2. Product Description
The EE75 velocity sensors were developed to obtain accurate measuring results over a wide range of velocities and temperatures.
They have a robust metal enclosure to protect them against possible damage in rough industrial environments and come in three different typs, providing a comprehensive range of mounting options:
- Type T2 for duct mounting
- Type T3 with remote probe
- Type T26 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 enclosures are not mixed up! Only with identical serial numbers the function of the sensor can be guaranteed within the specifications (see chapter 9. “Technical Data”).
3.1 Installing the Enclosure
-
On delivery, the two mounting brackets (on the left and right of the enclosure base plate) are attached to the lower part of the enclosure with two screws each, facing inwards. For installation, the brackets can be swung out and screwed down (see drawing).
-
The dimensions of the mounting holes are as shown in the adjacent drawing.
-
The bottom part of the enclosure is fitted using 4 screws (not included).
Max. screw diameter 4.5 mm (0.18″), for example 4.2 x 38 mm (0.17 x 1.5″)
– DIN 7983H screws. -
Connecting the sensor (see chapter 4 – Electrical Connections)
-
Lift the upper part of the enclosure into position and screw it into place using the four Allen screws included (Allen key provided).
3.2 Mounting Type T2 (Duct Mounting)
There are two types of duct mounting:
3.2.1 Mounting with Brackets
Refer to chapter 3.1
OR:
3.2.2 Mounting with a Flange
The stainless steel mounting flange allows for the sensor to
be mounted on the outside wall of the duct in which the
measurement takes place and adjusted to any insertion depth.
3.3 Mounting Type T3 (Remote Probe)
3.3.1 Installing the enclosure
Refer to chapter 3.1
3.3.2 Installing the probe
Refer to chapter 3.2.2 – Mounting with a Flange
3.4 Mounting Type T26 (Remote Probe, Pressuretight
up to 10 bar / 145 psi)
3.4.1 Installing the Enclosure
Refer to chapter 3.1
3.4.2 Installing the Probe
General safety instructions for installation using pressure tight 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 sensor for maintenance
and calibration.
- Install the probe with the shut-off valves closed.
- Insert the sensor probe into the process.
- 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
- 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.
- Hold the sensing probe/enclosure firmly. (Attention: Do not bend the connection cable)
- Slowly loosen the lock nut using a spanner (spanner width 24).
- 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 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).

5.2 Jumpers for Setting the Output Signal
If the sensor output signal is set from current to voltage by use of the
configuration software, additionally 2 jumpers must be set on the circuit
board as follows:
5.3 Jumpers for Setting the Velocity Response Time
The EE75 allows users to set the velocity response time:
a) Setting the velocity response time using jumpers:
Jumper position (Also see chapter 5.1 – Circuit Board): Response time:
b) Setting the velocity response time using configuration software:
The response time (τ90) can also be set to any value between 1.5 and 40 s
using the configuration software, without changing the jumpers on the circuit
board. See Configuration Software, chapter 4.4 – Response Time
5.4 Display Module with Buttons (Optional)
4. MIN / MAX Function:
The MIN / MAX function can be used to record the lowest and highest values
measured for each measurand since the last reset or the last interruption of
the power supply.
By pressing the UP and DOWN buttons simultaneously in normal operating mode the stored MIN/MAX values for all measurands can be reset by selecting “CLEAR MIN/MAX BUFFER”; recording can then be restarted (for details see chapter 5.3 – Display Module with Buttons, point 7 – Menu navigation).
5. Measured Value:
The measured value of the respective measurand is indicated.
Pressing the UP and DOWN buttons moves the cursor “>” on the left-hand side of
the display up and down to select one of the adjacent menu items.
Pressing the UP and DOWN buttons simultaneously for approx. 5 s confirms the
selection and executes the selected menu item.
6. Velocity / Temperature Calibration
The EE75 can be calibrated / adjusted using either the buttons on the optional display module or the USB interface and configuration software provided.
Instructions for calibration:
To achieve comparable results to the E+E factory setting, please note
following:
a) The adjustment should be done in a wind tunnel with homogeneous, low
turbulent flow profile.
b) Insert the probe 10cm deep into the flow channel.
c) The fixtures should be mounted outside the flow channel and should not rise
into the air stream (see drawing):
6.1 Selecting the Appropriate Calibration Method
(1-point or 2-point Calibration)
The EE75 sensor can be calibrated in 2 different ways:
– 1-point v/T calibration:
Quick and easy option for obtaining precise measuring results at a specific
working point. 1-point calibration should only be used for very limited
working ranges.
– 2-point v/T calibration:
With 2-point calibration, precise measuring results can be obtained over the
entire v/T measuring range. The more complicated 2-point calibration procedure
is preferable to 1-point calibration, if higher precision or a wider working
range is required.
6.1.1 General Information on 1-point v/T Calibration:
If possible the selected calibration point should be similair to the working
point (of the limited working range) of the sensor.
Example: Working range v 8 – 12 m/s (1600 – 2400 ft/min) > calibration point
at 10 m/s (2000 ft/min); working range T 18 – 22 °C (64.4 – 71.6 °F) – >
calibration point at 20 °C (68 °F).
- If the selected calibration point is < 50 % of the max. measuring range, V/T-CAL LOW should be selected for calibration / adjustment.
- If the selected calibration point is > 50 % of the max. measuring range, V/T-CAL HIGH should be selected for calibration / adjustment.
Example: v measuring range 0 – 10 m/s (0 – 2000ft/min); actual working
range 6 – 8 m/s (1200 – 1600 ft/min);
selected calibration point 7 m/s (1400 ft/min); perform 1-point calibration,
selecting V-CAL HIGH.
6.1.2 General Information on 2-point v/T Calibration:
With 2-point calibration, v/T calibration / adjustment is performed at 2
different calibration points.
To ensure the smallest possible deviation in measuring results over the entire
measuring range, the two calibration points should be selected as follows:
-
The low calibration point should be in the lower third of the measuring range.
Calibration / adjustment must be performed using the V/T-CAL LOW function. -
The high calibration point should be in the upper third of the measuring range.
Calibration / adjustment must be performed using the V/T-CAL HIGH function.
Example: EE75 T3***HV23 – measuring range = 0 … 2 m/s (0 – 400 ft/min).
Low calibration point (V-CAL LOW) should be around 0.4 m/s (0…0.7).
High calibration point (V-CAL HIGH) should be around 1.8 m/s (1.4…2).

the velocity and temperature settings.
System requirements: Windows XP or higher, interface USB 1.1 or higher.
NOTE:
Any use beyond these purposes is not permitted.
The permanent connection between EE75 and PC via the USB interface in normal
operation may cause a malfunction and does not meet the CE-criteria.
2. Installation
NOTE:
Administrator authorisations may be required for problem-free installation of
the EE75 configuration software.
- During installation do NOT connect the EE75 to the PC using the USB Port.
- Run “Setup.exe” to install the EE75 configuration software.
- The InstallShield Wizard for the EE75 configurator is launched.
- Follow the instructions to install the software.
- Clicking the “Finish” button completes configuration software installation.
2.1 Installing the USB-Interface
NOTE:
The USB interface software must also be installled to allow your PC and the
EE75
velocity sensor to communicate properly.
- Connect terminals and USB-interface located in the back module of the EE75 enclosure under zero-potential conditions
- Replace and secure the upper module of the enclosure
- Connect EE75 to the supply voltage (VCC)
- You can now connect the EE75 to your chosen USB Port on your PC (max. transmission distance 3 m).
- The driver software will be installed automatically
If the EE75 configuration software and the associated USB interface have been set up correctly, a connection has been assigned to the EE75 USB to UART Bridge Controller on your PC’s Control Panel.
See Start / Settings / Control Panel / System / Hardware / Device Manager
6. The configuration software can now be opened by double-clicking the EE75
icon on your desktop.

3.2 Help
Provides general information on the configuration software.
4. EE75 Configurator
4.3 Display
With an optional display, the following can be set on the Display tab:
“Display Mode” drop-down input field:
– Single-line display
– Two-line display (factory setting)
“Backlight on” check box
– Activated = ON
– Not activated = OFF
4.4 Response Time
As described under Hardware, chapter 5.2 – Jumpers for Setting the Velocity Response Time, three different response times can be set.
Users can also assign a response time of between 1.5 and 40 s to each jumper position using the configuration software.
Example:
Jumper at position 1: changes from 2 s (factory setting) to 35 s.
The green pilot lamp next to the jumper position indicates which jumper
position is currently set and consequently active.
Note: If the response time of the jumper currently active is changed and uploaded using the “Write” function, the sensor’s velocity response is switched without changing the hardware (jumper position).
4.5 Cross Section
The EE75 allows volumetric flow to be displayed in [m³/min] or [ft³/min.] (see Hardware, chapter 5.3 – Display Module with Buttons – Measurands).
The volume is calculated based on the flow velocity measured and the cross section. Consequently, the cross sectional area of the duct must be entered in [m²] or [ft²].
To make it easier to calculate the cross sectional area, the “Cross sect.” tab provides input assistance:
Circular: Measure and enter the duct diameter in [m] or [ft] – Press
“calculate”
– The cross section is calculated and entered in the “Cross sectional area”
field
Rectangular: Measure and enter the duct length and width in [m] or [ft] –
Press “calculate”
– The cross section is calculated and entered in the “Cross sectional area”
field
If the duct has a different shape or the cross-sectional area is already
known, the value can, of course, also be entered directly in the “Cross
sectional area” field, in [m²] or [ft²].
4.6 Probe Cable
The length of the probe cable (sensor with remote probe) should not normally
be changed.
However, if it is necessary to do so, the new (modified) probe cable length
must be entered on the “Probe Cable” tab. This virtually rules out additional
measuring errors due to the modified cable length.
Example: You order an EE75 T3***K5 (5m / 16.4ft cable length) and then cut the
cable with 3m (9.8ft). The new cable length of 2m (6.6ft) should be entered
and uploaded using the “Write” function.
Notes:
– The cable length is measured from the centre of the sensor element in the
sensor head to the point where it enters the enclosure (PG / screw
connection).
– To increase the length of the probe cable, the instrument must be returned
to E+E Elektronik.
Velocity and temperature calibration is not only possible using the buttons on the integrated display, the EE75 can also easily be calibrated / adjusted using the configuration software.
Note:
The configuration software automatically distinguishes between the low and
high calibration points.
– If the selected calibration point is BELOW the centre of the measuring
range, it is automatically recognised as the “low calibration point” (CAL
LOW).
– If the selected calibration point is ABOVE the centre of the measuring
range, it is automatically recognised as the “high calibration point” (CAL
HIGH).
4.9.1 Information on 1-point v/T Calibration
If possible the selected calibration point should be similair to the working
point (of the limited working range) of the sensor.
Example:
Working range v 8 – 12 m/s (1600 – 2400 ft/min) > calibration point at 10 m/s
(2000 ft/min);
working range T 18 – 22 °C (64.4 – 71.6 °F) > calibration point at 20 °C (68
°F).
4.9.2 Information on 2-point v/T Calibration
v/T calibration / adjustment is performed at 2 different calibration points.
To ensure the smallest possible deviation in measuring results over the entire
measuring range, the two calibration points should be selected as follows:
– The low calibration point should be in the lower third of the measuring
range.
– The high calibration point should be in the upper third of the measuring
range.
Example:
EE75 T3***HV23 – measuring range = 0 – 2 m/s (0 – 400 ft/min)
– Low calibration point (V-CAL LOW) should be around 0.4 m/s (0…0.7).
– High calibration point (V-CAL HIGH) should be around 1.8 m/s (1.4…2).
4.9.3 V Calibration Procedure Using the Configuration Software
1. Position the sensor head in the middle of the reference system (wind
tunnel).
2. Set the required calibration point in the reference system (wind tunnel).
3. Stabilise the probe at the reference velocity (for at least 1 minute).
4. Clicking on the “Velocity calibration” button opens the menu window shown
below.
5. Enter the velocity displayed by the reference system in the “Reference
value” input field.
6. Clicking “Save” adjusts the EE75 measuring value with the reference value.
7. In the case of 1-point calibration, the process is now complete.
8. For 2-point calibration, repeat steps 2-7.
4.9.4 T Calibration Procedure Using the Configuration Software
Click on the “Temperature calibration” button. The 1 or 2-point temperature
calibration procedure is similar to the velocity calibration (see chapter
4.9.3 – V Calibration Procedure Using the Configuration Software).
4.9.5 Activating Factory Calibration
Clicking the “Activate factory calibration” button deletes the customer
calibration data set for velocity and temperature and restores the factory
settings.
4.10 Measuring Values
The configuration software allows the EE75 measuring values to be queried periodically on the “Measuring Values” index card.
If the “Activate automatic Query” function is activated, all measuring values are downloaded according to the specified interval and displayed in the desingated fields.
This function is particularly useful for checking sensors, which do not have the (optional) display module.
4.11 Information
The “Information” tab contains general information on the sensor. It also
saves the date of the last customer calibration done with the configuration
software.
