    TB420 4-20mA Gas Sensor Module For Gas Detection In Indoor Outdoor Environments


    TB420 4-20mA Gas Sensor Module


    Overview:


    TB420 is an intelligent two-wire 4-20mA gas sensor module from German manufacturer EC Sense. It adopts high-reliability solid polymer electrochemical gas detection technology and intelligent algorithm design, complying with industry standards for gas safety monitoring.


    Technical Parameters:

    1. Detection Principle:Solid polymer electrochemical
    2. Output Signal Interface:Two-wire 4-20mA (convertible to 40-200mV via external resistor)
    3. Operating Voltage:9-24V DC
    4. Current Consumption:3-22mA@24V DC
    5. Power Consumption:<0.6W
    6. Maximum Loop Resistance:<500Ω@24V DC
    7. Protection:Reverse polarity protection
    8. Operating Temperature:-40°C to +55°C
    9. Operating Humidity:15-95%RH (non-condensing)
    10. Pressure Range:Atmospheric pressure ±10%
    11. Storage Temperature:0°C to 20°C
    12. Dimensions (with sensor):45x35x11.9mm
    13. Dimensions (without sensor):45x35x11.9mm
    14. Weight (with sensor):7.8g
    15. Weight (without sensor):7.1g
    16. Packaging:ESD BAG (120x150mm)

    Functional Features:

    1. Factory Pre-calibration:Gas-calibrated at the factory, with calibration data stored in Flash memory. Users can use it directly or perform secondary calibration via EC Sense's calibration software, or calibrate 4-20mA signals directly.
    2. Sensor Health Monitoring:Outputs sensor performance and lifespan indicators, as well as fault signals. Regularly provides real-time health status (normal operation, failure, maintenance needed, replacement required) with or without the target gas.
    3. High Performance:Fast gas response, stable zero point without drift, strong EMI resistance, long-life gas sensor with anti-poisoning capability.
    4. Environmental Protection:PCB coated with dust-proof and corrosion-resistant layers.
    5. Development Efficiency:Shortens development time for gas monitoring instruments, reduces design costs and risks, accelerates production cycles by eliminating complex gas calibration processes, and improves instrument reliability and accuracy.
    6. Industrial Compatibility:Standard 4-20mA industrial signal mode enables quick integration into monitoring systems, display meters, DCS, PLC, etc.

    Application Fields:

    Suitable for indoor and outdoor gas detection, including:


    • Industrial gas safety monitoring
    • Air quality monitoring
    • Industrial process gas monitoring
    • Semiconductor gas purification monitoring
      Provides real-time dynamic data for ambient gas detection.
