Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit:
https://www.siemens.com/industrialsecurity
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customer’s exposure
to cyber threats.

3.2 Application
Resistance thermometers or thermocouples can be used for temperature measurement.
The temperature sensors of the SITRANS TS product family are used for measuring
temperatures in industrial plants.
Depending on the specifications, sensors can be combined with different connection heads,
extension tubes, and process connections. This makes the sensors suitable for a variety of
process engineering applications, in the following sectors:
● Petrochemical industry
● Pharmaceuticals industry
● Biotechnology
● Food production
Two different measuring principles are used for measuring temperatures.
● With resistance thermometers, the temperature is measured as a change in resistance.
Resistance thermometers, also called Resistance Temperature Devices (RTD), contain
sensor elements, like the Pt100 sensor elements in accordance with IEC 60751.
● With thermocouples, the temperature is the change in voltage (Seebeck effect). The
thermocouples are in accordance with IEC 584/DIN EN 60584.

The maximum permissible operating pressure depends on the device version, pressure
limit and temperature rating. The device can be damaged if the operating pressure is
exceeded. Hot, toxic and corrosive process media could be released.
Ensure that maximum permissible operating pressure of the device is not exceeded. Refer
to the information on the nameplate and/or in Technical data (Page 45).
Risk of injury or poisoning.
In case of improper mounting, hot, toxic, and corrosive process media could be released at
the connections.
• Ensure that connecting parts (such as flange gaskets and bolts) are suitable for
connection and process media.

• Use gasket between device extension and protective tube only once.
Risk of explosion in hazardous areas.
• Ensure sufficient tightness at the process connection.
Risk of burns resulting from surface temperatures above 65 °C (149 °F).
• Take appropriate protective measures, for example contact protection.
• Make sure that protective measures do not cause the maximum permissible ambient
temperature to be exceeded. Refer to the information in Technical data (Page 45).
Damage to device by severe external stresses and loads (e.g. thermal expansion or pipe
tension). Process media can be released.
• Prevent severe external stresses and loads from acting on the device.
Especially with the stainless steel housing version of TS500, use short extensions or
external supports when used in a high vibration area.
When TS100/200 sensors are installed in a high vibrating area, use also external supports
to fix the probe stem: the unsupported length must not exceed 150 mm and the free end
must not exceed 100 mm.

4.1 Basic safety notes
The thermowell is affected by the static, dynamic and chemical load from the process
parameters, e.g. static and dynamic load, flow induced vortexes. This has influence to the
shape of the thermometer, stem diameter and insertion length.
Ensure that the applicable and relevant directives and standards are respected, e.g. ASME
PTC 19.3, DIN43772 Annex 1-2, AD-directive, VDI/VDE 3511-5.
In critical applications, a thermowell stress calculation according ASME PTC 19.3-TW2016
or Dittrich/Klotter-method is recommended as an engineering service.
Protective tubes that are not suitable for the process or application in question can rupture
and result in serious damage to property and personal injuries.
• Make sure that the protective tube is suitable for the respective mounting method and
application. If necessary, check the selection and order data of your protective tube.
Danger of explosion in hazardous areas if electrostatic charges develop, for example, in
strong airflows in close proximity to belt conveyors.
• Avoid electrostatic charge at the plastic head type BM0 when defining the installation
site.
To reach IP54 with a plastic head type BM0, make sure that the mounting angle is in the
Figure 4-1 Mounting angle of plastic head type BM0
Do not unscrew the device housing from the mounted parts with NPT threaded connection.
The device can be damaged, destroyed, or its functionality impaired through improper
mounting.
• Before installing, ensure there is no visible damage to the device.
• Make sure that process connectors are clean, and suitable gaskets and glands are
used.
• Mount the device using suitable tools. Refer to the information in Technical data
(Page 45) for installation torque requirements.
• Avoid temperature or mechanical shocks during mounting.
• Avoid excessive force or damaging of the on-site mechanical connections.
• Do not deform or adapt the thermowells.
• The use of additive seal or sealant (not in scope of delivery) is recommended between
sensor and thermowell.
• Thermowells from carbon steel are protected against corrosion. Clean the thermowell
before mounting to avoid poisoning of the sensor and mounting problems.
Damage to device if the enclosure is open or not properly closed. The degree of protection
specified on the nameplate is no longer guaranteed.

Procedure
4.2 Install
Prior to mounting, make sure that the device is appropriately applied for the process
connection, media compatibility, temperature resistance and measuring range. See chapter
Technical data (Page 45).
1. Prevent faults caused by heat dissipation in non-representative placings by observing the
following rules:
2. Select an optimal immersion depth. Estimate the immersion depth using the formulas in
Table 8-16 Estimation of immersion depth (Page 57).
If the flow rate allows, sensor placing between 1/3 and 1/2 of the pipe diameter is
recommended.
3. If the process load on the thermowell allows the exposition, select a measurement
location with a high flow rate.
4. Ensure sufficient thermal insulation of the external components of the thermometer.
5. Ensure that external parts have as small surfaces as possible.
6. Select the optimum mounting position for the process in question.
7. With small pipe diameters, mount the sensors upstream at an angle ③ or upstream in a

8. Use required torque values between device extension and protective tube as in Table 814 Torque values between device extension and protective tube (Page 56).
– If customer adjustments are necessary (M24 connections only), use required torque
values between device head and extension as in Table 8-15 Torque values between
device head and extension (Page 56).
– For SITRANS TS500 barstock version (only European portfolio 7MC752..) without
flange (type 4), use required torque values to complete the mounting of the device
extension to the protective tube as in Table 8-14 Torque values between device
extension and protective tube (Page 56).
The following risks may result from incorrect disassembly:
- Injury through electric shock
- Risk through emerging media when connected to the process
- Risk of explosion in hazardous area
In order to disassemble correctly, observe the following:
• Before starting work, make sure that you have switched off all physical variables such
as pressure, temperature, electricity etc. or that they have a harmless value.
• If the device contains hazardous media, it must be emptied prior to disassembly. Make
sure that no environmentally hazardous media are released.
• Secure the remaining connections so that no damage can result if the process is started
unintentionally.
