The EE650 air flow sensor is dedicated for accurate and reliable measurement in building automation and ventilation applications.

EE650 employs the new VTQ air flow sensor element, which operates on the thermal anemometer principle and is manufactured by E+E in state-of-the-art thin film technology.

Due to its innovative design, the VTQ air flow sensor element is very robust and highly insensitive to pollution, which leads to outstanding long-term performance. 

The measured data is available either on an analogue voltage or current output, user selectable, or on the RS485 interface with Modbus RTU or BACnet MS/TP protocol.

The enclosure design and the mounting flange included in the scope of supply allow for easy installation or replacement. The configuration and adjustment of the EE650 can be comfortably performed on the electronics board or via digital interface.
