As energy storage technology is rapidly deployed across various scenarios, safety remains a key focus for the industry. In relatively enclosed or semi-enclosed environments such as energy storage cabinets, small generator stations, and vehicle-mounted energy storage systems, carbon monoxide, as one of the key characteristic gases in the early stages of battery thermal runaway, makes effective monitoring of its concentration changes crucial for preventing accidents.

    Against this backdrop, Tensensor's MQ2-CO-Φ14×5 electrochemical CO sensor, with its superior performance, industrial-grade stability, and 10-year design life, is becoming a highly competitive choice in the field of energy storage safety monitoring.

MQ2-CO-φ14x5 CO Sensor

    Precise Sensing for Early Warning

    In energy storage applications, gas sensors not only need to be accurate but also fast-responding. The MQ2-CO-Φ14×5 sensor, employing fuel cell-based electrochemical principles, exhibits high sensitivity to carbon monoxide (1.2–3.5 nA/ppm) with a resolution of up to 1 ppm, enabling it to keenly detect changes in low-concentration gases. Its T90 response time is less than 30 seconds, allowing for rapid early warning in the initial stages of thermal runaway, providing valuable time for maintenance personnel.

    Simultaneously, this sensor boasts a wide linear range of 0–5000 ppm, maintaining stable output characteristics even under high-concentration shocks. This is of significant practical value for handling sudden gas releases that may occur in energy storage scenarios.

    Low Power Consumption and Long Lifespan, Perfect for Energy Storage System Operations

    Energy storage monitoring equipment often requires 24/7 uninterrupted operation. Power consumption and lifespan directly impact system maintenance costs and reliability. The MQ2-CO-Φ14×5 sensor exhibits excellent power consumption control, along with outstanding long-term stability and zero-point drift control (≤10ppm), maintaining reliable output within a temperature range of -20℃ to 60℃.

    Notably, its design lifespan of up to 10 years significantly reduces sensor replacement frequency and maintenance costs during the operational cycle of energy storage projects, making it particularly suitable for distributed energy storage and unattended sites.

    Strong anti-interference capability, adaptable to complex gas environments

    Energy storage cabinets often contain multiple gas sources that may cause cross-interference. The MQ2-CO-Φ14×5 has undergone rigorous calibration for cross-interference control, exhibiting extremely low response to common interfering gases such as nitrogen dioxide, sulfur dioxide, chlorine, and ammonia, effectively avoiding false alarms. This characteristic is especially important for energy storage scenarios requiring long-term stable operation and complex environmental conditions.

    Compact structure, easy integration

    The flat design of the Φ14×5 sensor allows for flexible placement within space-constrained energy storage monitoring modules. With the recommended external circuitry (500Ω/1kΩ/2kΩ load resistor), stable and reliable signal acquisition can be achieved, lowering the barrier to system integration.

    Selection Recommendations: Matching the Scenario, Balancing Performance and Cost

    For users in the energy storage field, it is recommended to select a model based on the actual application scenario:

    For cost-sensitive and relatively stable environments such as residential energy storage, small generators, and backup power supplies for communication base stations, the high cost-effectiveness of this sensor can be fully utilized;

    For scenarios with high requirements for reliability, response speed, and low-temperature adaptability, such as industrial and commercial energy storage cabinets and vehicle-mounted mobile energy storage systems, the technical specifications of the MQ2-CO-Φ14×5 can also fully meet these requirements;

    If long-term operation is required and maintenance is limited, it is recommended to manage spare parts in accordance with the sensor's short-circuit storage specifications to ensure optimal operating condition upon initial power-on.

    Energy storage safety is a systematic project, and gas sensing is the most intuitive and forward-looking part of it. Tensensor's MQ2-CO-Φ14×5 carbon monoxide sensor, based on electrochemical technology, has found a highly practical balance between accuracy, lifespan, and stability. It is not only a gas-sensitive element, but also a silent yet indispensable "olfactory defense" in the energy storage system.
