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 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.

Air Flow Sensor for HVAC
Accurate and reliable measurement up to 20m/s (4000 ft/min). Very robust and highly insensitive to pollution. Analogue output or RS485 interface with Modbus or BACnet protocol.
High accuracy air flow sensor for industrial applications.
High accuracy measurement of flow and temperature in industrial processes up to 10 bar and 120°C. Also ideal as a reference unit for labs and test rigs.
Miniature air flow sensor for measurement of minimal flows.
Excellent accuracy down to 0.2 m/s (40 ft/min). Voltage output. Optimized for clean rooms and laminar flow monitoring.
Monitoring of laminar air flow cabinets
Laminar flow cabinets are used as local clean rooms for the production, assembly and testing of sophisticated products with high quality standards. The directed, turbulence-free air flow reduces the suspension of existing particles and removes them with the downwardly directed air flow
