In today's era, characterized by a strong emphasis on low-carbon environmental protection, novel refrigerants—such as R290—are emerging as the "new favorites" of the air conditioning and refrigeration industry, thanks to their superior thermodynamic properties and extremely low Global Warming Potential (GWP). However, as these refrigerants are typically flammable, they impose stringent requirements on the real-time responsiveness and reliability of leak detection systems. Leveraging advanced semiconductor fabrication processes and a superior anti-interference design, Tensensor's TX210-Q211 planar refrigerant detection module is establishing itself as the core guardian of safety within refrigeration systems.

TX210-Q211 Refrigerant gas detection module

    Technical Core: A Revolution in Sensitivity via Multi-Layer Thick-Film Technology

    The heart of the TX210-Q211 module lies in its semiconductor gas-sensing element, which utilizes an advanced multi-layer thick-film manufacturing process. This precision engineering not only miniaturizes the sensor but also delivers a qualitative leap in performance:

    **A Filtering Layer Engineered to Eliminate "False Signals":** The gas-sensing element features a built-in, specialized filtration and adsorption layer capable of significantly mitigating cross-interference from common gases such as alcohol. In complex domestic or industrial environments, it precisely identifies refrigerant molecules, thereby effectively reducing the rate of false alarms.

    **Rapid Response and Recovery:** Designed to address the sudden nature of refrigerant leaks, the module achieves an exceptionally fast response speed (with a recovery time of less than 120 seconds), ensuring that potential risks are detected and pinpointed the moment they emerge.

    **Factory-Calibrated "Plug-and-Play" Experience:** Prior to shipment, every module undergoes rigorous aging, calibration, and validation procedures to ensure exceptional consistency. Developers can directly access accurate concentration readings via PWM signals without the need for additional field adjustments.

    Core Parameters: Stable and Reliable Industrial-Grade Performance

    **Precise Alarm Threshold:** The alarm concentration is set at 2000 ppm, providing critical early warning before refrigerant levels reach a potentially hazardous threshold.

    **Wide Environmental Adaptability:** Capable of stable operation in environments ranging from -20°C to 55°C, the module effortlessly accommodates the diverse temperature conditions found in residential air conditioning, commercial cold storage facilities, and automotive HVAC systems.

    **Intelligent Diagnostics:** Features a built-in self-diagnostic function for sensor faults, ensuring the system remains under constant supervision and preventing monitoring gaps caused by sensor failure.

    Enabling Diverse Application Scenarios

    1. Smart Residential Air Conditioning and Heat Pump Systems

    With the growing adoption of R290 refrigerant in residential air conditioning, the TX210-Q211 can be seamlessly integrated into the base of the indoor unit or within the compressor compartment of the outdoor unit. Upon detecting even trace amounts of leakage, the module triggers the main control board to immediately cut power to the compressor and initiate forced ventilation, thereby nipping safety risks in the bud.

    2. Commercial Cold Chain and Cold Storage Safety

    In large-scale cold storage facilities or commercial refrigeration units, a leak represents not only a safety hazard but also a source of substantial maintenance costs. The compact dimensions of the TX210-Q211 (25 × 34 mm) allow for flexible deployment at common leak points—such as pipe joints—enabling long-term, stable, and continuous online monitoring.

    3. Automotive Air Conditioning System Monitoring

    In vehicle-mounted air conditioning systems, this module serves as a core sensing unit, providing real-time monitoring of the airtightness within both the cabin and the AC refrigerant lines. This capability provides critical data support for the comprehensive thermal management systems found in new energy vehicles.

    TX210-Q211 Planar Refrigerant Detection Module is far more than just a hardware component; it represents Tensensor’s expert response to the critical safety imperatives emerging within the trend toward eco-friendly refrigeration. By seamlessly integrating high sensitivity with exceptional stability, it empowers manufacturers of refrigeration equipment to construct an impenetrable safety barrier—enabling them to pursue high efficiency and environmental sustainability without ever compromising on safety.
