iTHERM MultiSens Slim TMS21
Function and system design
Measuring principle Thermocouples (TC)
Thermocouples are comparatively simple, robust temperature sensors which use the Seebeck effect
for temperature measurement: if two electrical conductors made of different materials are connected
at a point, a weak electrical voltage can be measured between the two open conductor ends if the
conductors are subjected to a thermal gradient. This voltage is called thermoelectric voltage or
electromotive force (emf.). Its magnitude depends on the type of conducting materials and the
temperature difference between the "measuring point" (the junction of the two conductors) and the
"cold junction" (the open conductor ends). Accordingly, thermocouples primarily only measure
differences in temperature. The absolute temperature at the measuring point can be determined
from these if the associated temperature at the cold junction is known or is measured separately and
compensated for. The material combinations and associated thermoelectric voltage/temperature
characteristics of the most common types of thermocouple are standardized in the IEC 60584 and
ASTM E230/ANSI MC96.1 standards.
Measuring system
Endress+Hauser offers a complete portfolio of optimized components for the temperature measuring
point – everything you need for the seamless integration of the measuring point into the overall
facility.
This includes:
• Power supply unit/active barrier
• Configuration units
• Overvoltage protection

Measuring Point' (FA00016K/09)

4 Active barrier RN221N (24 VDC, 30 mA) that has a galvanically isolated output for supplying voltage to loop-
powered transmitters. The universal power supply works with an input supply voltage of 20 to 250 V DC/AC;
50/60 Hz, which means that it can be used in all international power grids.
5 Surge arrester modules HAW562Z for protection of signal lines and components in hazardous areas, e.g.
4 to 20 mA- , PROFIBUS® PA, FOUNDATION Fieldbus™ signal lines. More information on this can be found
in the Technical Information → 24
6 Remote junction box available as an option with built-in transmitter for 4 to 20 mA, PROFIBUS® PA,
FOUNDATION Fieldbus™ signal lines.
7 Mounted multipoint thermometer in a locally existing tube.
The new iTHERM MultiSens Slim has an innovative design able to allow a wide variety of options in
terms of materials selection, sizes and number of measuring points. In addition a portfolio of
selectable accessories (not in contact with the process) individually managed for easy maintenance
and spare part ordering, like adapters and conduits, is available.
It consists of five main sub-assemblies:
• Extension: It consists of a threaded bushing for sealed electrical connections, matched to an
adapter from which flexible conduit containing the extension cables.
• Main bushing and reinforcing sleeve:
• Process connection: The process connection is represented by a compression fitting. When
necessary, an ASME or EN flange is available on request.
Other standards or connection types can be offered on request. The flanges are provided with
welded compression fitting for process tightness.
• Thermowell: with or without reinforcing sleeve
• Insert: Composed of metal sheathed sensing measuring elements (thermocouples), extension
cable and transition bushing. The sensing elements are mounted inside a small diameter pipe
thermowell.
Part of the thermowell can be a flexible hose to guarantee additional bendability into the process
of the sensing probe, to ensure internal routing in the case of misalignment between installation
nozzle and the distribution of measuring points.
• Additional accessories: Components that can be ordered independently from the selected product
configuration, such as junction boxes and transmitters, able to fit with all the already installed
customer devices.

Design Description
In general, the system measures the temperature profile inside the process environment by means of
many sensors, jointed to a suitable process connection which ensures the right tightness levels.
Externally, the extension cables (protected by the conduit) are wired into the junction box, which can
be installed integrated or remote (optional).
Some of the options listed in this document may not be available in your country. Please contact
your local Endress+Hauser representative.

Output signal
Family of temperature transmitters
Generally, the measured value can be transmitted in one of two ways:
• Directly-wired sensors - sensor measured values forwarded without a transmitter.
• Via all common protocols by selecting an appropriate Endress+Hauser iTEMP temperature
transmitter. All the transmitters listed below are mounted directly in the junction box and wired
with the sensory mechanism.
Thermometers fitted with iTEMP transmitters are an installation-ready complete solution to
improve temperature measurement by significantly increasing accuracy and reliability, when
compared to direct wired sensors, as well as reducing both wiring and maintenance costs.
PC programmable head transmitters
They offer a high degree of flexibility, thereby supporting universal application with low inventory
storage. The iTEMP transmitters can be configured quickly and easily at a PC. Endress+Hauser offers
free configuration software which can be downloaded from the Endress+Hauser Website. More
information can be found in the Technical Information.
HART® programmable head transmitters
The transmitter is a 2-wire device with one or two measuring inputs and one analog output. The
device not only transfers converted signals from resistance thermometers and thermocouples, it also
transfers resistance and voltage signals using HART® communication. It can be installed as an
intrinsically safe apparatus in Zone 1 hazardous areas and is used for instrumentation in the
terminal head (flat face) as per DIN EN 50446. Swift and easy operation, visualization and
maintenance by PC using operating software, Simatic PDM or AMS. For more information, see the
Technical Information.
PROFIBUS® PA head transmitters
Universally programmable head transmitter with PROFIBUS® PA communication. Conversion of
various input signals into digital output signals. High accuracy over the complete ambient
temperature range. Swift and easy operation, visualization and maintenance using a PC directly from
the control panel, e. g. using operating software, Simatic PDM or AMS. For more information, see
the Technical Information.
FOUNDATION Fieldbus™ head transmitters
Universally programmable head transmitter with FOUNDATION Fieldbus™ communication.
Conversion of various input signals into digital output signals. High accuracy over the complete
ambient temperature range. Swift and easy operation, visualization and maintenance using a PC
directly from the control panel, e.g. using operating software such as ControlCare from Endress
+Hauser or NI Configurator from National Instruments. For more information, see the Technical
Information.
Advantages of the iTEMP transmitters:
• Dual or single sensor input (optionally for certain transmitters)
• Unsurpassed reliability, accuracy and long-term stability in critical processes
• Mathematical functions
• Monitoring of the thermometer drift, sensor backup functionality, sensor diagnostic functions
• Sensor-transmitter matching for dual sensor input transmitter, based on Callendar/Van Dusen
