1.2 Safety instructions
General Safety Instructions
Excessive mechanical loads and incorrect usage should always be avoided.
•
• Take care when unscrewing the filter cap as the sensor element could be damaged.
• The sensor is an Electro Static Discharge sensitive component (ESD). When touching
the sensor element, ESD protective measures should be followed.
• Grip sensors only at the lead wires.
• Installation, electrical connection, maintenance and commissioning should be performed
by qualified personnel only.
• The devices are constructed for the operation of separated extra-low voltage (SELV).
Safety instructions for use of the alarm module with voltages >50V
To insulate the optional alarm module from the low-voltage side of the transmitter, the
•
partition provided for this purpose must be fitted in the lower section.
• During operation of the instrument the modular housing must be completely closed.
• The protection class of an opened housing corresponds to IP00 and direct contact
with components carrying dangerous voltages is therefore possible. In general, work on live
components should be avoided and when absolutely necessary, should be performed by
qualified personnel only.
Safety instructions for use of the integrated power supply (option V01)
During operation of the instrument the modular housing must be completely closed.
•
• The protection class of an opened housing corresponds to IP00. In general, work on live
components should be avoided and when absolutely necessary, should be performed by
qualified personnel only.
• The bottom part and the middle part of the housing must be grounded during operation.
1.3 Environmental aspects
Equipment from E+E Elektronik® is developed with due consideration to all resultant
environmental issues. When you dispose the equipment you should avoid environmental
pollution.
For disposal of the transmitter the individual components must be sorted with care. The
housing consists of recyclable metal (aluminium, Al Si 9 Cu 3). The electronics must be
collected as electronic scrap and disposed of according to the regulations in force.

2. PRODUCT DESCRIPTION
The EE33 series provides all the functions of a multifunctional humidity/temperature transmitter with one major difference - it is equipped with a heated measurement cell.
The heated measurement cell contains a combined (monolithic) humidity/temperature
sensor element and enables reliable long-term measurements in extremely humid or
chemically polluted environments.
With a special high-pressure probe the transmitter can be used at process pressures up
to 100bar (1450psi).
The operating modes of the heated measurement cell depend on the conditions. The
parameters of the different operating modes are as follows:
Heat intensity:
Automatic recover: The measurement cell can be heated intensively to evaporate chemical
residue or temporary condensation.
Warming: The measurement cell can be warmed slightly to prevent condensation
in environments with continuous high humidity.
Heating time:
The measurement cell can either be heated briefly (the heating time can be defined in the
configuration software) before returning to the ambient temperature or it can be warmed
continuously.
Start of heating:
Manual: Heating is started by a control element on the PCB.
Automatic: Heating is triggered when a defined humidity set point is exceeded
(configuration software).
Recurrent: Heating is recurrent and triggered after a defined cycle time (configuration
software).
Distinctive models, sensing probes and mounting versions allow for the EE33 series to be
utilized in numerous applications.
2.1 Operating modes and conditions
2.1.1 Automatic ReCover (ARC)
Chemical pollution:
When capacitive humidity sensors are exposed to chemical pollution (e.g. detergent
residue), the presence of foreign molecules can distort the measurement reading.
The foreign molecules can be evaporated by heating the measurement cell briefly and
intensively. Reconditioning helps to minimize distorted measurement readings during the
calibration interval.
Temporary condensation:
Temporary dew (e.g. in misty environments) is identified by defining a humidity set point
value (e.g. 99%) and can be evaporated by heating the measurement cell intensively for
10 seconds.
Thanks to its monolithic structure, the measurement cell cools off quickly (approx.
3 minutes) to reach once again the same humidity content as the environment.
If condensation is still detected at the end of the heating and cool-down times, the process
starts again after a defined cycle time (30 minutes).
Hardware

2.1.2 Overheating / Warming (OH = Overheating)
Continuous high humidity:
Even the smallest deviation between the temperature of the sensor head and the ambient
temperature can cause dew on the sensor element in conditions of continuous high
humidity (e.g. in mushroom drying). Dew on the humidity sensor element prevents
accurate measurement of the actual humidity.
However, the EE33 series minimizes the relative humidity on the measurement cell
through regularly warming. The relative humidity and temperature of the warmed
measurement cell can be determined precisely thanks to its monolithic structure. The dew
point of the environment is calculated from the measuring values.
If the relative humidity has to be determined near condensation, the ambient
temperature can be measured with an additional temperature sensor to calculate
the relative humidity.
2.1.3 High process pressure up to 100 bar (1450psi) / high-pressure probe
(HPP = High Pressure Probe)
Thanks to the combination of the heated measurement cell with a new high-pressure
probe, the transmitter can be used in applications with high process pressure and wide
working range in humidity and temperature.
The special high-pressure probe's innovative pressure tight feed through sets it apart from
the remote probes in other models.
Special ball valves enable assembly without interrupting the process and are available on request.

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
underany 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).
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.
The temperature during installation may not vary more than
±4°C (±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°.
