The high-end air velocity sensor element operates on the hot film anemometer principle and which stands out by high sensitivity even at very low air speed and high insensvity to pollution. T
he robust sensing probe and enclosure allow for EE75 use in harsh industrial environment as well as in applications with pressure rating up to 10 bar (145 psi).
Beside measuring air velocity and temperature, EE75 calculates the volumetric flow rate in m³/h or ft³/min based on the cross section of the duct, with an appropriate factory correction. The EE75 can be used to measure the velocity of various non-flammable and non-corrosive gases.

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
This is not possible. Return the device to E+E for service.
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
Accredited calibration certificate for air velocity is available upon request, please see our calibration website.
For readjusting the air velocity sensor you need first of all a reliable reference. This would be a wind channel. For the readjustment procedure please see the operation manual of the specific E+E air velocity sensor available at www.epluse.com
In case an approriate air velocity reference in not available, please return the device to E+E for service.
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.
