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. Safety

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.
