Function and system design

Measuring principle 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).

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.

A Mounted thermometer with head transmitter installed.
B RIA16 field display unit - The display unit records the analog measuring signal from the head transmitter and

shows this on the display. The LC display shows the current measured value in digital form and as a bar graph
indicating a limit value violation. The display unit is looped into the 4 to 20 mA circuit and gets the required
energy from there. More information on this can be found in the Technical Information (see "Documentation").

C Active barrier RN221N - The RN221N (24 V DC, 30 mA) active barrier 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.
More information on this can be found in the Technical Information (see "Documentation").

Endress+Hauser 3

Thermometers from the Omnigrad M TR13 and TC13 series have a modular design. The terminal
head is used as a connection module for the mechanical and electrical connection of the insert. The
position of the actual thermometer sensor in the insert ensures that it is mechanically protected. The
insert can be exchanged and calibrated without interrupting the process. Either ceramic terminal
blocks or transmitters can be fitted to the internal base washer.

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 terminal head 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.

4 to 20 mA 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® 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. Swift and easy operation,
visualization and maintenance using universal device configuration tools like FieldCare, DeviceCare
or FieldCommunicator 375/475. Integrated Bluetooth® interface for the wireless display of
measured values and configuration via E+H SmartBlue (app), optional. 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. The configuration of PROFIBUS PA functions and of device-specific parameters is
performed via fieldbus communication. 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. All transmitters are released for use in all important process control
systems. The integration tests are performed in Endress+Hauser's "System World". For more
information, see the Technical Information.

Advantages of the iTEMP transmitters:

• Dual or single sensor input (optionally for certain transmitters)

• Pluggable display (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 transmitters, based on Callendar/Van Dusen
coefficients

RTD elements are passive resistances that are measured using an external current. This
measurement current causes a self-heating effect in the RTD element itself which in turn creates an
additional measurement error. In addition to the measurement current, the size of the measurement
error is also affected by the temperature conductivity and flow velocity of the process. This self­heating error is negligible when an Endress+Hauser iTEMP temperature transmitter (very small
measurement current) is connected.

Endress+Hauser provides comparison temperature calibration from
–80 to +1 400 °C (–110 to +2 552 °F) based on the International Temperature Scale (ITS90).

Process connection

The following figure shows the basic dimensions of the available flanges.

Flange

For detailed information on the flange
dimensions refer to the following flange
standards:

• ANSI/ASME B16.5

• ISO 7005-1

 7 Installation examples

A-B In pipes with a small cross section the thermowell tip should reach or extend slightly past the center line of

the pipe (=L).

C-D Angled installation.

The immersion length of the thermometer influences the accuracy. If the immersion length is too
small then errors in the measurement are caused by heat conduction via the process connection and
the container wall. If installing into a pipe then the immersion length should be at least half of the
pipe diameter. A further solution could be an angled (tilted) installation (see C and D). When
determining the immersion length all thermometer parameters and the process to be measured
must be taken into account (e.g. flow velocity, process pressure).

• Installation possibilities: Pipes, tanks or other plant components

• Recommended minimum immersion length: 80 to 100 mm (3.15 to 3.94 in)
The immersion length should correspond to at least 8 times of the thermowell diameter. Example:
Thermowell diameter 12 mm (0.47 in) x 8 = 96 mm (3.8 in). A standard immersion length of
120 mm (4.72 in) is recommended.

• ATEX certification: Always take note of the installation regulations!

The material certificate 3.1 (according to standard EN 10204) can be requested separately. The
"short form" certificate includes a simplified declaration with no enclosures of documents related to
the materials used in the construction of the single sensor and guarantees the traceability of the
materials through the identification number of the thermometer. The data related to the origin of
the materials can subsequently be requested by the client if necessary.

Thermowell pressure tests are carried out in accordance with the specifications in DIN 43772. With
regard to thermowells with tapered or reduced tips that do not comply with this standard, these are
tested using the pressure of corresponding straight thermowells. Sensors for use in hazardous areas
are also always subjected to a comparative pressure during the tests. Tests according to other
specifications can be carried out on request. The liquid penetration test verifies that there are no
cracks in the welded seams of the thermowell.

The "Factory calibration" is carried out according to an internal procedure in a laboratory of Endress
+Hauser accredited by the European Accreditation Organization (EA) to ISO/IEC 17025. A

calibration which is performed according to EA guidelines (SIT/Accredia) or (DKD/DAkkS) may be
requested separately. The calibration is performed on the replaceable insert of the thermometer. In
the case of thermometers without a replaceable insert, the entire thermometer - from the process
connection to the tip of the thermometer - is calibrated.
