PSR-12-223 Oxygen Gas Sensor For Industrial Manufacturing Environmental Monitoring

1. Product Features:

• High Detection Precision: Adopts high-sensitivity electrochemical or catalytic bead sensing elements (varies by target gas type), enabling accurate measurement of low-concentration gas components and minimizing detection errors.
• Broad Environmental Adaptability: Maintains stable performance in harsh working conditions, including a wide temperature range (-20℃ ~ +50℃, or extended -40℃ ~ +60℃ for optional versions) and non-condensing high humidity (15% ~ 90% RH), with low performance drift caused by environmental changes.
• Flexible Output Modes: Supports dual output options—analog signals (4-20 mA DC / 0-5 V DC) for direct connection to PLC, DCS, or other industrial control systems, and optional digital signals (RS485 with Modbus RTU protocol) for long-distance remote data transmission and monitoring.
• Excellent Long-Term Stability: Features low zero drift (≤ ±2% F.S. per year in clean air) and low sensitivity drift, reducing the frequency of calibration and maintenance, and lowering long-term operation costs.
• Enhanced Safety & Durability: Complies with industrial safety standards (e.g., optional ATEX, IECEx certifications for hazardous areas) to ensure safe use in explosive or toxic gas environments. The housing is made of ABS plastic or stainless steel with IP65/IP67 protection rating, effectively resisting dust, water splashes, and mechanical impacts.
• Optional Anti-Interference Design: Offers optional built-in filters (e.g., dust filters, H₂S/NO₂ interference filters) to reduce the impact of impurities or cross-sensitive gases on detection results, improving measurement reliability in complex gas environments.

2. Typical Applications:

• Industrial Manufacturing: Petrochemical plants, refineries, natural gas processing stations, and chemical factories—used for real-time monitoring of combustible gas (e.g., methane, propane) leaks or toxic gas (e.g., harmful VOCs) emissions to prevent explosion or personnel poisoning risks.
• Commercial & Residential Buildings: Shopping malls, hotels, residential communities, and catering facilities—monitors indoor natural gas, liquefied petroleum gas (LPG) leaks, or harmful gases from decoration materials, ensuring indoor air safety for occupants.
• Environmental Monitoring: Environmental protection departments, indoor air quality (IAQ) testing institutions, and industrial waste gas treatment sites—detects toxic or harmful gases in ambient air or industrial exhaust, assisting in environmental pollution control and compliance testing.
• Automotive & Marine Sectors: LPG/CNG-fueled vehicles (e.g., taxis, buses) and marine vessels—installed to monitor gas leaks in fuel systems, triggering alarms promptly to avoid fire or explosion hazards during operation.
• Municipal Infrastructure: Gas pipeline networks, sewage treatment plants, and waste incineration plants—monitors gas leaks along pipeline routes or harmful gas emissions from waste treatment processes, ensuring the safety of municipal operation and surrounding environments.
