1. GENERAL
This manual forms part of the scope of supply and serves to ensure proper handling and optimum functioning of the instrument.
Consequently, it is essential to read the manual before commissioning.
The manual is also to be brought to the attention of any person involved in transport, setup,
operation, maintenance or repair.
This manual must not be used for competition purposes without the written consent of
E+E Elektronik® and must not be forwarded to third parties.
Copies for personal use are permitted.
All information, technical data and illustrations contained in this manual are based on the information available at the time of publication.
1.1 Symbol assertion
This symbol indicates a safety instruction.
Safety instructions must always be followed. Failure to do so can result in injuries or
damage, for which E+E Elektronik® accepts no liability.
This symbol indicates a note.
These notes should be observed to achieve optimum functioning of the equipment.
1.2 Safety instructions
•
Excessive mechanical stress and improper use must be avoided.
• As the sensor element is sensitive to electrostatic discharge (ESD), appropriate
protective measures should be taken when touching it.
• Installation, electrical connection, maintenance and commissioning must only be
carried out by qualified personnel.
1.3 Environmental information
E+E Elektronik® products are developed with due consideration to all major environmental issues. Bearing this in mind, care should also be taken to avoid polluting the environment when
disposing of equipment. When disposing of the transmitter, the individual
components must be sorted according to type.
Electronic components must be kept together and disposed of in the proper manner for electronic scrap.

2. PRODUCT DESCRIPTION
The EE75 series velocity transmitters were developed to obtain accurate measuring results over
a wide range of velocities and temperatures.
They have a robust metal housing to protect them against possible damage in rough
industrial environments and come in four different models, providing a comprehensive range of
mounting options:
• Model A for wall mounting
• Model B for duct mounting
• Model C with remote probe
• Model E with remote probe, pressure-tight to 10 bar (145psi)

3. INSTALLATION
Before starting the installation please make sure that the upper and lower
modules of the housings are not mixed up! Only with identical serial
numbers the function of the transmitter can be guaranteed within the
specifications (see chapter 9. “Technical Data”).

1. On delivery, the two mounting brackets (on the left and right of the
housing base plate) are attached to the lower part of the housing with
two screws each, facing inwards. For installation, the brackets can be
swung out and screwed down (see drawing).
2. The dimensions of the mounting holes are as shown in the adjacent
drawing.
3. The bottom part of the housing is fitted using 4 screws (not included).
Max. screw diameter 4.5 mm

See Section 3.1 - Installation of the housing
OR:
3.3.2 Mounting with a flange
The stainless steel mounting flange allows for the transmitter to
be mounted on the outside wall of the duct in which the
measurement takes place and adjusted to any insertion depth.

General safety instructions for installation using pressuretight movable screw connections
As the sensing probe can be exposed to very high pressures in the
measuring environment, there is a risk of sudden, unintentional expulsion of the probe during or after improper installation. Special care
should therefore be taken when working on or in the vicinity of the
sensing probe. Do not, under any circumstances, bend directly over the
probe.
When installing the sensor probe, be careful not to damage the surface
of the sensing probe.
This could damage the seals (resulting in leakage and pressure loss)
or cause problems when removing the probe (may get stuck).
Before installing the sensing probe, make sure it is free from any impurities such as grease or dirt.

Installing the probe
There should be a shut-off valve on both sides of the probe insert when
installing the probe. This makes it easy to remove the transmitter for
maintenance and calibration.
1. Install the probe with the shut-off valves closed.
2. Insert the sensor probe into the process.
3. To ensure the probe is installed securely, the lock nut must be
tightened to a specified torque of 10 Nm.
If no torque spanner is available, tighten the lock nut by hand as far
as possible and then turn it a further ~ 90° with an appropriate
open-ended spanner.
An inadequate torque results in a low tension force (fixing
force) on the clamping sleeve. This brings with it a risk of injury
due to sudden expulsion of the sensing probe. An excessive
torque can lead to permanent deformation of the clamping
sleeve and sensing probe, making removal and re-installation
more difficult or even impossible.
Removing the probe
1. If the sensor probe is installed in a pressure chamber, make sure
that the pressure in the chamber and the ambient pressure are
in equilibrium before removing the probe.
2. Hold the sensing probe/housing firmly. (Attention: Do not bend the
connection cable)
3. Slowly loosen the lock nut using a spanner (spanner width 24).
4. The entire probe can now be removed.

General installation instructions:
Scaling the insertion depth on the probe
The insertion depth can be read off directly on the probe. The depth is
measured from the centre of the velocity measuring slot (= middle of
x
scale
the sensor). The scaling on the probe has an offset of 30mm (1.2”). This
allows for the insertion depth "X" (= distance between middle of sensor
and mounting plate) to be read off directly above the screwed cable
gland (see sketch).
Flow direction
Flow direction:
The arrow on the sensor probe should be pointing exactly in the
direction of flow!
indicates the orientation of the tip of the arrow.
indicates the orientation of the tail of the arrow.
Model A (wall mounting):
indicates the orientation of the tip of the arrow.
Models B (duct mounting):
Models C and E (remote probe):
To be able to read off the orientation of the remote sensor head beyond
the measuring line, a mark has been punched at the end of the
sensing probe. This corresponds with:
