Sensor for Very Low Air Velocity

Open Link in Lightbox
  • Air flow


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 velocity sensor for duct mounting

  • EE660 air velocity 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.


    • Accurate measurement down to 0.15 m/s (30 ft/min)
    • Excellent long term stability
    • High resistance to pollution
    • Small angle dependency
    • Large, easily readable display
    • Current and voltage output
    • Modbus RTU or BACnet MS/TP
    • User configurable and adjustable

    Foire Aux Questions (FAQ)

    Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
