Condition Description
Internal pressure The design of joints, threaded connections and sealing elements has been
executed as a function of the maximum allowable pressure inside the reactor.
Operating temperature The materials used were chosen according to the operating and design
minimum and maximum temperatures. Thermal displacement has been taken
into account to avoid intrinsic stresses and to ensure proper integration
between the instrument and the plant. Specific care has to be taken when the
instrument’s sensing elements are fixed to the plant internals.
Process fluids Dimensions and choice of materials minimize:
• distributed and localized corrosion,
• erosion and abrasion,
• corrosion phenomena due to uncontrolled and unpredictable chemical
reactions.
Specific process fluids analysis is necessary to properly ensure the maximum
operating life of the device, through proper material selection.
Fatigue Cyclic loads during operations are not foreseen.
6 Endress+Hauser
iTHERM MultiSens Flex TMS01 Basic safety instructions
Condition Description
Vibrations The sensing elements can be subjected to vibrations, due to high immersion
lengths from the constraint located in the process connections. This vibrations
can be minimized by properly selecting the route of the sensing element into
the plant, by fixing it on internals by means of accessories like clips and end
tips. The extension neck has been designed for withstanding vibratory loads to
preserve the junction box from cyclic loading, and to avoid the unscrewing of
the threaded components.
Mechanical stress The maximum stress on the measuring device multiplied by a safety factor is
guaranteed to stay below the yielding stress of the material, for every working
condition of the plant.
External environment The junction box (with and without head transmitters), wires, cable glands and
other fittings have been selected to work within the allowed ranges in terms of
external temperature.
2.3 Workplace safety
The external installation area must be free of interferences to avoid any injury during
installation, and to avoid any damage to the measuring device.

3.1 Product design
The multipoint thermometer belongs to a range of modular product configuration for
multipoint temperature detection with a design where subassemblies and components can
be managed individually for easy maintenance and spare part ordering.
It consists of the following main sub-assemblies:
• Insert: Done by a metal sheathed sensing measuring element (thermocouple or
resistance), extension cables and transition bushing. Each insert can be handled as an
individual spare part that is replaceable by untightening its compression fitting installed
onto the process connection. They can be ordered via specific standard product order
codes (e.g. TSC310, TST310) or special codes. For the specific order code please contact
the Endress+Hauser service department.
• Process connection: Represented by an ASME or EN flange, it might be provided with
eyebolts for lifting the device.
• Head: It is composed of a junction box provided with its components such as cable
glands, draining valves, earth screws, terminals, head transmitters, etc.
• Neck: It is designed to support the junction box by components such as supporting rods
and plates or tube extension.
• Additional accessories: Components that can be ordered independently from the
selected product configuration, such as clips, pads, tips, spacers and plates for tag
sensors.
• Thermowells: They are directly welded on the process connection, designed to
guarantee higher degree of mechanical protection and corrosion resistance for each
sensor.
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 are wired into the junction box,
which can be directly mounted or remote as option.

The modular multipoint thermometer is characterized by the following possible main
configurations:
• Linear configuration
The different sensors are aligned along
the straight direction coinciding with the
longitudinal axis of the multipoint
assembly itself (linear multipoint
measurement). This configuration can be
used to install the multipoint either in an
existing thermowell as part of the reactor
or in direct contact with the process.
• 3D distribution configuration
All the inserts, regardless of using the
single insert thermowell protection or not,
can be bent and arranged in a three
dimensional configuration by fixing them
through clips or other equivalent
accessories. This configuration is
commonly used to reach several
measurement points distributed at
different cross sections and levels. Specific
support frames can be provided and
installed on request if they are not already
available on site.

6.2 Connecting the sensor cables
Each sensor is marked with an individual TAG number. As default configuration, all
wires are always connected to the installed transmitters or terminals and generally
checked in house before final shipment.
The wiring is done in consecutive order, which means that the input channel(s) of
transmitter no. 1 are connected to the insert wires starting from insert no. 1. Transmitter
no. 2 is not used until all channels of transmitter no. 1 are fully connected. The wires of
each insert are marked with consecutive numbers starting from 1. If double sensors are
used the internal marking has a suffix to distinguish the two sensors, e.g. 1A and 1B for
double sensors in the same insert or measuring point no. 1.

• A shielded cable is recommended for fieldbus communication. Take the plant grounding
concept into consideration.
• The terminals for connecting the signal cable (1+ and 2-) are protected against reverse
polarity.
• Conductor cross-section:
– Max 2.5 mm2 (14 AWG) for screw terminals

Wiring iTHERM MultiSens Flex TMS01
6.4 Shielding and grounding
For any specific electrical shielding and grounding regarding the transmitter wiring
please refer to the appropriate operating manual of the installed transmitter.
Where applicable, national installation regulations and guidelines must be observed
during the installation! Where there are large differences in potential between the
individual grounding points, only one point of the shielding is connected directly with the
reference ground. In systems without potential equalization, therefore, cable shielding of
fieldbus systems should only be grounded on one side, for example at the supply unit or at
safety barriers.
NOTICE
If the shielding of the cable is grounded at more than one point in systems without
potential matching, power supply frequency equalizing currents can occur that
damage the signal cable or have a serious effect on signal transmission.
In such cases the shielding of the signal cable is to be grounded on only one side, i.e. it
‣
must not be connected to the ground terminal of the housing (terminal head, field
housing). The shield that is not connected should be insulated!
6.5 Degree of protection
In order to fulfil the degree of protection after installation or service, the following points
must be taken into consideration: → 9, 22
• The housing seals must be clean and undamaged before they are replaced in the sealing
rebate. If they are found to be too dry, they should be cleaned or even replaced.
• All housing screws and covers must be tightened.
• The cables used for connection must be of the correct specified outside diameter (e.g.
M20 x 1.5, cable diameter from 0.315 to 0.47 in; 8 to 12 mm).
• Tighten cable gland or NPT fitting.
• Loop the cable or conduit before placing into the entry ("Water sack"). This means that
any moisture that may form cannot enter the gland. Install the device so that the cable
or conduit entries are not facing upwards.
• Entries not used are to be blanked off using the blanking plates provided.
• The protective grommet must not be removed from the NPT fitting.

Neck extension
The neck extension ensures the connection between the flange and the junction box. The
design has been developed to ensure several mounting layouts to deal with possible
obstacles and constraints that can be met in any plant such as the reactor’s infrastructure
(step ways, loading structures, supporting skirts, stairs, etc.) and reactor thermal
insulation. The neck extension design ensures easy access for monitoring and maintaining
inserts and extension cables. It guarantees a high stiffness connection for the junction box
and vibration loads. No closed volumes are present in the neck extension. This avoids the
accumulation of waste and potentially dangerous fluids coming from the environment that
can damage the instrumentation allowing continuous ventilation.
Insert and thermowells
Different insert and thermowell types are available. For any different requirement
that is not described here, please contact the Endress+Hauser sales department.
