1. Introduction
1.1 General
The temperature-probes GTF 103-Ex are mounting probes for usage in potentially explosive
atmospheres of all zones. Greatest flexibility is given by the modular build up of the GTF 103-Ex.
The temperature–probes are equipped with a head (IP 65). The head can function as a
connection head or as a housing for a head transmitter .
The probe-inserts of the GTF 103-Ex are available for two different sensor-groups:
resistance thermometer: Pt 100, Pt 1000 or thermocouple : type K, type N (standard).
Only mineral insulated sensor elements are used. The GTF 103-Ex can be employed in
medium-temperatures from –200°C to + 900°C.
The permissible ambient temperature in the area of the connection head depends on the
temperature class, the potential explosive zone, the medium-temperature, and the screwed
cable gland. For the standard screwed cable gland the permissible maximal ambient temperature
ranges from –20°C to + 60°C ( see chap. 2.3) and for the modification „ higher ambient
temperature „ (GTF 103-Ex-...H...-types) from –20°C to +80°C.
Apart from the probe-inserts with a probe diameter 3mm all probe-inserts of the GTF 103-Ex are
exchangeable.
The used material of the probes which encounter the medium are made of stainless steel
(e.g. 1.4404, 1.4435, 1.4571 or Inconel 600 ). This ensures high stability against many chemical
compounds.
If the medium-temperature exceeds 100°C all GTF 103-Ex must have a neck tube length of at
least 50mm (standard). It is also possible to produce longer neck tubes.
You can choose between 48 GTF 103-Ex basis-types . Also all basis-types could be
produced according to your instructions.
1.2 Which temperature-probe, transmitter, display etc. do I need?
You can easy find out the needed temperature-probe or transducer for your special application
from the table given below.
Zone 0 or 20
A GTF 103-Ex can be used, if the temperature has to be acquired in Ex-zone 0 or 20. Only
ATEX- certified display- and control-devices, matching the demands of the certain zone, are
allowed to be used.

Zone 1,2 or 21, 22
A GTF 103-Ex matching the protection class EEx e II T6 or EEx ia IIC T6 can be used, if the
temperature has to be acquired in EX-zone 1, 2 or 21, 22. In case the controlling- or displaying
device is also in zone 1, 2 or 21, 22 only ATEX certified devices matching the demands of the
certain zone are allowed to be used.
In case the controlling- or displaying device is beyond the explosion hazardous area, this device
does not need an Ex-certification if a temperature-probe GTF 103-Ex matching the protection
class increased safety (EEx e II T6) is used and the safety instructions given in chapter 2 are
fulfilled.

2. Safety instructions
2.1 General
.
1. Only install the GTF 103-Ex according to the given manufacturer’s instructions and observe
general standards and precepts.
2. The temperature sensors with the type of protection “Increased Safety” (e) are allowed to be
connected only to the resistance sensors or thermocouples according to the relevant standard for
this part. The nominal electrical operating parameters may not exceed.
3. Every temperature sensor with the type of protection „Increased Safety“ (e), has to be used with
a series fuse, which is suitable for the possible short-circuit current of 1500A. The series fuse
can be installed into the associated supply device or into the evaluation device.
4. Setting up the head transmitter is only allowed to be done in a non hazardous area.
5. Before changing the measuring-insert the connections must be disconnected.
6. In the case of using the complete GTF 103-Ex in the hazardous area which required the
category 1, the safety instructions for zone 0 or zone 20 have to be fulfilled.
7. Only use cable with allowable diameter and associated sealings of the cable entry point.
The connection piece of the cable entry point must not be detached. Use blue pressure screw of
the cable entry point for intrinsic safety circuits.
8. Arrange circuit points according to the given connection diagram. The anode (positive pole) of
thermocouples is marked with a red label.
9. The maximal ambient temperature which are specified in the EC-type-examination certificate do
not may be overranged in the entire area of the connection head. Influences of adjacent heat-
sources are to be considered.
10. The self heating of the device’s tube has to be considered for the application, if loading the
measure-circuitry with more than 40mW.
The summation of the medium-temperature and the temperature of the sensor-tube from
the device’s self heating must always be lower than the ignition temperature of the
medium.
11. The chemical resistance of the material has to be checked with the manufacturer, if using in
aggressive mediums.
12. The probe line of the temperature sensor is to be installed in such a way which ensure sufficient
protection against mechanical damage. The bending especially of the long sensor tube has to be
prevent. Where appropriate fasten elements are to be mounted in suitably distances.
2.2 Safety instructions for zone 0 or zone 20
These instructions are only valid if the complete GTF 103-Ex is to be installed in zone 0 or zone 20.
1. The explosive mixtures are allowed to occur only in atmospheric conditions of
–20°C ≤Ta ≤+60°C and 0,8 bar ≤p ≤1,1 bar.
2. Please take notice of the limited ambient temperatures (see chapter 2.3)
3. The power supply circuit must fulfill ignition classification EEx ia IIC .
4. The GTF 103-Ex materials must be completely compatible with the measured media
(housing : aluminium, sealing: silicon; label: polyester with acrylic glue)
5. The GTF 103-Ex must be installed so that there is no chance of electrostatic charging.

2.4 Connection values and ambient conditions
The measure-circuit should not be loaded with more than 40mW. When not exceeding
this value, the temperature at the sensor-tube will raise 4°C maximum compared to
ambient temperature. The temperature probe GTF 102-Ex must only be used, if this
increase of temperature compared to the medium-temperature within the
container is allowable.
The self heating of the device has to be considered for the application, if loading the
measure-circuit in fault with more than 40mW. The summation of the medium-
temperature and the temperature of the sensor-tube from the device’s self heating up
must always, even in fault, be lower than the ignition temperature of the medium.

device must be objected.

3.2. Thermocouples type K and type N
The connection for the anode (positive pole ) is marked with a red label.
3.3. Screwed cable gland
The protection-degree of the connection head is IP 65. The user is committed to use
cables with the specified diameter only . The assembly has to be done appropriate.
If the assembly is not done appropriate explosion hazard is given !
Attention: the cable has to be protected against pull out (e.g. with a cable
clamp).
Factory-made the connection piece of the screwed cable gland is clotted with the
sensor head. Violent dismounting or detaching is not permissible (Torque > 3,75 Nm).
The pressure screw of the screwed cable gland has to be tested for leak, regularly and
has to be tightened if necessary. Reconstruction or modification at the screwed cable
gland or the sensor are not allowed. Only original parts are allowed to be used if repair
work is necessary.
3.3.1 Standard
Only round cables with the following external diameters (ED) are allowed to use:
Use the right sealing for your cable( see figure 4). The pressure screw has to be
tightened well to ensure the protection-degree IP 65 ( 2,50Nm). Violent tightening
can lead to impairment of the protection-degree.

4. Probe-types and areas of application
The GTF 103-Ex are available in 48 different designs.
The GTF 103-Ex are equipped with a head . The head has to offer sufficient space for a
head transmitter. Furthermore the measuring inserts of the GTF 103-Ex are changeable
without dismounting the whole probe ( apart from probe-tube ED= 3mm).
All further specifications adapt to the sensor, the temperature-range, the ambient
temperature, and the needed type of protection.
Standard-probes are manufactured with a probe-length of 100mm, a probe-diameter of
6mm, a screw thread G=1/2” and for media-temperatures > 100°C with a neck tube-length
of 50mm.
