EE576

Miniature air flow sensor for measurement of minimal flows.

Questions about our products?

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 velocity 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...2m/s (0...400ft/min) or 0...1m/s (0...200ft/min).

FAQ

  • How can I clean the air velocity sensing element?

    Due to its design and materials, the E+E thin film sensing element for air velocity is highly insensitive to pollution. When operaten in very dusty or diry environment, cleaning might be necessary. See section maintenance at downloads.epluse.com/fileadmin/data/miscellaneous/datasheet_air_velocity_measurement_basics.pdf

  • How can I replace the air velocity sensing element or the air velocity sensing probe?

    This is not possible. Return the device to E+E for service.

  • What kind of calibration certificate is included in the standard scope of supply of the E+E air velocity sensors?

    The standard scope of supply of E+E air velocity sensors includes an inspection certificate according DIN EN 10204 - 2.2 or DIN EN 10204 - 3.1, depending on the model. Please see the product data sheet and operation manual for the type of certificate. For details on calibration certificates please see page 5 in www.kalibrierdienst.at/fileadmin/content/White_Paper_Calibration_and_traceability_in_measuring_technology.pdf

  • Can E+E supply an accredited calibration certificate with the air velocity sensor?

    Accredited calibration certificate for air velocity is available upon request, please see our calibration website. 

  • What is the difference between a 2 wire and a 3 wire current output?

    Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
