2. Design and function

2.1 Description

Thermocouples are used for temperature measurement in industrial applications such as

heat-treatment furnaces, sulphur recovery plant or gas reactors.

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).

The model TC80 thermometer corresponds to DIN EN 50446 and uses metallic and/or

ceramic protection tube materials. The model TC82 protects the thermocouple using one or

two ceramic protection tubes or a thermowell made from silicon carbide. For both models,

the possibility exists of optionally increasing the service life through the use of gas purging.

The TC83 Calitum®and TC84 thermometers, in addition to the ceramic exterior protection

tube, use a further monocrystalline sapphire protection tube, which makes purging

unnecessary.

The instrument has been designed and built solely for the intended use described here,

and may only be used accordingly.

2.2 Scope of delivery

Cross-check scope of delivery with delivery note.

WIKA operating instructions models TC80, TC82, TC83, TC8410

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 the shock-absorbent material, in the packaging.

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

5. Commissioning, operation

WARNING!

Damage to the measuring instrument by operation outside the upper or

lower limits of the operating temperature

Failure to observe the permissible operating temperature, also taking into

account convection and radiation, can even cause damage to the thermometer

during mounting.

▶

The upper and lower limits of the specified operating temperature range

must not be exceeded.

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), 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 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.

5.1 Mechanical mounting

5.1.1 Mounting instructions for electrical thermometers with ceramic protection tube

Ceramic protection tube materials withstand changes in temperature only to a limited

extent. A temperature shock can therefore easily result in stress cracks and consequently

in damage to the protection tube.

Insert thermocouples with ceramic or sapphire protection tubes into the hot process slowly.

In accordance with DIN 43724, an insertion speed of 1 cm/min [0.375 in/min] is

recommended for protection tubes with a diameter of 25/26 mm [approx. 1 in]. For smaller

diameters of 10/15 mm [0.375/0.625 in], this can be increased to 50 cm/min [20 in/min]. As

a basic principle, higher process temperatures require a lower insertion speed.
