Air Velocity and Temperature Sensor for Laminar Flow
Flow direction
For best measuring accuracy the sensing element of the EE680 must be aligned exactly in the direction
of the laminar flow in which factory adjustment took place.
An arrow symbol on the sensor tip indicates factory adjustment direction. The arrow on the sensor
probe should be pointing exactly in the direction of the laminar air flow.
The angular deviation must be kept to a minimum.

5 Setup and Configuration
The EE680 is ready to use and does not require any configuration by the user. The EE680 factory setup
corresponds to the type number ordered. Please refer to the data sheet at www.epluse.com/EE680. The
user can change the factory setup with the help of the EE-PCS Product Configuration Software and the
Modbus configuration adapter (order code HA011018).
Besides the measurand selection of the analogue and digital outputs and their scaling, the digital
interface settings may be changed. The RH and T measurement is offset and 2-point adjustable. It is
possible to enable or disable the optical status indication and the NAMUR error indication (factory setting:
disabled). Temperature and barometric pressure reference values for standardized air velocity calculation
can be set.
Please note:
The EE680 may not be connected to any additional power supply when using the Modbus
configuration adapter HA011018.
