  • Clean room compatible design following GMP standards
  • Stainless steel probe and sensing head
  • Sensing element with E+E proprietary Coating
  • Measurement range down to 0.1 m/s (20 ft/min)
  • Combined air velocity and temperature measurement
  • LED ring for condition visualization
  • Modbus RTU or analogue outputs
  • User configurable and adjustable

Technical data

  • 0…2 m/s (0…400 ft/min MEASURING RANGE – AIR VELOCITY)
  • 0.1…2 m/s (20…400 ft/min): ± (0.5 % of mv* + 0.05 m/s) ACCURACY – AIR VELOCITY * MV – MEASURED VALUE
  • -20…70 °C (-4…158 °F) MEASURING RANGE – TEMPERATURE
  • ±0.5 °C (±0.9 °F) ACCURACY – TEMPERATURE
  • 0-5 V / 0-10 V or 0-20 mA / 4-20 mA (3-wire) ANALOG OUTPUTS

Outstanding Measurement Performance
The EE680 operates on the hot film anemometer principle. It employs an E+E thin film sensing element which stands for excellent accuracy down to 0.1 m/s (20 ft/min), outstanding long term stability and low angular dependency. The multipoint air velocity factory adjustment leads to best performance over the entire working range. The E+E proprietary coating protects the sensing element against H2O2 and corrosive cleaning agents.

The EE680 is available as straight and angled version with various probe lengths and is optimized for easy cleaning. The mounting concept and the M12 stainless steel connector facilitate the easy installation or replacement of the sensor. A led ring integrated in the stainless steel enclosure shows the laminar flow conditions and the sensor status.

Analogue and Digital Outputs
The air velocity and temperature measured data is available as current or voltage analogue outputs or on the RS485 interface with Modbus RTU protocol, user selectable.

Configurable and Adjustable
The setup and adjustment of the EE680 can be easily performed with an optional adapter and the free PCS10 Product Configuration Software.
