machine miniaturization
Ultra-low power consumption, portable battery detector preferred (one-time lithium battery, rechargeable lithium battery)
Explosion-proof explosion-proof packaging, can be directly used in explosion-proof equipment in hazardous Zone 1
Resistant to oil pollution, resistant to organic silicone poisoning, durable in harsh conditions such as kitchens / gas stations
III. Application Purposes
1. Civilian Gas Safety
Portable household gas leak detector (handheld gas leak detection for natural gas, liquefied gas)
Battery-powered independent gas alarm, countertop mini gas detector (battery-powered, no need for external power supply)
Built-in leak protection detection for wall-mounted boilers, gas water heaters
2. Industrial Safety
Portable four-in-one / single combustible gas detector (BW, domestic substitute for Delg portable instrument)
Municipal gas inspection instrument, underground pipe trench gas leak detection
Portable inspection alarm for gas stations, liquefied gas stations, mine gas portable instrument (compliant with explosion-proof certification)
