The EE660 from E+E Elektronik measures accurately very low air velocity. It is ideal for laminar flow monitoring and clean room applications. The transmitter is now also available with an RS485 interface.

The EE660 is suitable for accurate measurement of very low air velocity down to 0.15 m/s (30 ft/min). It features an E+E hot film sensing element, which offers excellent long-term stability and short response time. Furthermore, the sensing element is highly resistant to contamination and has a low angular dependency.

Additionally to current and voltage outputs, the device now features an RS485 interface with Modbus RTU or BACnet MS/TP protocol, which allows for easy integration into a bus system.

The EE660 is available for duct mount or with remote probe. The enclosure with external mounting holes facilitates installation with closed cover.

The measured data is also available on the optional display. Backlight and 180° rotatability allow for comfortable reading independent of the mounting conditions.

The EE660 is user configurable with jumpers on the electronics board or via software. The adjustment and the display setup can be performed with an optional configuration adapter and the free EE-PCS Product Configuration Software.
