2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
thermowell has been selected in terms of 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 the 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 model TW61 thermowell has been specically
developed for use in sanitary applications.
GB
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.
Improper handling or operation of the instrument outside of its technical specications 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.

4.1 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 sensor without having to open the process.

Model TR22-B: M24 x 1.5 rotatable male nut
GB
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measuring insert can be withdrawn together with the connection head.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.

5. Transport, packaging and storage
5.1 Transport
Check the thermowell for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
GB
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: 0 ... 70 °C
■
Humidity: 35 ... 85 % relative humidity (no condensation)
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
CAUTION!
Before commissioning the thermowell, clean the plant in accordance with the
cleaning specications.
The thermowell must not be bent or altered in order to mount it. The tting 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. using a
pipe clamp) 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 oset (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 97/23/EC 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
■

6. Commissioning, operation / 7. Maintenance and cleaning
Recommended installation for the angular housing design
Concerning the angular housing design it is recommended, to install the sensor horizontally and
not vertically in the pipeline. Consequently the formation of an air pocket during sterilization in the
cupola is avoided.
7. Maintenance and cleaning
GB
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!
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
personnel and the environment from exposure to residual media.
■

Die technischen Spezikationen in dieser Betriebsanleitung sind einzuhalten. Eine unsachgemäße Handhabung oder ein Betreiben des Gerätes außerhalb der technischen Spezikationen
macht die sofortige Stilllegung und Überprüfung durch einen autorisierten WIKA-Servicemitarbeiter erforderlich.
Ansprüche jeglicher Art aufgrund von nicht bestimmungsgemäßer Verwendung sind
ausgeschlossen.
