  • Air flow
  • Sigma 05


EE671 is a compact air velocity probe for HVAC applications. The built-in flow sensing element VTQ combines the advantages of state-of-the-art E+E thin-film manufacturing and of the newest transfer molding technology.

  • EE671 air velocity sensor plug version

  • Sigma 05 with air velocity sensor EE671

    It operates on the hot-film anemometer principle and ensures high accuracy and reproducibility as well as long-term stability and outstanding resistance to pollutants.

    EE671 is available with fix installed cable or with plug connection. The measured air velocity up to 20 m/s (4000 ft/min) is available at voltage output 0 - 1 V, 0 - 5 V or 0 - 10 V or on the Modbus RTU interface.

    The alignment nut on the probe and the matching mounting flange simplify the installation, the correct orientation in the air flow and the precise control of the immersion depth.

    With an optional configuration kit the user can set via a digital setup interface the output configuration and perform an adjustment of the probe.

    Typical Applications

    • Heating and ventilation systems
    • Flow monitoring and control
    • Inlet air monitoring in ovens

    Sigma 05 - Modular Sensor Platform

    The EE671 is compatible with the Sigma 05 host device of the E+E Modular Sensor Platform. Together they become a versatile, plugand-play RH / T modular sensor with analogue outputs and optional display. Besides EE072, Sigma 05 accommodates also other E+E intelligent sensing probes.
