Air Velocity Sensor for Laminar Flow Monitoring
The EE680 by E+E Elektronik offers high measurement accuracy and is ideal for cleanroom applications due to its GMP-compliant design
The flow sensing element used in the EE680 is based on the hot film anemometer principle and enables simultaneous measurement of air velocity and temperature. It provides accurate values from as low as 0.1 m/s (20 ft/min) and offers excellent long term stability and low angular dependence. The special E+E sensor coating makes the thin film sensing element highly resistant to H2O2 sterilisation and other aggressive cleaning agents.
High Measurement Accuracy
Factory multi-point adjustment of the air velocity ensures high measurement accuracy over the entire working range. An adjustment point at 0.45 m/s (88.6 ft/min) takes into account the air flow range defined in the EU GMP directive for the manufacture of sterile medical devices. The measurement accuracy of the sensor is confirmed by an inspection certificate in accordance with DIN EN 10204-3.1.
With its smooth stainless steel enclosure and a sensor design optimised for laminar flow monitoring, the EE680 meets the requirements of Good Manufacturing Practice (GMP) in the cleanroom. The straight or angled design of the sensor with different probe lengths allows for wall or ceiling mounting at the ideal distance from the filter element, according to EN ISO 14644-3. The practical mounting flange and M12 stainless steel connector facilitate the installation and replacement of the EE680.
Visual Status Indication
An LED ring integrated into the enclosure indicates the laminar flow conditions and the sensor status. Any deviation from the target state or operating fault can therefore be quickly detected. The preset threshold values and further indication options can be configured individually.
Analogue or Digital Output
The measured values for air velocity and temperature are optionally available at the analogue voltage or current output, or at the RS485 interface via the Modbus RTU protocol. The type of measured value output can also be retroactively configured.
Configuring and adjusting the EE680 is a particularly user-friendly experience with the help of an optional adapter and the free configuration software.
