USER‘s guide EE660 - Transmitter for Very Low Air Velocity GENERAL The EE660 transmitters are designed for the exact measurement of air velocity. The measuring method is based on the hot film anemometer principle. The special construction of the sensor mounting provides a very small directional derivate within a wide range, thus allows easy mounting. Using the mounting device the penetration depth is infinitely adjustable. By changing a jumper on the PCB the measuring range and the response time can be set. The transmitters are designed for applications within the HVAC industry, in clean room applications and laminar flow control. For special applications do not hesitate to contact the manufacturer or the corresponding distributor.
CAUTION • The accurate and reliable determination of the air velocity depends on the correct positioning of the probe. Accurate measurements are only possible if the probe is installed in a location with approximate laminar flow. • For duct mounting the required inlet and outlet paths have to be observed. More information can be found on www.epluse.com. • Extreme mechanical, unspecified strain, corrosive environments and condensation must be avoided.

SETUP AND ADJUSTMENT The EE660 is ready for use immediately and requires no configuration set-up by the customer. If required, the optional E+E Product Configuration Adapter (EE-PCA) and the E+E Product Configuration Software (EE-PCS) can be used for customer adjustment of the air velocity. Various display settings such as backlighting and orientation can also be changed.

Immersion depth = 30% - 50% of the pipe diameter pipe diameter
The mounting flange allows for an infinite variation of the depth of the sensor probe. It is important to ensure that the sensor head is completely submerged into the flow.
Air Velocity
If the sensor probe is installed without a mounting flange, make sure the air velocity sensor is aligned parallel with the air stream.
