2. Design and function

2.1 Description

The model TC47 thermocouples are used for temperature measurement in the range from

0 … 400 °C [32 … 752 °F]. They are particularly suitable for those applications in which the

metal probe tip is mounted directly into bored holes, e.g. in machine components or directly

into the process, for any application without chemically aggressive media or abrasion.

The thermocouple is designed as a tube and wire construction. This consists of a metal

probe tip, in which the thermocouple cable is inserted and fixed, or a metal fixing element

onto which the thermocouple cable is attached.

Unless otherwise specified, the measuring points will be delivered isolated from the probe

tip (ungrounded).

For specific applications, e.g. surface temperature measurements, the measuring points of

the thermocouples can be delivered welded to the probe tip.

2.2 Scope of delivery

Cross-check scope of delivery with delivery note.

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 thermocouples described here are suitable for temperature measurement in the

plastics industry. Depending on design, they can be mounted directly into the process

or within a thermowell. The design of the thermowell can be selected as desired, but the

operational process data (temperature, pressure, density and flow rate) must be taken into

account.

The instrument is not permitted to be used in hazardous areas!

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 and the related data

sheets must be observed. Improper handling or operation of the instrument outside of its

technical specifications requires the instrument to be taken out of service immediately and

inspected by an authorised WIKA service engineer.

The manufacturer shall not be liable for claims of any type based on operation contrary to

the intended use.

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.

Keep the packaging as it will provide optimum protection during transport (e.g. change in

installation site, sending for repair).

Permissible conditions at the place of storage:

Storage temperature: 0 ... 70 °C [32 ... 158 °F]

Humidity: 35 ... 85 % relative humidity (non-condensing)

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. Wrap the instrument in an antistatic plastic film.

2. Place the instrument, along with the shock-absorbent material, in the packaging.

3. If stored for a prolonged period of time (more than 30 days), place a bag containing a

desiccant inside the packaging.

WIKA operating instructions, models TC47 11

5. Commissioning, operation

Only use original parts.

WARNING!

Physical injuries and damage to property and the environment caused

by hazardous media

Upon contact with hazardous media (e.g. oxygen, acetylene, flammable

or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,

radioactive), and also with refrigeration plants and compressors, there is a

danger of physical injuries and damage to property and the environment.

Should a failure occur, aggressive media with extremely high temperature

and under high pressure or vacuum may be present at the instrument.

▶

For these media, in addition to all standard regulations, the appropriate

existing codes or regulations must also be followed.

▶

Wear the requisite protective equipment (see chapter 3.6 “Personal

protective equipment”).

DANGER!

Danger to life caused by electric current

Upon contact with live parts, there is a direct danger to life.

▶

The instrument may only be installed and mounted by skilled personnel.

▶

Operation using a defective power supply unit (e.g. short-circuit from the

mains voltage to the output voltage) can result in life-threatening voltages

at the instrument!

5.1 Mechanical connection

The installation of the thermocouple should be made so that the temperature neither drops

below the permissible operating temperature (environment, medium) nor exceeds it, even

when taking convection and heat radiation into account.

5.2 Electrical connection

■

Only connect cables and lines in an unpowered state!

■

Fine-stranded leads must be finished with end splices.

■

Cables used must comply with the respective requirements in terms of stability and

temperature.

■

Connection cables must be run so that any mechanical damage is prevented.

8. Dismounting, return and disposal

8.1 Dismounting

WARNING!

Physical injuries and damage to property and the environment

through residual media

Upon contact with hazardous media (e.g. oxygen, acetylene, flammable

or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,

radioactive), and also with refrigeration plants and compressors, there is a

danger of physical injuries and damage to property and the environment.

▶

Before storage of the dismounted instrument (following use) wash or

clean it, in order to protect persons and the environment from exposure to

residual media.

▶

Use the required protective equipment (depending on the application; the

thermometer itself is basically not dangerous).

▶

Observe the information in the material safety data sheet for the

corresponding medium.

Only disconnect the thermometer once the system has been depressurised.

WARNING!

Risk of burns

During dismounting there is a risk of dangerously hot media escaping.

▶

Let the instrument cool down sufficiently before dismounting it!

DANGER!

Danger to life caused by electric current

Upon contact with live parts, there is a direct danger to life.

▶

The dismounting of the instrument may only be carried out by skilled

personnel.

▶

Only dismount the pressure measuring instrument/measuring assembly/test

and calibration installations once the system has been isolated from power.

8.2 Return

Strictly observe the following when shipping the instrument:

All instruments delivered to WIKA must be free from any kind of hazardous substances

(acids, bases, solutions, etc.) and must therefore be cleaned before being returned.

WARNING!

Physical injuries and damage to property and the environment

through residual media

Residual media in the dismounted instrument can result in a risk to persons,

the environment and equipment.

▶

With hazardous substances, include the material safety data sheet for the

corresponding medium.

▶

Clean the instrument, see chapter 7.2 “Cleaning”.
