EE680 Air Velocity Sensor for Laminar Flow Monitoring
  The EE680 is dedicated for precise measurement of the air velocity and monitoring the temperature in laminar flow. The GMP compliant design is ideal for cleanrooms and safety cabinets in pharmaceutical, life sciences and microelectronics industries.
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.
Versatility 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 EE-PCS Product Configuration Software.
