•
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 polycarbonate or 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 EE35 series is based on a functional, user-friendly housing concept and on the
proven polymer humidity sensors of the HC series.
A specially developed and in the instrument integrated autocalibration process enables
measurements in a range of -60...+60 degC Td (-76...140°F Td)with a accuracy of
±2 degC Td (36°F Td).
In order to ensure this high accuracy at low humidities, also the smallest drift effects of the
humidity sensor element have to be compensated.
Therefore the autocalibration process will be accomplished every 30 minutes and last
about 3 minutes. During the autocalibration procedure output signal remains unchanged.
Two freely configurable and scaleable analogue outputs are available for the two
measurement values (Td, T). When the dewpoint temperature is below 0 degC (32°F), the
transmitter calculates the frostpoint.
An optional hygrostat output, which can be set by means of a potentiometer, provides an
alarm signal in a simple way when the threshold of the permitted dewpoint is exceeded.
An optional display for the measurement values and the associated MIN/MAX values
allows a quick overview of the current situation.

3.2 Installation of the probe
Select a place that is as clean as possible with surrounding
conditions that permit an optimal measurement of the process.
The air must be able to circulate freely around the sensor
element.
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 followed when working on the sensing probe or in its vicinity.
You should not bend directly over the sensing probe under any
circumstances!

maximum installation depth
Hardware
During the installation of the sensor head, make sure that you
do not damage the surface of the sensing probe! Damaging
the probe tube could lead to damaged sealing elements (con sequence: leakage rate and pressure loss) and to problems
during removal (jamming).
Before the sensing probe is installed, make sure that it is free
from contaminants (grease, dirt).

3.2.2 Installation of the probe directly in the process
If the probe is mounted in the measurement chamber, make
sure that it is mounted vertically and that the sensor head
points downwards.

stop valve
For direct probe installation, a stop valve should be provided
on both sides of the process. This allows the sensor head to
be removed for maintenance and calibration without any
problems.
If the sensor head 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:
1st step:
Mount the probe with the stop valve closed.
2nd step:
Insert the sensor head 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 means of the
ball valve set
For a ball valve installation, the system to be measured does
not have to be emptied or shut down in order to install or
remove the probe.
Install the sensor head perpendicular to the direction of flow.
The pressure of the process must be below 20 bar (290psi).
The two metal sealing rings (see figure) should be changed
every time after the probe is unscrewed.
INSTALLATION OF THE PROBE:
1st step:
Mount the probe with the ball valve closed.
2nd step:Open the ball valve.
3rd step:Insert the sensor head 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 tightening torque results in a smaller tensioning force
(fixing force) of the clamping sleeve. There is the risk of
injury due to sudden expulsion of the sensing probe.
A too high tightening torque can lead to permanent deformation
of the clamping sleeve and the sensing probe. This can make
the removal and re-installation more 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.
Pay attention to the sealing element 1 while mounting or removing the probe. This
sealing element has to be put in a proper form.
