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).
For this reason, thin-film sensors are generally only used for temperature measurements in ranges
below 400 °C (932 °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.

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.

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.

Self heating 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 self-
heating error is negligible when an Endress+Hauser iTEMP® temperature transmitter (very small
measurement current) is connected.
Calibration Endress+Hauser provides comparison temperature calibration from
–80 to +1 400 °C (–110 to +2 552 °F) based on the International Temperature Scale (ITS90).

Jacket
For thermowells with straight tip shape and protection tube diameter 11 mm (PTFE/Tantalum) and
12 mm (PVDF) (0.43 and 0.47 in), a jacket in PTFE (Teflon®), PVDF or Tantalum is available. The
external diameter of the thermowell stem will be 15 mm (PTFE) and 16 mm (PVDF) (0.6 and 0.63
in), for Tantalum 12 mm (0.47 in). The immersion length L will be slightly higher also because of
the different thermal expansion of the thermowell and jacket. The upper part of the jacket is fitted
with a disc of the same material that is inserted between the flange and counterflange.

For detailed information on the flange
dimensions refer to the following flange
standards:
•ANSI/ASME B16.5
• ISO 7005-1
• EN 1092-1
• JIS B 2220 : 2004
The flange material must be the same as of the stem of the
thermowell. For this reason, connections are available both
in 316L/1.4404 and in 316Ti/1.4571. Models in Hastelloy®
have flanges in basic material 316L/1.4404 and a disc in
Hastelloy® on the surface in contact with the process media.
For the specification PVDF/PTFE/Tantalum thermowell an
additional jacket with a disc on the upper end will be used.
The standard surface finish of the coupling side of flanges
ranges from 3.2 to 6.4 µm (Ra). Other types of flanges can
be supplied on request.

 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!
