2. Safety
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate thermowell has been selected in terms of measuring range, design and specic measuring
conditions.
Before installation, commissioning and operation, ensure that the thermowell material used is chemically resistant/neutral to the medium being measured and that it
withstands the mechanical stresses from the process.
Non-observance can result in serious injury and/or damage to equipment.
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
Thermowells are used to protect temperature sensors from the process conditions. Furthermore, thermowells enable the removal of the temperature sensor without having to shut down the
process; and they guard against damage to either the environment or to personnel, which might
be caused by escaping process media.
The thermowell has been designed and built solely for the intended use described here, and may
only be used accordingly.
The technical specications contained in these operating instructions must be observed. Should
the thermowell be improperly handled or operated outside of its technical specications, it has to
be inspected immediately.
GB
The manufacturer shall not be liable for claims of any type based on operation contrary to the
intended use.
2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
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 qualications described below.
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-specic regulations, current standards and directives, are capable of carrying out the
work described and independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive or toxic
media.

2.3 Special hazards
WARNING!
GB
For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids,
and refrigeration plants, compressors, etc., in addition to all standard regulations, the
appropriate existing codes or regulations must also be followed.
Make sure that the thermowell is suciently earthed.
WARNING!
Residual media on dismounted thermowells can result in a risk to persons, the
environment and the equipment. Take sucient precautionary measures.
3. Specications
For specications see the appropriate WIKA data sheets for current thermowell versions and the
order documentation.
4. Design and function
4.1 Description
Metal thermowells can be manufactured as solid-machined or fabricated versions. Thermowells
can be connected to the process by screw-, weld- or ange-tting. The temperature sensor is
directly fastened to the thermowell using a female or male thread or by means of an neck tube.
If thermowells made of metallic materials do not show a sucient temperature or corrosion resistance during continuous operation at temperatures above 1200 °C, ceramic thermowells should
be used.
4.2 Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check thermowell for any damage that may have been caused by transport. 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. Transport, packaging and storage / 6. Commissioning, operation
5.3 Storage
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects (for thermowells with plastic coating)
■
Mechanical vibration, mechanical shock (putting it down hard)
WARNING!
Before storing the thermowell (following operation), remove any residual media. This
is of particular importance if the medium is hazardous to health, e.g. caustic, toxic,
carcinogenic, radioactive, etc.
6. Commissioning, operation
6.1 Mounting
During mounting (especially with ceramic thermowells) the thermowells should not be subjected
to thermal shocks or mechanical impacts.
Insert the thermowell into the process adapter without forcing or damaging it. The thermowell must
not be bent or altered in order to mount it.
The exception is the retrospective machining of the support ring in order that the thermowell is
supported free of play within the nozzle ("interference t"). The retrospective adjustment of a
support ring with a loose t is not permissible. In general, thermowells with a support ring are not
recommended within ASME PTC 19.3 TW 2010 and are outside of the scope of the standard.
GB
It is recommended to mount the temperature measuring instrument into the thermowell using a
suitable sealing material to avoid, for example, humidity ingress.
In general, the tip of the thermowell should be placed in the middle third of the pipe, though
the position may dier in special cases. It must be ensured that the measuring element (Pt100,
thermocouple, bimetal, etc.) is completely exposed to the medium and is not shielded by the
ange stubs. If, as a result of a small pipe diameter, this cannot be ensured, a pipe expansion can
be inserted around the measuring point.
Expansion of the pipe diameter
from DN 40 to DN 80

6. Commissioning, operation
Screw-tting thermowells
When using parallel threads, a suitable seal should be used when mounting. Tapered threads
can be sealed by suitable seals or an additional welded seam. The correct tightening torques and
suitable tools (e.g. spanner) should be used.
GB
Weld-tting thermowells
Weld-in thermowells can be mounted into the process directly (pipe or vessel wall) or by using
a welding socket. Make sure that the weld seam is clean and that suitable equipment is used. If
necessary, heat-treat the weld seams.
Thermowells with ange connection
The ange dimensions of the thermowell must match those of the mating ange on the process
side. The seals used must be suitable for the process and the ange geometries (consult the
delivery note). The correct tightening torques and suitable tools (e.g. spanner) should be used
for installation. For thermowells with a collar, make sure that it matches the inner diameter of the
coupling and is supported by it. In the case of an interference collar, they should be adapted to the
inner diameter of the coupling.
Irrespective of the process connection, 3 mounting positions of thermowells in pipes are possible:
■
Right-angled position with respect to the ow (most unfavourable position)
■
Tilted position with respect to the ow (tip inclined towards the ow direction is preferred)

6. Commissioning, operation / 7. Maintenance and cleaning
■
Flow towards the tip in an elbow (most favourable position)
The insertion length and the diameter of the thermowell are dependent on the process conditions,
especially on the ow rate of the measured medium.
The regulations in accordance with VDI/VDE 3511-5, DIN 43772 Appendix 1/2 and the AD Codes
must be observed.
7. Maintenance and cleaning
7.1 Maintenance
In general, thermowells are maintenance-free.
We recommend a visual check of the thermowell for leaks and damages at regular intervals.
Make sure that the seal is in perfect condition!
GB
Repairs should only be carried out by the manufacturer or, following prior consultation, by correspondingly qualied skilled personnel.
7.2 Cleaning
CAUTION!
Wash or clean the dismounted instrument before returning it, in order to protect sta
and the environment from exposure to residual media.
For information on returning the thermowell see chapter "9.2 Return".

WARNING!
Residual media on dismounted thermowells can result in a risk to persons, the
environment and equipment. Take sucient precautionary measures.
9.1 Dismounting
WARNING!
Risk of burns!
Let the instrument cool down suciently before dismounting it!
When dismounting it, there is a risk that dangerously hot pressure media may escape.
Only disconnect thermowells once the system has been depressurised!
