2. Safety

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.

2.1 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.

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 country-

speci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 applica-

tions and in case of limited space where the process can be opened

only at one place.

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 trans-

port (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.

5. Transport, packaging and storage

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.

6. Commissioning, operation

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!
