2. PRODUCT DESCRIPTION
E+E Transmitter Series EE36 are specially designed for the measurement of
water content in oil.
The measured and the calculated values are available on two free scaleable
and configurable analogue outputs. In addition, an optional relay output can
be used for alarms and process control.
The modular housing enables a user-friendly operation and a quick
replacement of the sensor unit for service purposes.
The construction of the transmitter makes field and local loop calibration an easy task.
3. INSTALLATION
3.1 Installation of the housing
The necessary dimensions for the mounting holes can be
found in the drawings below.
3.2 Installation of the probe
Select a location with environmental conditions that permit an
optimal measurement of the process. The measuring medium
(e.g.: oil) shall be as clean as possible i.e. without contamination.
3.2.1 General safety instructions for installation
Because the sensing probe can be exposed to very high
pressures in the measurement environment, there is the risk of
sudden, unintentional expulsion of the probe during or after
improper installation. Therefore, special precautions should be
taken when working on the sensing probe or in its vicinity.
Bending over the sensing probe should be avoided under
any circumstances!
During the installation of the sensor probe, make sure that
the surface of the sensing probe is not damaged! Damaging
the probe could lead to damaged seals (consequence:
leakage and pressure loss) and to problems during removal
(jamming). Hardware

3.2.2 Installation of the probe directly in the process
For direct probe installation, a stop valve should be provided
on both sides of the probe insert. This allows the sensor probe
to be removed for maintenance and calibration without any
problems.
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 you remove the probe.
INSTALLATION OF THE PROBE:
The temperature during installation may not vary more than
±40 degC (±72°F) from the operating temperature.
1st step:
Install the probe with the stop valves closed.
2nd step:
Insert the sensor probe into the process.
3rd step:
To ensure a secure installation of the probe, the lock nut
must be tightened to a defined torque of 30 Nm.
If no torque-spanner is available tighten the lock nut by hand
as far as possible. Continue to turn with an open-ended
spanner ~50°.

3.2.3 Installation of the probe by utilizing the ball
valve set
The ball valve set allows for the removal of the probe
without interrupting the process.
Install the balve valve perpendicular to the direction of flow.
The pressure of the process must be less than 10 bar (145psi).
The two metal sealing rings (see figure) should be replaced
every time prior to re-installing the probe.
INSTALLATION OF THE PROBE:
The temperature during installation may not vary more than
±40 degC (±72°F) from the operating temperature.
1st step:
Install the probe with the ball valve closed.
2nd step:
Open the ball valve.
3rd step:
Insert the sensor probe through the ball valve into the process.
A manual pressing tool is recommended at high pressure.
4th step:
To ensure a secure installation of the probe, the lock nut
must be tightened to a defined torque of 30 Nm.
If no torque-spanner is available tighten the lock nut by hand
as far as possible. Continue to turn with an open-ended
spanner ~50°.

A too low torque results in a smaller tension force (fixing force)
on the clamping sleeve. There is the risk of injury due to sudden
expulsion of the sensing probe.
A too high torque can lead to permanent deformation
of the clamping sleeve and the sensing probe. This can make
the removal and re-installation difficult or impossible.
REMOVING OF THE PROBE:
1st step:
Firmly hold sensing probe. (Attention: do not bend connection cable)
2nd step:
Slowly loosen the lock nut with a spanner (spanner width 24) until
the expulsion force acts on the probe.
In the installed state, never completely remove the lock nut, only
unscrew it as much as necessary!
3rd step:
After the sensor head has been pulled out of the process up to the
stop, close the ball valve.
4th step:
Probe can now be completely removed.

7. HUMIDITY/TEMPERATURE CALIBRATION
The EE36 transmitter series can be calibrated in two ways:
-1-point humidity/temperature calibration: quick and simple calibration on a defined humidity/
temperature point (working point).
-2-point humidity/temperature calibration: simple calibration for accurate measuring results
over the whole humidity/temperature working range.
•To reach a temperature balance it is recommended to keep the transmitter and the
reference chamber (e.g. HUMOR 20,...) for minimum 4 hours in the same room.
• During stabilisation period and calibration procedure it is important to keep the temperature
constant in the reference climate chamber.
• For calibration the humidity sensor probe must be stabilised at least 20 minutes in the
reference chamber.
• Replace a dirty filter cap before calibration!
•A reduction of the stabilisation time can be achieved by cleaning the probe with
n-Hexan resp. n-Heptan. Sway the probe carefully in the solvent then drip off and after that
exhaust the air around the probe >0.5h.
Attention: Other solvents than above mentioned can corrode the humidity sensor!
7.1 2-point humidity calibration
For accurate adjustment over the whole working range a two point calibration is recommended.
• Start calibration at the low humidity calibration point!
• The humidity difference between the two points should be > 30%RH
• Low humidity point < high humidity point
• 2-point calibration may be performed directly on the circuit board or using the configuration
software supplied (for more details, see Configuration Software, chapter 5.4 ”Calibration”)

When the working range is limited to a certain more narrow range,
a calibration at one temperature point is sufficient.
• In accordance with the working range, either the high or low
calibration point should be selected. (CP ≥or < 45 degC / 113°F)
•This calibration causes an extra inaccuracy for the rest of the
working range.
• The 1-point temperature calibration may be performed directly on
the circuit board or using the configuration software supplied. (for
more details, see Configuration Software, chapter 5.4 “1-point
temperature calibration”)
1-point temperature calibration procedure on the circuit board:
1. Insert the sensor probe into the reference temperature
(calibration point) and stabilise for at least 20 minutes.
2. BUTTON S1: Pressing the button for 5 seconds starts the
procedure for the calibration mode temperature. The calibration
mode is indicated by the lit LED "D1" on the circuit board
3. BUTTON S1: Pressing the button for 5 seconds starts the
procedure. The calibration mode is indicated by the symbol
"CALIB HIGH" on the optional LC display (CP ≥45 degC / 113°F).
or
BUTTON S2: Pressing the button for 5 seconds starts the pro-
cedure. The calibration mode is indicated by the symbol "CALIB
LOW" on the optional LC display (CP <45 degC / 113°F).
4. BUTTON S1 (up) and S2 (down): Pressing one of the two
buttons will adjust the measuring value in steps of 0.1 degC up
or down to the reference value. The actual measuring value is
indicated on the display or can be measured with the analogue
output.
5. BUTTON S1 (store): Pressing the button for 5 seconds
stores the calibration value and the procedure is ended. LED
"D2" flashes to indicate exiting of the calibration mode and the
symbol "CALIB LOW" or "CALIB HIGH" will disappear from the
optional LC display.
BUTTON S2 (cancel): Pressing the button for 5 seconds the
calibration procedure will be ended without storing the
calibration values. LED "D2" flashes to indicate exiting of the
calibration mode and the symbol "CALIB LOW" or "CALIB
HIGH" will disappear from the optional LC display.

7.5 Resetting the customer calibration to the
factory calibration on the circuit board:
1. RH + T RESET:BUTTON S1 and S2: In neutral mode
pressing buttons S1 and S2 simultaneously for 10 seconds
customer calibration settings are reset to factory calibration.
A short flash of the LED "D1" indicates the reset.
or
2. RH RESET:BUTTON S2: Pressing the button for 5
seconds starts the procedure for the calibration mode RH.
Pressing buttons S1 and S2 simultanously for 10 seconds
customer calibration settings are reset to factory calibration.
A short flash of the LED "D1" indicates the reset.
or
3. Temp. RESET:BUTTON S1: Pressing the button for 5
seconds starts the procedure for the calibration mode T.
Pressing buttons S1 and S2 simultanously for 10 seconds
customer calibration settings are reset to factory calibration.
A short flash of the LED "D2" indicates the reset.

Hardware
Under certain circumstances, the capacitive humidity sensor element can get damaged. To avoid
the costly return of the entire transmitter to the manufacturer it is possible to replace the sensor.
Note:
•This will invalidate the factory calibration.
•The sensor elements should be touched by the lead wires only. (use tweezers!)
Sensor replacement procedure:
1) Switch off supply voltage.
2) Unscrew the filter cap.
3) Pull out the humidity sensor element with a tweezer.
4) Put in the new humidity sensor - the active side (side with the sensor pads) has to
face the inside. (see diagram)
5) Screw on the filter cap. (in case of pollution replace it by a new filter cap)
6) Establish connection to PC. (RS232)
7) Switch on the supply voltage.
8) Start configuration software on PC.
9) For further instructions, see Configuration software, chapter 5.3 "Sensor/Probe replacement"
active side
Transmitters of the EE36 series are available with an optional remote sensor probe that
can be plugged into the middle section of the housing. If the sensor probe is damaged
(damage to the cable, mechanical destruction of the sensor probe) it is
possible to replace the probe.
Note:
This will invalidate the factory calibration.
Sensor probe replacement procedure:
1) Switch off supply voltage.
2) Remove damaged sensor probe.
3) Plug replacement probe onto middle section of the housing.
4) Establish connection to PC (RS232).
5) Switch on power supply voltage.
6) Start configuration software on PC.

Cleaning of humidity and temperature sensors from oil residue:
1) Remove filter cap carefully, do not touch the sensors
2) Emerge the measuring head in N-HEPTAN and swirl for approx. 30 seconds
3) Remove excess liquid and allow to air dry for approx. 30 minutes
4) Screw on filter cap carefully
Cleaning of the measuring head is recommended before emerging in other oil and
before a calibration.
