DANGER!
... identifies hazards due to electrical power. Should the safety instructions not be
observed, there is a risk of serious or fatal injury.
WARNING!
... indicates a potentially dangerous situation that can result in burns, caused by
hot surfaces or liquids, if not avoided.
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate
thermowell has been selected in terms of design and specific 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 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.

2.2 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.
2.3 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, flammable 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.
DANGER!
Make sure that the thermowell is sufficiently earthed.

4. Design and function
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.
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.
