O2 Oxygen Gas Detector Transmitter Oxygen Sensor

Product Features

Engineered for uncompromising safety in volatile industrial environments, this oxygen gas detector transmitter combines precise electrochemical analysis with rugged physical construction. Every unit is designed to provide facility managers and safety engineers with immediate, actionable atmospheric data, ensuring personnel safety in confined spaces and critical operational zones. The robust build quality is immediately apparent in its weight and finish, reflecting a design philosophy centered on long-term reliability.

1. Precision Oxygen Monitoring

Configurable for O2 detection ranges of 0-25%vol or 0-30%vol, ensuring highly accurate atmospheric evaluation and rapid response to oxygen depletion or enrichment in confined spaces.

2. Rugged Mounting Architecture

The physical installation utilizes a specialized triangle hole design, offering a secure, tactile mounting process. This mechanical configuration provides exceptional stability against severe industrial vibrations, ensuring the heavy-duty enclosure remains firmly anchored to structural supports.

3. Advanced Sensing Core

Equipped with imported electrochemical sensors, the unit delivers exceptional sensitivity and reliable continuous monitoring. It maintains low baseline drift even during prolonged exposure to complex chemical environments, achieving a rapid response time of ≤60 seconds.

4. Resilient Environmental Protection

The gas detector features a heavily sealed waterproof and dustproof design side. It is engineered to perform flawlessly within a demanding working humidity range of 15-95% (RH), safeguarding the internal circuitry from moisture ingress and particulate damage.

5. Versatile Integration

Supports standard 2 or 3 wires configurations, outputting a reliable 4-20mA standard signal that interfaces directly with existing PLC and DCS control architectures for centralized facility management without compatibility issues.

6. Uninterrupted Atmospheric Analysis

Designed to continuously measure the gas concentration in the air. Operators can manage settings via an infrared remote control, allowing for immediate calibration adjustments and alarm configuration without needing to open the explosion-proof housing in hazardous zones.

7. Multi-Gas Adaptability

While optimized for oxygen, this model also can detect LEL/CO/ H2S/ H2/ SO2/ NH3/ NO/ NO2/ CL2/ O3/ O2/ CO2/ PH3/ HCL/ HCHO/ C6H6, etc. according to your need, providing a unified hardware standard across diverse facility requirements.

This precise tiering allows safety protocols to initiate automated ventilation or evacuation procedures well before hazardous concentrations become critical, providing a crucial buffer for personnel security.

Industry Applications & Full-Lifecycle Support

Securing hazardous work zones requires more than just accurate sensors; it demands a comprehensive approach to environmental safety. This oxygen gas detector transmitter is heavily deployed across demanding sectors, including chemical processing plants, metallurgical refineries, underground utility galleries, and specialized medical facilities. In these environments, the tactile, heavy cast-aluminum housing provides immediate physical reassurance of its durability. The Ex dIICT6 explosion-proof rating ensures the enclosure safely contains any internal ignition, preventing it from interacting with external volatile atmospheres, while the IP55 protection rating shields against aggressive dust and water jets common in industrial washdowns.

Beyond the physical hardware, procurement teams benefit from our extensive technical support infrastructure built on years of specialized manufacturing experience. We provide detailed CAD drawings for seamless architectural integration, comprehensive technical manuals, and direct remote installation guidance to ensure correct deployment. Furthermore, our dedicated service teams offer scheduled gas calibration protocols, ensuring the imported electrochemical sensors maintain their strict ≤±5%F.S. error rate over years of continuous operation. This end-to-end support significantly reduces the total cost of ownership, minimizes production downtime, and mitigates trial-and-error risks during critical facility upgrades.
