3 Product description
3.1 General information
The GTF 111-Ex and GTF 112-Ex temperature probes are designed as integrated probes for
use in explosion-prone areas. The probes are very small, so they can be used in places that
are difficult to access. The probes are equipped with an M12 connector.
The measuring insets of the GTF 111-Ex and GTF 112-Ex are firmly sealed and cannot be
exchanged. They are available in the following sensor element group:
resistance thermometer: Pt 100 or Pt 1000.
Only mineral-insulated resistance thermometers are used as sensor elements.
The materials used for the probe parts that come into contact with the medium consist of
stainless steel (e.g. 1.4404, 1.4435, 1.4571). This guarantees high resistance to a wide variety
of chemical compounds.
The range of use, depending on the version, theoretically covers a medium temperature of
-200 °C to +600 °C. This is limited by the temperature class of the Ex area!
At temperatures above 100 °C the probe must have a correspondingly large neck length.
GTF 111-Ex must have a sufficient distance from the compression fitting to the sleeve at tem-
perature being kept above 100 °C. For this purpose, an additional tubular sleeve is provided as
a stop for the neck length.
Recommendation for minimum necessary extension tube lengths with good ventilation:
Measuring temperatures up to 250 °C => extension tube length 50 - 100 mm
Measuring temperatures up to 400 °C => extension tube length 100 - 200 mm
Measuring temperatures above 400 °C => extension tube length 200 mm or long
There a multitude of base types of GTF 111-Ex and GTF 112-Ex available that can all be
custom assembled.
We recommend the series GTF 103-Ex for applications with head transmitters or terminal
block.

3.3 Which temperature probe, transmitter do I need?
You can easily determine the temperature probe or temperature transmitter for your specific
application from the table below.
Zone 0 or 20
If the temperature must be detected in Ex Zone 0 or 20, the appropriate GTF111-Ex or
GTF112-Ex temperature probe in ignition protection class Ex ia IIC T6 can be used.
Only ATEX-approved devices can be used as display and/or control devices that meet the re-
quirements of the corresponding zones.
Zone 0/1 or 20/21 (zone-separating)
If the temperature must be detected in Ex Zone 0 or 20 and the probe connection is outside of
this zone, the probe must be installed as appropriately zone-separating. For this purpose, the
appropriate, suitable GTF111-Ex or GTF112-Ex temperature probes in ignition protection class
Ex ia IIC T6 are used.
Only ATEX-approved devices can be used as display and/or control devices that meet the re-
quirements of the corresponding zones.
Zone 1, 2 or 21, 22
If the temperature must be detected in Ex Zone 1, 2 or 21, 22, the appropriate GTF111-Ex or
GTF112-Ex temperature probe in ignition protection class Ex ia IIC T6 or Ex e IIC T6 and Ex ia
IIIC or Ex mb IIIC can be used.
If the display and/or control device is in Zone 1, 2 or 21, 22, only ATEX-approved devices of
the appropriate zone can be used.
If the display and/or regulating device is outside of the Ex area, Ex approval is not required if
the GTF 103-Ex temperature probe in ignition protection class Ex e IIC T6 or Ex tb IIIC is used
and the safety instructions from chapter 2.4 are observed.

4.2 Connection values and environmental conditions
A maximum of 25 mW should be applied to the measuring current circuit. When this value is
observed, the temperature on the probe tube increases by a maximum of 4 °C in relation to the
environmental temperature. The GTF 111-Ex and GTF 112-Ex must only be used if this tem-
perature increase in relation to the medium temperature within the container is permissible.
If an additional load is applied to the measuring current circuit in the event of an error, the in-
dependent heating of the probe tube must be factored in during use.
The sum of the medium temperature and the temperature from independent heating of
the probe tube must always - even in the event of an error - be less that the ignition
temperature of the medium!
