E+E Elektronik EE660 User Manual

USERʼS GUIDE
EE660 - Low Air Velocity Sensor
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
• 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.
