ee650 - air velocity Transmitter for hvac applications

GENERAL

The EE650 transmitter is designed for accurate measurement of air velocity in HVAC. It operates on the hot-film anemometer prin-
ciple and features the innovative, very robust E+E VTQ sensing element manufactured in thin-film technology combined with state-
of-the-art transfer molding.
The construction of the sensing head leads to a very low angular dependence which facilitate the installation. The mounting flange
allows for easy adjustment of the immersion depth.
The measuring range and the response time of EE650 can be selected with jumpers on the electronics board, see below

"Settings".

EE650 is dedicated for heating, ventilation and air conditioning 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 sensing 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 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.
SETTINGS
For performing EE650 settings via EE-PCS Product Configuration Software (download from www.epluse.com/configurator) the
working range jumper must be on HI.

  • Page 4 PosiTioninG of aiR velociTy sensoR in a venTilaTion DucT The reliable and accurate measurement of air velocity depends on the correct positioning of the sensor in the ventilation duct. Accurate measurements are only possible if the air velocity probe is positioned at a location with a laminar (to-turbulent) flow. The required length of the calming section after a fault is a function of the tube diameter D.
