SCOPE OF SUPPLY
•
EE660 Low Air Velocity Sensor
•
Cable gland (two pieces at output RS485 for daisy chain wiring)
•
Mounting flange
•
Mounting materials
•
Protection cap
•
Quick guide
•
Two self-adhesive labels for configuration changes (see user guide at www.epluse.com/relabeling)
•
Test report according to DIN EN10204 - 2.2
CAUTION
• Accurate measurement results are conditioned by the correct positioning of the sensing probe in the air stream. Best accuracy
is achieved in laminar flow.
• Observe the minimum inlet and outlet p
ath length, see page 5.
• Avoid mechanical stress onto the probe and mainly onto the sensing head.
• Observe the humidity working range 5…95% RH, non-condensing.
• Avoid installation in corrosive environment, as this may lead to sensor destruction.
