Ceramic outer protection tube
2.2 Description
This thermocouple is used for temperature measurement in industrial applications.This
high-temperature thermocouple with a gas-tight sapphire protection tube has been
specifically developed for use in gas reactors.Through the monocrystalline structure, the
sapphire protects the precious metal of the thermocouple from poisonous toxic media in
the aggressive atmosphere of the gasification reactor.
For the connection side, the thermometer is fitted with a case.The case design contains
the connection terminals.
This document describes standard versions of instruments. For applications in hazardous
areas special instrument designs are required.
For further information for operation in hazardous areas, see the additional information for the
corresponding ignition protection type (separate document).

3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury
or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or
damage to property or the environment, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in burns, caused
by hot surfaces or liquids, if not avoided.
Information
... points out useful tips, recommendations and information for efficient and
trouble-free operation.
3.2 Intended use
The model TC84 sapphire-design thermocouple, with gas-tight sapphire protection tube,
described here is suitable for temperature measurement in critical industrial applications
such as gasification or GtL reactors and is suitable for direct installation into the process.
Due to its monocrystalline structure, the sapphire protection tube extends the life of the
thermocouple's precious metal by 3 times, in comparison to purely ceramic protection
tube materials. As a result of the pressure-tight, hermetically sealed junctions between the
sapphire and metal protection tube, and also a multifold sealing system in the connection
housing, toxic gases are prevented from being able to escape from the reactor.
Neither repairs nor structural modifications are permitted, and any would void the
guarantee and the respective certification. The manufacturer shall not be responsible for
constructional modifications after delivery of the instruments.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.

3.3 Responsibility of the operator
The system operator is responsible for selecting the thermometer or protection tube, and
for the selection of their materials, so as to guarantee their safe operation within the plant
or machine.When preparing a quote, WIKA can only give recommendations which are
based on our experience in similar applications.
The safety instructions within these operating instructions, as well as the safety, accident
prevention and environmental protection regulations for the application area must be
maintained.
The operator is obliged to maintain the product label in a legible condition.
3.4 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient
Improper handling can result in considerable injury and damage to
equipment.
▶
The activities described in these operating instructions may only be
carried out by skilled electrical personnel who have the qualifications
described below.
Skilled electrical personnel
Skilled electrical personnel are understood to be personnel who, based on their technical
training, know-how and experience as well as their knowledge of country-specific
regulations, current standards and directives, are capable of carrying out work on
electrical systems and independently recognising and avoiding potential hazards.The
skilled electrical personnel have been specifically trained for the work environment they
are working in and know the relevant standards and regulations.The skilled electrical
personnel must comply with current legal accident prevention regulations.
Operating personnel
The personnel trained by the operator are understood to be personnel who, based on their
education, knowledge and experience, are capable of carrying out the work described and
independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive
media.

4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during internal
transport, proceed carefully and observe the symbols on the packaging.
▶
With internal transport, observe the instructions in chapter 4.2 “Packaging
and storage”.
If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in instrument malfunction. Before putting it back into operation,
wait for the instrument temperature and the room temperature to equalise.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Store the Styrofoam packaging as well as the protective transport tube of the probe for any
return transport (repair option).
To unpack the TC84 thermocouple, follow chapter 5.1 “Unpacking the thermocouple and
dismounting the protective transport tube”.
Permissible conditions at the place of storage:
Storage temperature: -40 ... +80 °C [-40 ... +176 °F]
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Hazardous environments, flammable atmospheres
Store the instrument in its original packaging in a location that fulfils the conditions listed
above. If the original packaging is not available, pack and store the instrument as described
below:
1. Place the instrument, along with shock-absorbent material, in the packaging.
2. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.
