The E+E EE660 air velocity transmitter is engineered for highly accurate measurement of very low air velocities, making it the ideal solution for laminar flow control, clean rooms, and demanding ventilation applications. Its advanced hot film anemometer sensor provides excellent accuracy down to 0.15 m/s (30 ft/min) while offering high insensitivity to pollution, ensuring long-term reliability in critical environments.

The transmitter features three selectable measuring ranges (0–1 m/s, 0–1.5 m/s, and 0–2 m/s) via an internal jumper, allowing flexible adaptation to different application requirements. The response time can also be adjusted. Measured data is available on simultaneous 0–10 V and 4–20 mA outputs, simplifying integration with building management systems, PLCs, or data loggers. An optional RS485 interface and a backlit LCD display are available for enhanced connectivity and local readout.

Designed for easy installation, the EE660 includes a mounting flange and exhibits low angular dependence, minimizing installation errors. The M16x1.5 cable gland ensures secure wiring. Powered by 24 VAC/DC, the transmitter is suitable for a wide range of industrial and HVAC applications.

Typical applications include:

• Clean room air velocity monitoring
• Laminar flow cabinet certification
• HVAC system balancing and validation
• Pharmaceutical and semiconductor manufacturing environments
