In the field of industrial production and safety monitoring, accurate and reliable monitoring of carbon dioxide concentration is crucial. Tensensor's TX721-A2 infrared carbon dioxide gas sensor, with its advantages of high precision, strong stability, and explosion-proof safety, has become an ideal choice for gas monitoring in industrial environments.

TX721-A2 Infrared Carbon Dioxide Gas Sensor

Core Advantages: Accuracy, Stability, and Safety Combined

    The TX721-A2 employs non-dispersive infrared (NDIR) detection, unaffected by oxygen interference, exhibiting excellent long-term stability and resistance to moisture interference, with a service life exceeding 5 years. The sensor provides dual interfaces: UART digital output and 0.4–2V analog voltage output, supporting various customized ranges (up to 10% Vol), and features built-in temperature compensation to ensure linear and reliable output over a wide temperature range of -20℃ to 60℃.

    Its fast response time (T90 < 30 seconds) allows for real-time capture of gas concentration changes, making it suitable for industrial safety and process control scenarios requiring rapid response. Furthermore, the sensor has an IP54 protection rating, enabling stable operation in harsh industrial environments such as high humidity and dust.

Intrinsically Safe Design, Suitable for Explosion-Proof Environments

    This sensor has passed national explosion-proof certification, with an explosion-proof mark of Exib IIB T4 Gb, suitable for Zone 1 and Zone 2 explosive environments. When used with intrinsically safe power supplies and safety barriers, it can be safely applied in hazardous locations such as chemical plants, oil and gas plants, and coal mines, providing reliable protection for personnel and equipment.

Wide Range of Applications

    Industrial Safety Monitoring: Real-time monitoring of CO₂ concentration in confined spaces, reaction units, and storage tank areas to prevent the risk of gas accumulation.

    Production Process Control: Precise control of CO₂ concentration in processes such as fermentation, welding, and greenhouse aquaculture to improve process consistency.

    Energy Efficiency and Air Quality Management: In conjunction with HVAC systems, it enables fresh air linkage and energy consumption optimization, improving indoor environmental quality.

Intelligent Communication, Easy Integration

    The sensor supports the standard Modbus-style UART communication protocol, with concise and clear commands, facilitating integration into PLCs, DCSs, IoT terminals, and other systems. Users can read concentrations and perform zero-point and span calibrations via commands, enabling intelligent system maintenance and remote management.

    The TX721-A2 is not only a high-performance CO₂ sensor, but also a key sensing node for industrial safety, green production, and the Internet of Things. Its high precision, intrinsic safety, long lifespan, and ease of integration make it the preferred solution for industrial customers in the field of gas monitoring.
