2. Safety
2.1 Explanation of symbols
DANGER!
... indicates a potentially dangerous situation in the hazardous area that can
result in serious injury or death, if not avoided.
2.2 Intended use
The thermometers described here are suitable for temperature measurement in hazardous
areas like e.g. sulphur recovery units (SRU).
The electrical thermometer model TC8x-F is made of a module (model TC8x-M), which is
fitted to an Ex d certified case.The module consists of the flange assembly with ceramic
tubes, all parts of electrical insulation of the thermocouple wires and a gas-tight bushing to
limit the flameproof area.
The sensing part of the module is made of ceramic insulated thermocouple wires.
The thermometer/module will be mounted to an Ex d or Ex db certified case manufactured
by WIKA series 1/4000F, 7/8000 or 5/6000.The case and covers are made of stainless
steel or aluminum.The cover could be optionally provided with a glass lens (window).
Alternatively, the thermometer will be mounted to other certified cases or assemblies
as listed in the “WIKA ATEX and IECEx Ex-d housing and device list” (article no.
14405410.01).
3 different variants are available:
■
Variant 1: The thermometer is fitted to a certified empty case in the type of protection
“flameproof enclosure”.Terminals are mounted inside the case.
■
Variant 2: The thermometer is fitted to a certified empty enclosure in the type of
protection “flameproof enclosure”. Electronic equipment is mounted inside the case.
■
Variant 3: The thermometer is fitted to a certified apparatus (transmitter) in the type of
protection “flameproof enclosure”.The thermometer is marked II 2/-G Ex db IIC Gb/-.

DANGER!
Danger to life from explosion
Through working in flammable atmospheres, there is a risk of explosion
which can cause death.
▶
Only carry out set-up work in non-hazardous environments!
▶
Do not open the instrument while under voltage.
DANGER!
Danger to life from explosion
By using a measuring insert without a suitable connection head (case), an
explosion risk occurs which can cause fatalities.
▶
Only use the measuring insert in the connection head designed for it.
DANGER!
Danger to life due to loss of explosion protection
If the allowable thread gaps and the corresponding tightening torques are not
observed, this can lead to a loss of the explosion protection.
▶
Ensure the number of engaged threads in accordance with chapter 3.8
and the tightening torques in accordance with chapter 3.2.
Observe the special conditions (see chapter 4 “Special conditions for use (X conditions)”).
3.1 Mechanical mounting
With pre-assembled connection heads, the direct threaded connection of the thermometer
to the connection head or case must not be twisted or opened. Any alignment of the case
may only be made using the optional “nipple-union-nipple” neck tube.
Certified and listed field cases (variant 3) should only be fitted and installed by a specialist
trained to the latest technological standards.

■
Only ever screw in, or unscrew, the instrument via the spanner flats and to the
prescribed torque using an appropriate tool.
■
The correct torque depends on the dimensions of the connection thread and the sealing
used (form/material).
■
When screwing in or unscrewing the instrument, do not use the connection head as
contact surface.
■
When screwing in the instrument, please observe that the threads are not skewed.
■
Assure that the purge gas connection is tighten and no gas can escape, so that there is
no carry-through between zones.

3.3 Locking screw
Always tighten the locking screw to prevent unintended opening
of the head with flameproof enclosure.
Before opening the head, always loosen the locking screw
sufficiently.
3.4 Electrical mounting
■
For the installation of the thermometer, only components (e.g. cables, cable glands,
etc.) permitted for “flameproof enclosure” may be used.
■
Using a transmitter/digital display (option):
- Observe the contents of these operating instructions and those of the transmitter/
digital display (see scope of delivery).
- Observe the relevant regulations for installation and use of electrical systems, and also
the regulations and guidelines for explosion protection.
■
The temperature resistance of the connecting cables, the connection heads, the
cable entries and if necessary the blanking connectors shall be at least as high as the
maximum permissible ambient temperature and shall be at least as low as the minimum
permissible ambient temperature.
■
Do not fit any batteries or capacitors into the flameproof case.
■
Mounting within metallic enclosures:
The case must be grounded against electromagnetic fields and electrostatic charge.
It must not be connected separately to the equipotential bonding system. It is sufficient
if the process connection has a solid and secured contact with the metal vessel or its
structural components or pipelines, so long as these components are connected to the
equipotential bonding system.
■
Mounting within non-metal vessels:
All electrically conductive thermometer components within the hazardous area must be
provided with equipotential bonding.

wenn sie nicht gemieden wird.
2.2 Bestimmungsgemäße Verwendung
Die hier beschriebenen Thermometer sind geeignet zur Temperaturmessung in explosions-
gefährdeten Bereichen wie z. B. Schwefelrückgewinnungsanlagen (SRU).
Das elektrische Thermometer Typ TC8x-F besteht aus einem Modul (Typ TC8x-M), das an
einem Ex d zertifizierten Gehäuse befestigt ist. Das Modul besteht aus der Flanschanord-
nung mit Keramikrohren, allen Teilen der elektrischen Isolierung der Thermoelementdrähte
und einer gasdichten Durchführung zur Begrenzung des druckfesten Bereiches.
Der Sensorteil des Moduls besteht aus keramisch isolierten Thermoelementdrähten.
Das Thermometer/Modul Typ TC8x-M wird an einem Ex d- oder Ex db-zertifizierten
Gehäuse der WIKA-Serie 1/4000F, 7/8000 oder 5/6000 montiert. Das Gehäuse und die
Abdeckungen sind aus CrNi-Stahl oder Aluminium gefertigt. Die Abdeckung kann optional
mit einer Glaslinse (Fenster) versehen werden.
Alternativ wird das Thermometer an andere bescheinigte Gehäuse oder Baugruppen
montiert, wie sie in der „WIKA ATEX and IECEx Ex-d housing and device list“ (Artikelnum-
mer 14405410.01) aufgeführt sind.
Es stehen 3 verschiedene Varianten zur Verfügung:
■
Variante 1: Das Thermometer ist an einem zertifizierten Leergehäuse in der Zündschutz-
art „Druckfeste Kapselung“ befestigt. Die Klemmen sind im Inneren des Gehäuses
montiert.
■
Variante 2: Das Thermometer ist an einem zertifizierten Leergehäuse in der Zündschutz-
art „Druckfeste Kapselung“ befestigt. Elektronische Geräte sind im Inneren des Gehäu-
