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.
0.5... 5m/s: ±(0.2m/s (40ft/min) +3% of MV)

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.

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.
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.
