3.1 Equipment architecture
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.
The temperature probe-only version consists of many sub-assemblies:
• Insert
• Rope
• Weight
• Process connection
• Neck (see below for a more detailed description)
In general the instrument measures the temperature profile inside the process
environment by means of many sensors wrapped around a rope, jointed to a suitable
process connection which ensures the right tightness level.
The temperature probe + diagnostic version combines the temperature probe with a head
transmitter, which is available with enhanced accuracy and reliability compared to directly
wired sensors. Output communication protocols available are: Analog output 4 to 20 mA,
HART®, PROFIBUS® PA, FOUNDATION Fieldbus™. Externally the extension cables are
wired into the junction box, which can be directly mounted or remotely as an option.

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. In case of remote junction box it might be
that the following steps have to be executed for the multipoint side aswell.
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.

iTHERM MultiSens Bundle TMS31 Electrical connection
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
The device components can be conform to the requirements up to IP 68 ingress protection.
In order to fulfil the degree of protection after installation or service, the following points
must be taken into consideration: → 9, 21
• 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.
• 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.

11.3.5 Calibration
Calibration is a service that can be performed on each individual insert, either in order
phase, or after multipoint installation.
When calibration shall be performed once the multipoint is installed, please contact
the Endress+Hauser service to get full support. Together with the Endress +Hauser
service any further activity can be organised to achieve the calibration of the target
sensor. In any case it is forbidden to unscrew any threaded component on the process
connection under operating conditions = running process.
Calibration involves comparing the measured values of the sensing elements of the
multipoint inserts (DUT device under test) with those of a more precise calibration
standard using a defined and reproducible measurement method. The aim is to determine
the deviation of the DUT measured values from the true value of the measured variable.
Two different methods are used for the inserts:
• Calibration at fixed-point temperatures, e.g. at the freezing point of water at 0 °C (32 °F).
• Calibration compared against a precise reference thermometer.
Evaluation of inserts
If a calibration with an acceptable uncertainty of measurement and transferable
measurement results is not possible, Endress+Hauser offers an insert evaluation
measurement service, if technically feasible.

degree of freedom to the rope system allowing movements during filling and emptying
operations. This guarantees low stresses (no extra tensioning) on the rope due to possible
lateral force acting on it, therefore a lateral sag of 30cm per 10m rope length is
recommended. The transition between the inserts and the extension cable is obtained by
the usage of compression fittings, ensuring the declared IP degree protection.

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 storage tank
infrastructure (step ways, loading structures, stairs, etc.) and an eventual thermal
insulation. The neck extension design allows easy access for monitoring extension cables.
It guarantees a high stiffness connection for the junction box and vibration loads. No
closed volumes are present in the neck extension (not for tube neck design). This avoids
the accumulation of waste and potentially dangerous fluids coming from the environment
that can damage the instrumentation allowing continuous ventilation.
