The EE650 air velocity transmitter is dedicated for accurate and reliable measurement in building automation and ventilation applications.  EE650 employs the new VTQ air velocity sensor element, which operates on the thermal anemometer principle and is manufactured by E+E in state-of-the-art thin fi lm technology. Due to its innovative design, the VTQ sensor element is very robust and highly insensitive to pollution, which leads to outstanding long-term performance. 

The measuring range 0-10/15/20 m/s (0-2000/3000/4000 ft/min), the output signal 4-20 mA or 0-10 V as well as the response time 1 or 4 seconds are selectable by jumpers. The enclosure design and the mounting fl ange included in the scope of supply allow for easy installation or replacement. EE650 can be adjusted by the user via digital interface.
