2.1 Description
The model TW61 thermowell is used to adapt thermometers and measuring inserts to the
process and protects the sensor against harsh process conditions. Furthermore, it enables
the removal of the temperature probe without having to open the process.
To integrate it into the process, the thermowell is directly orbitally welded into a pipeline. The
connection ends are smooth and prepared for orbital welding.
In combination with a resistance thermometer, the rotatable threaded connection of the
connection head or the display can be loosened and turned to the desired orientation.
The measuring insert can be withdrawn together with the connection head. In this way,
it is possible to calibrate the entire measuring chain (sensor, transmitter if applicable,
connection cable) on site, without having to disconnect the electrical connection. In addition
this avoids having to open the process, and thus the risk of contamination is minimised.
The thermowell is not piggable.

3. Safety
Information
... points out useful tips, recommendations and information for efficient and
trouble-free operation.
3.2 Intended use
Thermowells are used to protect temperature probes from the process conditions.
Furthermore, thermowells enable the removal of the temperature probe 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 model TW61
thermowell has been specifically developed for use in sanitary applications.
The thermowell 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 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.
3.3 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient
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 qualifications described below.
▶
Keep unqualified 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-specific 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
media.

4. Transport, packaging and storage
4.1 Transport
Check the thermowell for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
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
■
Humidity: 35 ... 85 % r.h. (non-condensing)
WARNING!
Physical injuries and damage to property and the environment through
residual media
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.
▶
Wash or clean the dismounted instrument, in order to protect persons and the
environment from exposure to residual media.

5. Commissioning, operation
Thermowells are delivered free from oil and grease (exception: carbon steels). Depending
on the application, the end user must check whether additional cleaning is required before
installation.
The thermowell must not be bent or altered in order to mount it. The fitting should be carried
out such that there can be no damage to the thermowell as a result of the plant operation or
the operator. If necessary, one of the thermowell/pipeline mountings mentioned below (e.g.
with pipe clamps) will be required. In particular, the neck should be secured by appropriate
methods against bending.
Version for orbital welding
In the orbital welding version, the TW61 is directly welded into the pipeline. Weld the
thermowell centered, without axial offset (without irregularities), orbitally in the pipeline. The
weld joint should therefore be made with appropriate care and in line with the applicable
and accredited welding procedures and tested. Likewise, the requirements of the pressure
equipment directive should be followed.
For general information on the design of a hygienic weld, we recommend the following
documents (among others):
■
EHEDG guideline 35 - Welding of stainless steel tubing in the food industry
■
EHEDG guideline 9 - Welding stainless steel to meet hygienic requirements
■
EHEDG guideline 8 - Hygienic Design principles, 6.3
Recommended installation for the angular housing design
Concerning the angular housing design it is recommended, to install the probe horizontally
and not vertically in the pipeline. Consequently the formation of an air pocket during
sterilisation in the cupola is avoided.

6. Additional notes for instruments with EHEDG and 3-A
6.1 Mounting instructions
Observe the following instructions, especially for EHEDG certified and 3-A conform
instruments.
■
Mount the electrical thermometer, including the thermowell, with minimal dead space
and able to be cleaned easily.
■
Installation position of the thermowell should be designed to be self-draining.
■
The mounting position must not form a draining point or cause a basin to be formed.
6.2 Cleaning in place (CIP) cleaning process
■
Only use cleaning agents which are suitable for the seals used.
■
Cleaning agents must not be abrasive nor corrosively attack the materials of the wetted
parts.
■
Avoid thermal shocks or fast changes in the temperature. The temperature difference
between the cleaning agent and rinsing with clear water should be as low as possible.
Negative example: Cleaning with 80 °C and rinsing at +4 °C with clear water.
7. Faults
CAUTION!
Physical injuries and damage to property and the environment
If faults cannot be eliminated by means of the listed measures, the instrument
must be taken out of operation immediately.
▶
Contact the manufacturer.

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!
Repairs should only be carried out by the manufacturer or, following prior consultation, by
correspondingly qualified skilled personnel.
8.2 Cleaning
CAUTION!
Physical injuries and damage to property and the environment
Improper cleaning may lead to physical injuries and damage to property and the
environment. Residual media in the dismounted instrument can result in a risk to
persons, the environment and equipment.
▶
Carry out the cleaning process as described below.
1. Clean the instrument with a moist cloth.

For information on returning the instrument see chapter 9.2 “Return”.
9. Dismounting, return and disposal
WARNING!
Physical injuries and damage to property and the environment through
residual media
Residual media in the dismounted thermowell can result in a risk to persons, the
environment and equipment.
▶
Observe the information in the material safety data sheet for the
corresponding medium.
▶
Wash or clean the dismounted instrument, in order to protect persons and the
environment from exposure to residual media.
9.1 Dismounting
WARNING!
Risk of burns
During dismounting there is a risk of dangerously hot media escaping.
▶
Let the instrument cool down sufficiently before dismounting it!
Only disconnect thermowells once the system has been depressurised!
9.2 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.
When returning the instrument, use the original packaging or a suitable transport
packaging.
To avoid damage:
1. Wrap the instrument in an antistatic plastic film.
2. Place the instrument, along with the shock-absorbent material, in the packaging.
Place shock-absorbent material evenly on all sides of the transport packaging.
3. If possible, place a bag containing a desiccant inside the packaging.
4. Label the shipment as carriage of a highly sensitive measuring instrument.
