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.
Resistance thermometer (RTD)
These resistance thermometers use a Pt100 temperature sensor according to IEC 60751. The
temperature sensor is a temperature-sensitive platinum resistor with a resistance of 100 Ω at
0 °C (32 °F) and a temperature coefficient α = 0.003851 °C-1.
There are generally two different kinds of platinum resistance thermometers:
• Wire wound (WW): Here, a double coil of fine, high-purity platinum wire is located in a ceramic
support. This is then sealed top and bottom with a ceramic protective layer. Such resistance
thermometers not only facilitate very reproducible measurements but also offer good long-term
stability of the resistance/temperature characteristic within temperature ranges up to
600 °C (1 112 °F). This type of sensor is relatively large in size and it is comparatively sensitive to
vibrations.
• Thin film platinum resistance thermometers (TF): A very thin, ultrapure platinum layer,
approx. 1 μm thick, is vaporized in a vacuum on a ceramic substrate and then structured
photolithographically. The platinum conductor paths formed in this way create the measuring
resistance. Additional covering and passivation layers are applied and reliably protect the thin
platinum layer from contamination and oxidation, even at high temperatures. The primary
advantages of thin film temperature sensors over wire wound versions are their smaller sizes and
better vibration resistance. A relatively low principle-based deviation of the resistance/
temperature characteristic from the standard characteristic of IEC 60751 can frequently be
observed among TF sensors at high temperatures. As a result, the tight limit values of tolerance
category A as per IEC 60751 can only be observed with TF sensors at temperatures up to approx.
300 °C (572 °F). For this reason, thin-film sensors are generally only used for temperature
measurements in ranges below 400 °C (752 °F).

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.
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®,

Calibration
• RTD: 3G / 10 to 500 Hz according to IEC 60751
• RTD iTHERM StrongSens Pt100 (TF, vibration resistant): Up to 60G
• TC: 4G / 2 to 150 Hz according to IEC 60068-2-6
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.

Mounting location
Orientation
The installation location must meet the requirements listed in this documentation, such as ambient
temperature, protection classification, climatic class, etc.. Care should be taken when checking the
sizes of possible existing support frames or brackets welded on the wall of the storage tank or of any
other existing frame in the installation area.
The rope multipoint thermometer can be installed in vertical position. The rooftop of the storage
tank or silo can be either horizontal or oblique, the rope-joint will automatically adjust its inclination
to keep the rope always straight in vertical position.

6 Installation examples
1 TMS 31 hooked to anchored to the bottom
2 TMS 31 with free hanging weight
The rope multipoint thermometer is designed to be installed with a flanged process connection into a
storage tank, silo or similar environment. All parts and components have to be handled with care.
During the installation phase, lifting and inserting the device through the preset nozzle, the
following must be avoided:
• Misalignment with the nozzle axis.
• Any load on the welded or threaded parts due to the action of the weight of the device.
• Deformation or crushing of the threaded components, bolts, nuts, cable glands and compression
fittings.
• Friction between the temperature probes and the internals of the storage tank.
• Avoid any excessive twisting of the rope around its axis which may cause damage to the rope or to
the temperature probes.
Ensure that:
• In case of hanging weight design, the same is not touching the bottom of the storage tank.
• In case of swage eye design, the rope is correctly tensioned thanks to proper hooks or similar
systems (end users responsibility).

Process
Agriculture:
The loading and unloading forces and the connection to the tank or silo are the minimum input
parameters for the selection of the right product configuration. If special design is requested,
additional data such as type of stored material, geometry of the container and type of connection
have to be considered as mandatory for the whole product definition.
Petrolchemical, Oil & Gas:
The process temperature and process pressure are the minimum input parameters for the selection
of the right product configuration. If special product features are requested, additional data such as
process fluid type, phases, concentration, viscosity, stream and turbulences, corrosion rate have to be
considered as mandatory for the whole product definition.

Process pressure range
Design, dimensions
–10 to +100 °C (+14 to +212 °F).
Up to 40 bar (580.1 psi)
Anyhow, the maximum required process pressure has to be combined with the maximum
design process temperature. Process connections like compression fittings and flanges with
their specific ratings define the maximum operating conditions. Endress+Hauser experts can
support the customer on any related questions.
Process application examples:
• Storage of Hydrocarbons
• LPG/LNG
• Liquid Nitrogen
• Organic bulk material storage (cereals, crop, …)
• Grain silos
• Bulk liquid storage tank
• Beverage processing
Mechanical construction
The overall rope assembly is made of different parts. The rope joint ensures sufficient 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.

Materials
The weight can vary depending on the configuration: Dimension and content of the junction box,
neck length, dimensions of process connection, the number of inserts and the weight of the rope
end. The approximate weight of a typically configured multipoint rope (number of inserts = 12,
flange size = 3", medium size junction box) = 55 kg (121 lb)
It refers to insert sheath, neck extension, junction box and all wetted parts.
The temperatures for continuous operation specified in the following table are only intended as
reference values for use of the various materials in air and without any significant compressive load.
The maximum operation temperatures are reduced considerably in some cases where abnormal
conditions such as high mechanical load occur or in aggressive media.
