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.

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.
