Transmitters for mounting in sensor head
SITRANS TH100 two-wire system (Pt100)
■ Overview
■ Application
Used in conjunction with Pt100 resistance thermometers, the
SITRANS TH100 transmitters are ideal for measuring temperatures in all industries. Due to its compact size it can be installed
in the connection head type B (DIN 43729) or larger.
2
The output signal is a direct current from 4 to 20 mA that is proportional to the temperature.
Parameterization is implemented over the PC using the parameterization software SIPROM T and the modem for
SITRANS TH100/TH200. If you already have a "modem for
SITRANS TK" (Article No. 7NG3190-6KB), you can continue using this to parameterize the SITRANS TH100.
Transmitters of the "intrinsically-safe" type of protection can be
installed within potentially explosive atmospheres. The devices
comply with the Directive 94/9/EC (ATEX), as well as FM and
CSA regulations.
■ Function
The SITRANS TH100 dispenses with electrical isolation and universal sensor connection to provide a low-cost alternative for
Pt100 measurements.
Mode of operation
Its extremely compact design makes the SITRANS TH100 ideal
for the retrofitting of measuring points or for the use of analog
transmitters.
The measured signal supplied by a Pt100 resistance thermometer (2, 3 or 4-wire system) is amplified in the input stage. The voltage, which is proportional to the input variable, is then converted
into digital signals by a multiplexer in an analog/digital converter.
They are converted in the microcontroller in accordance with the
sensor characteristics and further parameters (measuring
range, damping, ambient temperature etc.).
The transmitter is available as a non-Ex version as well as for use
in potentially explosive atmospheres.
The signal prepared in this way is converted in a digital/analog
converter into a load-independent direct current of 4 to 20 mA.
For the parameterization, the SIPROM T software is used in combination with the modem for SITRANS TH100/TH200.
An EMC filter protects the input and output circuits against electromagnetic interferences.
■ Benefits
• Two-wire transmitter
• Assembly in connection head type B (DIN 43729) or larger, or
on a standard DIN rail
• Can be programmed, which means that the sensor connection, measuring range, etc. can also be programmed
• Intrinsically-safe version for use in potentially explosive areas

Transmitters for mounting in sensor head
SITRANS TH200 two-wire system, universal
■ Overview
■ Application
SITRANS TH200 transmitters can be used in all industrial sectors. Due to their compact size they can be installed in the connection head type B (DIN 43729) or larger. The following sensors/signal sources can be connected over their universal input
module:
• Resistance thermometers (2, 3 or 4-wire system)
• Thermocouples
• Resistance-based sensors and DC voltage sources
2
The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic.
Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices
comply with the Directive 94/9/EC (ATEX), as well as FM and
CSA regulations.
■ Function
Ultra flexible - with the universal SITRANS TH200 transmitter
• Two-wire devices for 4 to 20 mA
• Mounting in the connection head of the temperature sensor
• Universal input for virtually any type of temperature sensor
• Configurable over PC
■ Benefits
• Compact design
• Flexible mounting and center hole allow you to select your preferred type of installation
• Electrically isolated
• Test sockets for multimeters
• Diagnostics LED (green/red)
• Sensor monitoring
open circuits and short-circuits
• Self-monitoring
• Configuration status stored in EEPROM
• SIL2 (with Order Code C20), SIL2/3 (with C23)
• Expanded diagnostic functions, such as slave pointer, operating hours counter, etc.
• Special characteristic
• Electromagnetic compatibility to EN 61326 and NE21
The SITRANS TH200 is configured over a PC. A USB or RS 232
modem is linked to the output terminals for this purpose. The
configuration data can now be edited using the SIPROM T software tool. The configuration data are then permanently stored in
the non-volatile memory (EEPROM).
Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case
of a sensor short-circuit, the LED flashes red, an internal device
fault is indicated by a steady red light.
The test socket can be used to connect an ammeter at any time
for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop.

The digital accuracy is the accuracy after the analog/digital conversion including linearization and calculation of the measured
value.
An additional error is generated in the output current 4 to 20 mA
as a result of the digital/analog conversion of 0.025 % of the set
span (digital-analog error).
The total error under reference conditions at the analog output is
the sum from the digital error and the digital-analog error (poss.
with the addition of cold junction errors in the case of thermocouple measurements).

Temperature Measurement
Transmitters for mounting in sensor head
SITRANS TH300 two-wire system, universal, HART
■ Overview
■ Application
SITRANS TH300 transmitters can be used in all industrial sectors. Due to their compact size they can be installed in the connection head type B (DIN 43729) or larger. The following sensors/signal sources can be connected over their universal input
module:
• Resistance thermometers (2, 3 or 4-wire system)
• Thermocouples
• Resistance-based sensors and DC voltage sources
The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic, superimposed by the digital HART signal.
Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices
comply with the Directive 94/9/EC (ATEX), as well as FM and
CSA regulations.
■ Function
"HART" to beat - the universal SITRANS TH300 transmitter
• Two-wire devices for 4 to 20 mA, HART
• Mounting in the connection head of the temperature sensor
• Universal input for virtually any type of temperature sensor
• Configurable over HART
The SITRANS TH300 is configured over HART. This can be done
using a handheld communicator or even more conveniently with
a HART modem and the SIMATIC PDM parameterization software. The configuration data are then permanently stored in the
non-volatile memory (EEPROM).
■ Benefits
• Compact design
• Flexible mounting and center hole allow you to select your preferred type of installation
• Electrically isolated
• Test sockets for multimeters
• Diagnostics LED (green/red)
• Sensor monitoring
open circuits and short-circuits
• Self-monitoring
• Configuration status stored in EEPROM
• SIL2 (with Order Code C20), SIL2/3 (with C23)
• Expanded diagnostic functions, such as slave pointer, operating hours counter, etc.
• Special characteristic
• Electromagnetic compatibility to EN 61326 and NE21
Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case
of a sensor short-circuit, the LED flashes red, an internal device
fault is indicated by a steady red light.
The test socket can be used to connect an ammeter at any time
for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop.

The digital accuracy is the accuracy after the analog/digital conversion including linearization and calculation of the measured
value.
An additional error is generated in the output current 4 to 20 mA
as a result of the digital/analog conversion of 0.025 % of the set
span (digital-analog error).
The total error under reference conditions at the analog output is
the sum from the digital error and the digital-analog error (poss.
with the addition of cold junction errors in the case of thermocouple measurements).

■ Function
Features
• Mounting in connection head, type B, to DIN 43729, or larger
• Polarity-neutral bus connection
• 24-bit analog-digital converter for high resolution
• Electrically isolated
• Intrinsically-safe version for use in potentially explosive areas
• Special characteristic
• Sensor redundance
SITRANS TH400 fieldbus transmitters
Versions:
• For FOUNDATION fieldbus
• For PROFIBUS PA
With PROFIBUS PA communication
• Function blocks: 2 x analog
The SITRANS TH400 temperature transmitter is a small field bus
transmitter for mounting in the connection head of form B. Extensive functionality enables the temperature transmitter to be precisely adapted to the plant’s requirements. Operation is very
simple in spite of the numerous setting options. Thanks to its universal concept it can be used in all industries and is easy to integrate in the context of Totally Integrated Automation applications.
Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices
comply with the Directive 94/9/EC (ATEX), as well as FM and
CSA regulations.
With FOUNDATION fieldbus communication
• Function blocks: 2 x analog and 1 x PID
• Functionality: Basic or LAS
Mode of operation
The following function diagram explains the mode of operation
of the transmitter.
The only difference between the two versions of the SITRANS
TH400 (7NG3214-... and 7NG3215-...) is the type of fieldbus
protocol used (PROFIBUS PA or FOUNDATION fieldbus).
Installing SITRANS TH400 in temperature sensors turns them
into complete, bus-capable measuring points; compact - and in
a single device.

Transmitters for rail mounting
SITRANS TR200 two-wire system, universal
■ Overview
■ Application
SITRANS TR200 transmitters can be used in all industrial sectors. Their compact design enables simple mounting on standard DIN rails on-site in protective boxes or in control cabinets.
The following sensors/signal sources can be connected over
their universal input module:
• Resistance thermometers (2, 3 or 4-wire system)
• Thermocouples
• Resistance-based sensors and DC voltage sources
2
The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic.
Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices
comply with the Directive 94/9/EC (ATEX).
■ Function
Ultra flexible - with the universal SITRANS TR200 transmitter
• Two-wire devices for 4 to 20 mA
• Enclosure for rail mounting
• Universal input for virtually any type of temperature sensor
• Configurable over PC

Expanded diagnostic functions, such as slave pointer, operating hours counter, etc.
Special characteristic
Electromagnetic compatibility to EN 61326 and NE21
SIL2 (with Order Code C20), SIL2/3 (with C23)
The SITRANS TR200 is configured over a PC. A USB or RS 232
modem is linked to the output terminals for this purpose. The
configuration data can now be edited using the SIPROM T software tool. The configuration data are then permanently stored in
the non-volatile memory (EEPROM).
Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case
of a sensor short-circuit, the LED flashes red, an internal device
fault is indicated by a steady red light.
The test socket can be used to connect an ammeter at any time
for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop.

The digital accuracy is the accuracy after the analog/digital conversion including linearization and calculation of the measured
value.
An additional error is generated in the output current 4 to 20 mA
as a result of the digital/analog conversion of 0.025 % of the set
span (digital-analog error).
The total error under reference conditions at the analog output is
the sum from the digital error and the digital-analog error (poss.
with the addition of cold junction errors in the case of thermocouple measurements).

Transmitters for rail mounting
SITRANS TR300 two-wire system, universal, HART
■ Overview
■ Application
SITRANS TR300 transmitters can be used in all industrial sectors. Their compact design enables simple mounting on standard DIN rails on-site in protective boxes or in control cabinets.
The following sensors/signal sources can be connected over
their universal input module:
• Resistance thermometers (2, 3 or 4-wire system)
• Thermocouples
• Resistance-based sensors and DC voltage sources
The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic, superimposed by the digital HART signal.
Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices
comply with the Directive 94/9/EC (ATEX).
■ Function
"HART" to beat - the universal SITRANS TR300 transmitter
• Two-wire devices for 4 to 20 mA, HART
• Device for rail mounting
• Universal input for virtually any type of temperature sensor
• Configurable over HART

Special characteristic
Electromagnetic compatibility to EN 61326 and NE21
SIL2 (with Order Code C20), SIL2/3 (with C23)
The SITRANS TR300 is configured over HART. This can be done
using a handheld communicator or even more conveniently with
a HART modem and the SIMATIC PDM parameterization software. The configuration data are then permanently stored in the
non-volatile memory (EEPROM).
Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case
of a sensor short-circuit, the LED flashes red, an internal device
fault is indicated by a steady red light.
The test socket can be used to connect an ammeter at any time
for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop.

The digital accuracy is the accuracy after the analog/digital conversion including linearization and calculation of the measured
value.
An additional error is generated in the output current 4 to 20 mA
as a result of the digital/analog conversion of 0,025 % of the set
span (digital-analog error).
The total error under reference conditions at the analog output is
the sum from the digital error and the digital-analog error (poss.
with the addition of cold junction errors in the case of thermocouple measurements).

The user-friendly transmitters for the control room
The SITRANS TW universal transmitter is a further development
of the service-proven SITRANS T for the 4-wire system in a
mounting rail housing. With numerous new functions it sets new
standards for temperature transmitters.
With its diagnostics and simulation functions the SITRANS TW
provides the necessary insight during commissioning and operation. And using its HART interface the SITRANS TW can be
conveniently adapted with SIMATIC PDM to every measurement
task.
All SITRANS TW control room devices are available in a non-intrinsically safe version as well as in an intrinsically safe version
for use with the most stringent requirements.
■ Application
The SITRANS TW transmitter is a four-wire rail-mounted device
with a universal input circuit for connection to the following sensors and signal sources:
• Resistance thermometer
• Thermocouples
• Resistance-based sensors/potentiometers
• mV sensors
• As special version:
- V sources
- Current sources
The 4-wire rail-mounted SITRANS TW transmitter wire is designed for control room installation. It must not be mounted in potentially explosive atmospheres.
All SITRANS TW control room devices are available in a non-intrinsically safe version as well as in an intrinsically safe version
for use with the most stringent requirements.

The signal output by a resistance-based sensor (two-wire, threewire, four-wire system), voltage source, current source or thermocouple is converted by the analog-to-digital converter (1,
function diagram) into a digital signal. This is evaluated in the microcontroller (2), corrected according to the sensor characteristic, and converted by the digital-to-analog converter (6) into an
output current (0/4 to 20 mA) or output voltage (0/2 to 10 V). The
sensor characteristics as well as the electronics data and the
data for the transmitter parameters are stored in the non-volatile
memory (3).
AC or DC voltages can be used as the power supply (13). Any
terminal connections are possible for the power supply as a result of the bridge rectifier in the power supply unit. The PE conductor is required for safety reasons.
A HART modem or a HART communicator permit parameterization of the transmitter using a protocol according to the HART
specification. The transmitter can be directly parameterized at
the point of measurement via the HART output terminals (10).
The operation indicator (4) identifies a fault-free or faulty operating state of the transmitter. The limit monitor (9) enables the signaling of sensor faults and/or limit violations. In the case of a current output, the current can be checked on a meter connected
to test socket (12).

Siemens FI 01 · 2015 US Edition
The SITRANS TW comes with extensive diagnosis and simulation functions.
Physical values can be defined with the simulation function. It is
thus possible to check the complete signal path from the sensor
input to inside the control system without additional equipment.
The slave pointer functions are used to record the minimum and
maximum of the plant’s process variable.

Standard
The article number structure shown below is used to specify a
fully functioning transmitter. The selection of the operating data
(type of source, measuring range, characteristic etc.) is made
according to the following rules:
• Operating data already set in factory to default values:
The default settings can be obtained from the list of parameterizable operating data (see "Special operating data"). The
presets can be modified by the customer to match the requirements precisely.
• Operating data set on delivery according to customer requirements:
Supplement the Article No. by "-Z" and add the Order code
"Y01". The operating data to be set can be obtained from the
list of parameterize operating data. The Order codes A 7 7 to
K 7 7 for operating data to be set need only be specified in the
order if they deviate from the default setting.
The default setting is used if no Order code is specified for operating data.
The selected parameters are printed on the transmitter's rating
plate.

Transmitters for field mounting
SITRANS TF280 WirelessHART
■ Overview
■ Application
The SITRANS TF280 is a WirelessHART field device for temperature measurement with a Pt100 sensor.
This sensor can be installed directly on the field device, or connected at an offset with a cable connection. On the wireless
communication side, the transmitter supports the WirelessHART
standard. A HART modem can be connected to the transmitter
particularly for initial parameterization. Alternatively the device
can be commissioned comfortably by means of the local pushbuttons w/o any additional handset devices.
2
It can be used in all industries and applications in non-explosive
areas.
■ Design
The SITRANS TF280 has a robust aluminum enclosure and is
suitable for outside use. It conforms with the IP65 safety class.
SITRANS TF280 for flexible and cost-effective temperature measurements
• Supports the WirelessHART standard (HART V 7.1)
• Very high security level for wireless data transmission
• Built-in local user interface (LUI) with 3-button operation
• Optimum representation and readability using graphical display (104 x 80 pixels) with integrated backlight
• Stand-by (deep sleep phase) mode can be turned on and off
with push of a button
• Battery power supply
• Battery life time up to 5 years
• Extend battery life time with HART modem interface which can
be switch off
• Optimized power consumption through new design, and increase in battery life time
• Simple configuration thanks to SIMATIC PDM
• Housing meets IP65 degree of protection
• Supports all Pt100 sensors as per IEC 751/DIN EN 60751
■ Benefits
The SITRANS TF280 is a temperature transmitter that features
WirelessHART as the standard communication interface.
Also available is a wired interface to connect a HART modem:
• Flexible temperature measurement
• Save costs on wiring at difficult installation conditions. Wireless technology offers cost advantages in cases where extensive wiring costs would normally apply.
• It enables additional hitherto unfeasible measuring points,
particularly for monitoring purposes
• Easy installation also on moveable equipment parts
• Enables cost-effective temporary measurements, for example
for process optimizations.
• Optimum solution in addition to wired communication and for
system solutions in process automation
The operation temperature range is -40 to +80 °C
(-40 to +176 °F). Power supply is provided through an integrated
battery, which is available as an accessory. The device is only
approved for operation with this battery.
The antenna features a rotatable joint which can be used for
directional alignment. Wireless signals can thus be optimally
received and transmitted.
A special highlight is the possibility to operate directly on the
device with 3 push buttons. It perfectly matches the strategy of
all new Siemens field devices.
Using the device’s push buttons, it is easy to turn the HART
modem interface of the device on and off. The device can be put
to passive status and reactivated at any time. This helps to
extend the life time of the battery.
The SITRANS TF280 transmitter features a cable gland or a
Pt100 sensor including protective piping.
■ Function
The SITRANS TF280 can join to a WirelessHART network. It can
be parameterized and operated through this network. Measured
process values are transmitted via the network to the
SIEMENS IE/WSN-PA LINK.
Field device data received by the IE/WSN-PA LINK is transmitted
to the connected systems, for example the process control system SIMATIC PCS 7. For an introduction of WirelessHART,
please see the FI 01 catalogue Sec. 8 or
www.siemens.com/wirelesshart.
Detailed information on IE/WSN-PA LINK can be found in the
FI 01 catalogue Sec. 7 or www.siemens.com/wirelesshart.
■ Integration
Connecting to SIMATIC PCS 7
The integration of field devices in SIMATIC PCS 7 and other process control systems can be now done seamlessly and cost-effectively with wireless technology, especially in situations where
high wiring costs may be expected. Of particular interest are
measuring points which are to be added and for which no wiring
is available.
Where larger distances between the IE/WSN-PA LINK and control systems need to be overcome, this connection can also be
implemented on a wireless and cost-effective basis using the
SCALANCE W series of products. Siemens WirelessHART devices operate with optimum coexistence to SCALANCE W family
products.

Transmitter for field mounting/field indicator
SITRANS TF - Transmitter, two-wire system and SITRANS TF - Field indicator for 4 to 20 mA
■ Overview
■ Function
Configuration
The communication capability over the HART protocol V 5.9 of
the SITRANS TF with an integrated SITRANS TH300 permits parameterization using a PC or HART communicator (hand-held
communicator). The SIMATIC PDM makes it easy.
Parameterization is carried out using a PC for SITRANS TF with
the integrated and programmable SITRANS TK. Available for
this purpose are a special modem and the software tool
SIPROM T.
Mode of operation
Mode of operation of SITRANS TF as temperature transmitter
The sensor signal, whether resistance thermometer, thermocouple element or  or mV signal, is amplified and linearized. Sensor and output side are electrically isolated. An internal cold
junction is integrated for measurements with thermocouple elements.
Our field devices for heavy industrial use
• HART, Universal
• 4 to 20 mA, universal
• Field indicator for 4 to 20 mA signals
The temperature transmitter SITRANS TF works where others
feel uncomfortable.
■ Benefits
• Universal use
- as transmitter for resistance thermometer, thermocouple element,  or mV signal
- as field indicator for any 4 to 20 mA signals
• Local sensing of measured values over digital display
• Rugged two-chamber enclosure in die-cast aluminium or
stainless steel
• Degree of protection IP67
• Test terminals for direct read-out of the output signal without
breaking the current loop
• Can be mounted elsewhere if the measuring point
- is hard to access,
- is subject to high temperatures,
- is subject to vibrations from the system,
- or if you want to avoid long neck tubes and/or protective
tubes.
• Can be mounted directly on American-design sensors
• Wide range of approvals for use in potentially explosive atmospheres. "Intrinsically safe, non-sparking and flameproof" type
of protections, for Europe and USA.
• SIL2 (with Order Code C20), SIL2/3 (with C23)
■ Application
SITRANS TF can be used everywhere where temperatures need
to be measured under particularly adverse conditions, or where
a convenient local display is ideal. Which is why users from all
industries have opted for this field device. The rugged enclosure
protects the electronics. The stainless steel model is almost
completely resistant to sea water and other aggressive elements. The inner workings offer high measuring accuracy, universal input and a wide range of diagnostic options.
The device outputs a temperature-linear direct current of 4 to
20 mA. As well as the analog transmission of measured values
from 4 to 20 mA, the HART version also supports digital communication for online diagnostics, measured value transmission
and configuration.
SITRANS TF automatically detects when a sensor should be interrupted or is indicating a short-circuit. The practical test terminals allow direct measurement of 4 to 20 mA signals over an ammeter without interrupting the output current loop.
Mode of operation of SITRANS TF as field indicator
Any 4 to 20 mA signal can be applied to the generous terminal
block. As well as a range of predefined measurement units, the
adjustable indicator also supports the input of customized units.
This means that any 4 to 20 mA signal can be represented as
any type of unit, e.g. pressure, flow rate, filling level or temperature.

The digital accuracy is the accuracy after the analog/digital conversion including linearization and calculation of the measured
value.
An additional error is generated in the output current 4 to 20 mA
as a result of the digital/analog conversion of 0.025 % of the set
span (digital-analog error).
The total error under reference conditions at the analog output is
the sum from the digital error and the digital-analog error (poss.
with the addition of cold junction errors in the case of thermocouple measurements).

Transmitters for field mounting
SITRANS TF fieldbus transmitter
■ Overview
■ Application
The SITRANS TF can be used everywhere where temperatures
need to be measured under particularly harsh conditions. Which
is why users from all industries have opted for this field device.
2
The rugged enclosure protects the electronics. The stainless
steel model is almost completely resistant to sea water and other
aggressive elements.
The inner workings offer high measuring accuracy, universal input and a wide range of diagnostic options.
■ Function
Our field devices for heavy industrial use
• FOUNDATION fieldbus
• PROFIBUS PA
The SITRANS TF temperature transmitter works where others
can’t cope.
■ Benefits
• For universal use as a transmitter for resistance thermometers,
thermocouple elements,  or mV signals
• Rugged two-chamber enclosure in die-cast aluminium or
stainless steel
• Degree of protection IP67
• Can be mounted elsewhere if the measuring point
- is hard to access,
- is subject to high temperatures,
- is subject to vibrations from the system,
- or if you want to avoid long neck tubes and/or protective
tubes.
• Can be mounted directly on American-design sensors
• Wide range of approvals for use in potentially explosive atmospheres. "Intrinsically safe, non-sparking and flameproof" type
of protection, for Europe and USA
- Resistance thermometer
- Thermocouple
- mV sensor
- Resistance-based sensors
Mode of operation
The following function diagram explains the mode of operation
of the transmitter.
The only difference between the two versions of the SITRANS TF
(7NG3137-... and 7NG3138-...) is the type of field bus protocol
used (PROFIBUS PA or FOUNDATION fieldbus).

The basic sensors are:
• Resistance thermometers:
Temperature measurement is based on the temperature dependency of the installed measuring resistor.
• Thermocouples:
Temperature measurement is based on the Seebeck effect.
A thermocouple which subjected to a temperature drop produces thermoelectric voltage that can be measured.
Transmitters:

Technical description
■ Configuration
Components: Process connections
Step down threaded well assemblies
Flanges
2
The different properties of the flanges are as follows:
• Standard series EN 1092, ASME 16.5,..
• Nominal pressure
• Nominal diameter
• Sealing face
This information is stamped into the flange, as well as the material code and batch number for "3.1 Material".
Components: Thermowell
Thermowells fulfill two basic functions:
• They protect the measuring insert from aggressive media
• They make it possible to replace units during ongoing operations
This catalog is limited to the standard versions. Special versions
are available on request. The large number of available types
can be classified as follows:
• Barstock thermowells
Where process loads are too high, or where thermowells with
welded seams are not allowed, deep hole drilled barstock
thermowells are used. Form 4 thermowells (as per DIN 43772)
are very popular in this area. This thermowell type replaces
the D1-D5 types of the predecessor standard DIN 43763.
Components: Extension (neck tube)
The extension is the section from the lower edge of the connection head to the fixed point of the process connection or thermowell. There is a variety of terms for this components, e.g. neck
tube. For this reason the term extension has been selected as a
standardized term for the different designs. Function is the deciding factor:
• Thermal decoupling of connection head from process temperature see image page 2/87
• Installation of connection head over existing insulation
• Simple standardization of measuring inserts: In general, the
length of the extension may be freely selected. However, when
using standardized insertion lengths, the option "Extension as
per DIN 43 772" is recommended. This ensures that measuring inserts which are quickly available can be used. In case of
special lengths, it is possible to standardize the measuring insert length through a clever combination with the respective
special extension length. This allows customers to optimize
their costs in purchasing and logistics.
• In the case of American-designed sensors, the extension also
takes the spring load of the measuring unit.
• Depending on the design, the extension can also be used to
achieve an alignment of the connection head.
• Barstock thermowells:
Extension and thermowell of two components which are
welded together. The process connection is attached to the
thermowell (= multi-piece protective armature).

Components: Connection head
Connection head
The connection head protects the connection department. The
connection head features sufficient room for mounting a clamping base or transmitter.
2
Different connection heads are used depending on the application and preference.
Components: Measuring insert
Measuring inserts feature a large spring range. These measuring inserts are ideal for use with NPT threads with the typical
loose tolerances. In this configuration, the extension function is
partially or fully integrated (nipple-union-nipple). Moreover it is
also possible to directly attach field devices, e.g. SITRANS TF.
Components: Transmitters
SITRANS TH head transmitters process the weak non-linear sensor signals and transmit a stable and temperature-linear standard signal, thereby minimizing sensor signal disruptions.
The transmitters permanently monitor the temperature sensors
and transmit diagnostic data to superordinate systems.
Because of the low energy feed of the SITRANS TH head transmitters, self-heating of the temperature sensors can be maintained at minimal levels.
The electrical isolation and integrated cold junction ensure that
temperature sensors with thermocouples provide reliable measurements at a low cost.

Measuring technology: Sensor elements
Measuring technology: Measuring accuracy
The diverse application spectrum for industrial temperature
measuring technology requires different sensor technologies.
Resistance thermometer
Resistance thermometer
Sensor elements made of other basic materials with different
nominal resistances or different underlying standards are available on request. Resistance thermometers can be classified as
follows:
• Basic design:
The sensor element is built with thin layer technology. The
resistance material is applied in the form of a thin layer on a
ceramic carrier material.
• Versions featuring increased vibration-resistance:
In addition to the basic design, the vibration resistance is
improved through extra measures.
• Versions with expanded measuring range:
Elements in wire-wound design. The wire winding is embedded in a ceramic body.
Thermocouples
Other thermocouples based on other thermo couples or underlying standards are available upon request.
The most common base metal thermocouples include:
• Type K (NiCr-Ni) more stable than type J, but drifts in upper
range.
• Type J (Fe-CuNi) narrow application band
Measuring technology: Measuring range
The measuring range describes the temperature limits within
which the thermometer can be used in a way that is meaningful
for measurement purposes. Depending on the loads present,
the thermowell materials and the desired accuracy levels, the
actual application range for the thermometer may be smaller.

Measuring technology: Response times
Thermocouples
Response time describes the speed of the measurement system
in the case of a temperature change, and is typically indicated
as T0.5 or T0.9. The values indicate the time in which a measured value has increased to 50% or 90% of the actual temperature increase.
Typical values as per EN 60751 in water at 0.4m/s can be found
in the following table.
The main variables which affect response time are as follows:
• Ideal thermowell geometry includes:
- smallest possible material at the tip
- use of conductive material
• Thermal connection of measuring insert to thermowell:
Due to the optimized design of the Siemens inserts (small gap
width, spring system), they feature very good response behavior. Because of the good fit, additional contact materials
are not usually required except in certain applications e.g. attachment of a surface sensor.

In the case of resistance thermometers, the type of sensor connection directly affects the level of accuracy:
Two-wire system
The resistance of sensor lines are included in the measurement
result as an error. Adjustments are recommended in this case.
Pt100
Immersion depth/contact with media
Ambient conditions (temperature/climate/insulation) and the design of the thermowell, process connection and piping result in
so-called "heat transmission errors".
To prevent such an error, the submersion depth and diameter of
the thermowell tip will be defined. The temperature-sensitive
length (TSL) of the thermowell must also be taken into account.
The following rule of thumb can be used:
• Water
Submersion depth  TSL + 5 x Ø of thermowell
• Air
Submersion depth  TSL + 10 ... 15 x Ø of thermowell
• Recommendations
- Select largest possible submersion depth
- Select measuring location with higher flow velocity
- Thermal insulation for outer thermometer components
- Smallest possible surface for outer components
- Insertion in pipe bends
- Direct measurements without additional thermowell if no suitable solution can be found using other measures.
Pt100 Two-wire system

Line resistance is not included in the measurement result. Requirements: all terminal and line resistances (corrosion) are at
the same level, and terminals are at the same temperature level.

Siemens measuring inserts can be used to implement all types
of connections for 1 x Pt100 devices. In the case of 2 x Pt100 versions, two- and three-wire systems are also possible. For measurement-related reasons, we always recommend a 1 x four-wire
or 2 x 3-wire connection.

Please note that guidance values may change due to local conditions. Please consider these potential changes particularly
with respect to explosion protection.
Also note that the accuracy of the transmitter also depends on
the temperature in the connection head.
Process connection/Thermowell
When selecting a process connection, the process parameters
sometimes only allow a specific technology. In addition, regional
standard-related and customer-specific requirements must be
abserved. The range of products therefore includes a broad selection of standard connections.
In the case of redesigned or newly designed facilities, it is possible to achieve cost savings by implementing various measures:
• Use of standard lengths through clever selection of screw,
weld or flange sockets
• Moveable compression fittings
Process load
Because of the large variety of possible applications and variables, it is not possible to make general binding statements regarding the resilience of components which comes into contact
with media. The load diagrams below can be used for common
applications. However, where operating conditions vary significantly, please contact our technical support team.

The temperature resistance of a material for process connections and thermowells also limits the application area of the temperature sensor. The temperature range indicated on the type
plate always refers to the measuring insert, not the material
which comes into contact with media. Two aspects must be considered when assessing temperature stability:
• What maximum temperature may the material reach without a
load?
• What is the behavior under load?

Technical description
Thermowell calculation
Properly applied load diagrams will provide a sufficient degree
of safety for the most common thermowell configurations.
2
However, there are cases in which operating conditions deviate
too greatly from standard parameters. In this case, a customized
thermowell calculation may be required.
Another reason for doing this calculation is the fact that flowing
media can create turbulence at the tip of the thermowell under
certain conditions. The thermowell will then vibrate and may
even be destroyed if not configured correctly. This is the most
frequent cause of thermowell bailure.
SIEMENS offers the two recognized methods for calculating the
thermowell:
• DIN/Dittrich method
• ASME/Murdock method
This method also takes into account turbulence formation on
a mathematical level.
Both methods provide a high degree of safety with regard to
thermowell configuration, however, they do not provide a guarantee against breakdowns.

Where cost-intensive materials are used with flange thermowells, cost savings can be achieved by using a so-called flanged wheel.
A thin disc of the material which comes into contact with media is applied prior to the flange (ordinary stainless steel).

Technical description
Vibration resistance of measuring insert, cable sensor
Similar to the thermowell, inner (Karman vortices) and outer
(plant) vibrations also affect the measuring insert. For this reason, a special assembly of measurement elements is required.
Other than a few exceptions for cable and compact thermometers, Siemens only produces sensors based on a mineral-insulated cable. Together with precautions taken when installing the
measuring element, the Siemens basic version already exceeds
EN 60751 by more than a factor of 3. Pursuant to the measurement methods of this standard, the following values are obtained
(tip-tip):
• 10 g: Basic version and expanded measuring range
• 60 g: Increased vibration-resistance and thermocouple
Bending ability of measuring insert/cable sensor
All Siemens measuring inserts SITRANS TSinsert are made with
a mineral-insulated cable (MIC). The same applies to a portion
of the cable and compact thermometer. In addition to the properties already described, another advantage of the MIC is its
bending ability. This makes it possible to install these thermometers even in difficult to access areas. Please ensure that you are
not below the following bending radius:
Ø MIC [mm (inch)]
Rmin = 4x Ø MIC [mm (inch)]
3 (0.12)
12 (0.48)
6 (0.24)
24 (0.95)
2
Where a smaller bending radius is required due to installation
conditions, subsequent testing of the insulation resistance is
recommended.
Electrical stability
Insulation resistance
The insulation resistance between each measuring circuit and
the fitting is tested at a voltage of 500 V DC at room temperature.
Riso  100 M
Due to the property of the mineral-insulated cable, the insulation
resistance decreases as temperature increases. Because of the
special production method, it is, however, possible to achieve
very good values even at high temperatures.
Line resistance
When connected to two-wire systems, the line resistance is included in the measurement result. The following rule of thumb
can be used:
•  Measuring insert 3 mm (0.12 inch) 5 /m or 12.8 °C
(55.04 °F)
•  Measuring insert 6 mm (0.24 in) 2.8 /m or 44.78 (44.78 )
For this reason a connection to three- or four-wire systems is
highly recommended.

Circuit diagram for thermocouple
Where thermocouples are used, the use of head transmitters offers particular advantages: The cold junction is already integrated into the universal transmitter. There is no need for expensive thermo or extension cable. This also removes a number of
possible error sources. The weak millivolt signal of the thermocouple is already converted into a stable and temperature-linear
DC or bus signal on site. This drastically reduces the effects of
electromagnetic factors on the measurement result.
If a head transmitter is not installed, the sensor feed line consists
either of the appropriate thermo or extension leads. The thermo
line is made from the thermo material of the relevant thermocouple, while the extension lead uses a cost-effective substitute material. The extension cable behaves similar to a thermo line at an
electrical level, within a limited temperature range of up to
200°C.
