EE671 HVAC Miniature Air Flow Probe
  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.
Type EE671 air velocity sensor cable version
  EE671 air velocity sensor plug version
Detail 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
Key Features EE671 High accuracy and long-term stability
  Outstanding resistance to contamination
  Easy and quick mounting
  User configurable
