2. Safety

2.1 Intended use

The combined bimetal thermometer is mainly used in the process industry to monitor process temperatures.

The combined bimetal thermometer has been designed and built solely for the intended use described here, and may only be used accordingly.

The technical specications contained in these operating instructions must be observed. Improper handling or operation of the combined bimetal thermometer outside of its technical specications 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.

WARNING!

Before installation, commissioning and operation, ensure that the appropriate bimetal thermometer has been selected in terms of measuring range, design and specic measuring conditions. The compatibility of the wetted parts of the process connection (thermowell, thermowell stem) with the medium must be tested. Non-observance can result in serious injury and/or damage to the equipment.

Further important safety instructions can be found in the individual chapters of these operating instructions.

2. Safety

2.2 Personnel qualication

WARNING! Risk of injury if qualication is insucient!

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 personnel who have the qualications described below.

■

Keep unqualied personnel away from hazardous areas.

Skilled personnel

Skilled personnel are understood to be personnel who, based on their technical training, knowledge of measurement and control technology and on their experience and knowledge of countryspecic regulations, current standards and directives, are capable of carrying out the work described and of independently recognising potential hazards.

2.3 Special hazards

WARNING!

Residual media in dismounted instruments can result in a risk to persons, the environment and equipment. Take sucient precautionary measures.

WARNING!

For lled instruments, make sure that the medium temperature is lower than 250 °C.

Reason: The sheath also contains a lling liquid; at a temperature > 250 °C, this liquid may become cloudy or change colour or, in some cases, may ignite.

4. Design and function

4.1 Description

This series of thermometers is designed for installation in pipes, vessels, plant and machinery.

The „Twin-Temp“ combined bimetal thermometer oers two measuring systems in one instrument.

A bimetal thermometer enables the visualisation of measured values on site without power supply, while, in addition, the integrated Pt100 resistance sensor provides an electrical signal for further processing. This design is particularly recommended for safety-critical applications and in case of limited space where the process can be opened only at one place.

5. Transport, packaging and storage

4.2 Scope of delivery

Cross-check scope of delivery with the delivery note.

5. Transport, packaging and storage

5.1 Transport

Check the instrument for any damage that may have been caused during transportation. Obvious damage must be reported immediately.

5.2 Packaging

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).

5.3 Storage Permissible conditions at the place of storage:

Storage temperature: -20 ... +60 °C

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

■

Potentially explosive environments, ammable atmospheres

Store the instrument in its original packaging in a location that fulls the conditions listed above. If the original packaging is not available, pack and store the thermometer as described below:

1. Wrap the thermometer in an antistatic plastic lm.

2. Place the thermometer, along with 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 model 54, Twin-Temp 9

6. Commissioning, operation

WARNING!

Before storing the instrument (following operation), remove any residual media. This is of particular impor-

tance if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic, radioactive, etc.

The use of liquid damping is always recommended for temperatures near the dew point (±1 °C around 0 °C).

6. Commissioning, operation

When screwing the instrument in, the force required to do this must not be applied through the casing, but only through the spanner ats provided for this purpose and using a suitable tool.

Installation with spanner

When using thermowells, they must be lled with a thermal contact medium in order to reduce the heat transfer resistance between the outer wall of the sensor and the inner wall of the thermowell. The working temperature of the thermal compound is -40 ... +200 °C.

WARNING!

Do not ll hot thermowells. There is a risk of the oil spraying out!

6. Commissioning, ... / 7. Maintenance and ...

CAUTION!

When using thermowells, please ensure that the stem does not touch the bottom of the thermowell since, due to the dierent expansion coecients of the materials, the stem may become

Stem

buckled at the bottom of the thermowell. (Formula for the calculation of the stem length l1 see the respective thermowell‘s data sheet)

Required safety clearance

7. Maintenance and cleaning

7.1 Maintenance

The combined bimetal thermometer is maintenance-free! The indicator should be checked once or twice every year. To do this the instrument must be disconnected from the process and checked using a temperature calibrator.

Repairs must only be carried out by the manufacturer.

7.2 Cleaning

CAUTION!

■

Clean the thermometer with a moist cloth.

■

Wash or clean the disconnected thermometer before returning it in order to protect personnel and the environment from exposure to residual media.

CAUTION!

If faults cannot be eliminated by means of the measures listed above, the instrument must be shut down immediately, and it must be ensured that pressure and/or signal are no longer present, and it must be prevented from being inadvertently put back into service. In this case, contact the manufacturer. If a return is needed, follow the instructions see chapter 9.2 "Return".

9. Dismounting, return and disposal

WARNING!

Residual media in dismounted instruments can result in a risk to persons, the environment and equipment. Take sucient precautionary measures.
