EE650
The EE650 air velocity transmitter is dedicated for accurate and reliable
measurement in building automation and ventilation applications.
The device employs an innovative air velocity sensing element, which
operates on the thermal anemometer principle and is manufactured by
E+E in state-of-the-art thin lm technology. Due to its innovative design,
the sensing element is very robust and highly insensitive to pollution,
which leads to outstanding long-term performance.
For the EE650 with analogue output, 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 bus address, the termination resistor and the response time of the
Modbus RTU and BACnet MS/TP versions can also be easily set on the
electronics board.
The enclosure design and the mounting ange included in the scope of
supply allow for fast and easy installation.
With an optional adapter cable and the free EE-PCS product conguration
software, the user can adjust the EE650, set the output scale and select
the interface parameters.
