E+E Elektronik EE671 User Manual

USER MANUAL
EE671 - Miniature Air Flow Probe
GENERAL
The EE671 air velocity sensor operates on the hot-film anemometer principle and features an innovative, very robust E+E
sensing element manufactured in thin-film technology combined with innovative transfer-molding.
The mounting flange allows for correct positioning and easy adjustment of the immersion depth.
EE671 is dedicated for accurate and reliable measurement in building automation and ventilation applications. For special
applications do not hesitate to contact the manufacturer or their local distributor.
CAUTION
• Accurate measurement results are conditioned by the correct positioning of the probe in the air stream. Best accuracy is
achieved in laminar flow.
• Observe the minimum inlet and outlet path length, see page 4.
• Avoid mechanical stress on the probe and especially 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.
ELECTRICAL CONNECTION
Important note:
The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling,
installation, wiring, power supply and maintenance of the device.
Please note:
The device may only be powered with a power supply class III
ƒ
EE671 is an ESD-sensitive device. It is neither short-circuit-proof, nor surge-proof. The digital communication lines
