Datasheet

The EE576 is a compact air velocity transmitter designed for
measurement of lowest velocity. Equipped with a newly
developed sensor head and utilizing the proven E+E hot-film
element, already tested a million times in the automotive
industry, these transmitters are less sensitive to dust and dirt
than conventional hot-wire elements. This is reflected in the
excellent reproducibility and proven long-term stability of the
measuring results.
The factory calibration with a special wind tunnel for lowest velo-
city ensures optimal precision and maximum sensitivity.
The EE576 can be mounted fast and easily.
The alignment strip along the probe’s tube and the matching mounting flange determine the orientation of
the sensor probe. The mounting flange allows for an infinitely variation of the depth of the sensor probe.
The electronics integrated in the probe tube provide a linear analogue signal of 0-5V or 0-10V for
the velocity range 0...1m/s (0...200ft/min) or 0...2m/s (0...400ft/min).
