Description

Air velocity transmitter

      E+E 671 operates on the hot-film anemometer principle and ensures high accuracy as well as long-term stability and outstanding resistance to pollutants. 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 reproducible 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 as linear voltage output 0 – 1 V, 0 – 5 V or 0 – 10 V. The alignment strip on the probe and the matching mounting flange within the scope of supply simplify installation and correct positioning in the air flow. The flange enables the immersion depth to be infinitely variable.
With an optional configuration kit the user can set via a digital setup interface the output configuration and perform an adjustment of the probe.
