Product Description:
YJJ OOA101 Solid-State Electrolyte Oxygen Sensor Medical Equipment
Features:
I. Core Parameters (25℃, ambient air)
Target gas: Oxygen O₂
Measurement range: 0–100% O₂ (full range coverage)
Output signal: 7–13 mV (@20.9% O₂, linear output)
Response time T90: < 5 s (extremely fast response)
Operating temperature: 0℃ ~ +50℃ (normal environment)
Storage temperature: -20℃ ~ +60℃
Life span: 5 years + (solid-state electrolyte, anti-drying)
Shock resistance: Excellent (solid-state electrolyte, resistant to vibration)
Certifications: PTB-A 18.10, RoHS, EN ISO 13485
II. Working Principle
Polarographic (Galvanic Cell) Principle:
Oxygen passes through the permeable membrane and enters the solid-state electrolyte;
At the cathode, a reduction reaction occurs, while at the anode, oxidation takes place, generating a micro-voltage (mV level) proportional to the oxygen concentration;
Built-in solid-state electrolyte, no leakage, long lifespan, resistant to high and low temperatures and vibrations;
Output directly connected to the mV level circuit, no need for complex amplification.
III. Main Applications (Core Scenarios)
1. Medical Equipment (Most mainstream)
Respirators, anesthesia machines: Monitoring inhalation / exhalation oxygen concentration, preventing hypoxia / oxygen poisoning
Monitoring devices, oxygen analyzers: Monitoring of medical gas concentrations
2. Industrial Gas Monitoring
Air separation oxygen production: Online monitoring of high-purity oxygen / nitrogen
Enclosed spaces: Tunnel, mine, ship cabin, cold storage oxygen content alarm (preventing hypoxia)
Power / boiler: Oxygen content monitoring in flue gas (burning efficiency control)
3. Automotive and Exhaust Analysis
Exhaust analyzer: Detecting O₂ concentration in exhaust (fuel-air ratio)
Automotive maintenance testing equipment
4. Aerospace and Research
Cabin / compartment oxygen monitoring, laboratory gas ratio adjustment, environmental chamber
IV. Model Differences (Order Reference)
