The EE650 air flow transmitter from E+E Elektronik is dedicated for building automation and process control. The highly accurate device allows for reliable control of the air velocity in ventilation ducts and air conditioning systems. Besides the version with analogue output, the transmitter offers now RS485 interface and Modbus or BACnet protocol.

The EE650, available for duct mount as well as with remote sensing probe, measures air velocity up to 20 m/s (4000 ft/min). The new version features RS485 interface with Modbus RTU or BACnet MS/TP protocol, which facilitates the integration into a bus system. The EE650 with analogue output provides the measured data either as current or voltage signal. The measuring range, the output signal and the response time are user selectable.

Robust, Pollution-Resistant Sensing Element

The E+E air flow sensing element employed in EE650 operates on the hot-film anemometer principle. State-of-the-art transfer molding technology gives the thin-film sensor a high mechanical stability. Due to its innovative flow profile, the sensing element is particularly resistant to contamination, which leads to excellent measurement accuracy and long-term stability.

Easy Installation and Adjustment

The functional IP65 / NEMA 4 enclosure and the mounting flange included in the scope of supply facilitate the installation of the transmitter.

With an optional adapter cable and the free EE-PCS product configuration software, the user can adjust the EE650, set the output scale and select the interface parameters.
