In modern industrial and environmental monitoring, accurate and reliable detection of specific gases is crucial for ensuring safe production and achieving green management. Ethylene (C₂H₄), as an important industrial raw material and emission gas, has wide applications in chemical, warehousing, agricultural, and environmental monitoring. Tensensor's MQ-E3-C₂H₄ electrochemical ethylene sensor, with its superior performance and stable operation, is becoming a trusted monitoring tool for users in related industries.

    Core Product Advantages

    High Precision and High Sensitivity: The sensor utilizes electrochemical principles, with a linear relationship between the response current and gas concentration. It achieves a sensitivity of (0.070±0.015) μA/ppm and a resolution of up to 0.5ppm, enabling rapid detection of subtle changes in ethylene.

    Wide Linear Range and Strong Anti-interference Capability: Covering a range of 0–100ppm with a maximum measurement limit of 200ppm, it exhibits excellent linear output characteristics. In complex industrial environments, the sensor shows extremely low response to common interfering gases such as hydrogen sulfide and sulfur dioxide, significantly improving detection reliability.

    Excellent Stability and Long Lifespan: Repeatability error is less than 2%, monthly stability is better than 5%, and it maintains stable output over a wide temperature range of -20℃ to 50℃. Designed for a lifespan of up to 3 years, it effectively reduces maintenance and replacement frequency.

    Low Power Consumption and Easy Integration: No bias voltage is required for operation; the recommended load resistance is only 10Ω, making it suitable for integration into various portable and stationary detection devices, contributing to system energy saving and miniaturization.

Wide Range of Applications

    This sensor is not only suitable for monitoring ethylene leaks in industrial processes such as petrochemicals and synthetic materials, but also widely used for ethylene concentration control in fruit and vegetable storage and transportation environments, and for real-time monitoring of atmospheric emissions in the environmental protection field. Its robust structural design and stringent protection requirements ensure continuous and stable operation even under harsh conditions.

Easy to Use and Maintain

    The sensor supports a pressure range of ±10% of standard atmospheric pressure and a humidity range of 15%–90% RH. Clear usage and storage guidelines are provided, such as prohibiting soldering during installation, aging for 48 hours before use, and avoiding contact with organic solvents, helping users easily achieve long-term reliable operation of the system.

    In today's world where intelligent and green development are becoming mainstream, choosing a high-performance, stable, and reliable gas sensor is an important commitment to production safety and environmental responsibility. The MQ-E3-C2H4 ethylene sensor, with its excellent overall performance, strong environmental adaptability, and long lifespan design, has become an indispensable "sensing core" in industrial and environmental monitoring systems.
