Sensor for Very Low Air Velocity

EE660

The EE660 air velocity sensor operates on the hot film anemometer principle and is optimised for precise measurement of very low air velocity in laminar flow monitoring and clean room applications.

EE660 air flow sensor with remote probe and display

EE660 employs E+E air flow sensors manufactured in thin film technology, which stands for excellent accuracy and long-term stability down to 0.15 m/s (30 ft/min).
The device is available with current and voltage output or with RS485 interface an Modbus RTU or BACnet MS/TP interface. EE660 is user configurable and adjustable with jumpers on the electronics board or with the EE-PCS Product Configuration Software.
