E+E Elektronik EE650 Manuale utente

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.

CONFIGURATION AND ADJUSTMENT

The EE650 as ordered is ready for use immediately and requires no configuration by the user. If required, the optional E+E Product

Configuration Adapter (EE-PCA) and the E+E Product Configuration Software (EE-PCS) can be used for changing the factory

setup as well as for adjusting of the air velocity measurement. Additionally, it allows for setting the display backlighting and

orientation.

The arrow engraved on the sensing head of EE650 indicates the direction of the air stream during factory adjustment. When

installing the EE650 probe, make sure that the arrow matches exactly the flow direction.

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. For a rectangular channel a x b applies:

<6D

>3D

>6D

Mounting the sensing probe in the middle of the

channel.

The optimal position is after the filter.

Please note sufficient distance.

Positioning the probe ahead of diffusor, at a place

with high flow rate.

Positioning the probe at a location with a laminar (to-

turbulent) flow.

Turbulent flows are caused by pipe bends, branches,

behind flaps, flans, air heaters, air coolers or cross-

sectional changes.

MAINTENANCE OF THE E+E AIR VELOCITY TRANSMITTERS

Due to the absence of moving parts, the E+E air velocity transmitters are not subject to wear. The construction (shape, dimensions

and materials) of the hot film air velocity sensor is per se highly insensitive to dust and dirt. No maintenance is required under

normal environmental conditions. For operation in polluted environment it is advisable to periodically clean the sensing head by

washing it in isopropyl alcohol, preferably in an ultrasound cleaner. Alternatively shake it gently few minutes in a pot with isopropyl

alcohol and let it dry free. Do not touch or rub the sensor and do not use any mechanical tools for cleaning.
