EE660 employs E+E air flow sensors manufactured in thin film technology. Sensing element operates on the hot film anemometer principle, which stands for excellent accuracy and long-term stability down to 0.15 m/s (30 ft/min), high insensitivity to pollution and low angular dependency.
EE660 Sensor for Very Low Air Velocity
The air velocity measured data is available as current and voltage outputs, on the RS485 interface with Modbus RTU or BACnet protocol, as well as on the optional display. EE660 is user configurable and adjustable with jumpers on the electronics board or via software. An optional configuration adapter and the free PCS10 Product Configuration Software facilitate the adjustment of EE660 and the display setup.
Typical Applications:
- Special ventilation applications
- Laminar flow control
- Clean rooms
