Function and system design
Measuring principleThermocouples 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 Temperature transmitter iTEMP
of the
thermocouple thermometer and converts them into an analog 4 to 20 mA measurement signal.
C 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").
D Active barrier RN221N
– The RN221N active barrier (24 V DC, 30 mA) has an 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").

6 Metal or ceramic protection tube for TAF16
TAF series high temperature assemblies are manufactured according to international DIN EN 50446
standards. These products consist of a measuring insert, a protection tube, a metal sleeve (only TAF11/
TAF12x) and a terminal head, which contains a transmitter or terminal block as electrical connection.
Measuring insert
The measuring point of the thermocouple is located close to the tip of the insert. The operating
temperature ranges (→ ä 4) and permissible deviation limits of the thermoelectric voltages from the
standard characteristic (→ ä 5) vary according to the type of thermocouple used. The thermocouple
wires are inserted in appropriate high-temperature-resistant ceramic isolators or in a mineral
insulated insert.
Protection tube
Two types are commonly used in this type of assembly:
• Metallic protection tube, usually machined from tubes or bars.
• Ceramic protection tube.
The selection of the protection tube materials majorly depends on the following material properties,
which will directly influence the lifetime of the sensor:
•Hardness
• Chemical resistance
• Maximum operating temperature
• Wear/abrasion resistance
•Brittleness
• Porosity for process gases
• Creep resistance
Ceramic materials are commonly used for highest temperatures and, due to their hardness, for
applications with high abrasion rates. Attention has to be paid regarding the brittleness of these
materials when exposed to high mechanical loads inside the process. When using porous ceramics as
Endress+Hauser3
TAF11, TAF12x, TAF16
external protection sheath, an additional, non-porous inner protection sheath has to be used in order
to protect the noble sensor elements from contamination leading to temperature drift.
Metal alloys generally show higher mechanical resistance but lower maximum temperature limits and
less abrasion resistance. All metal alloys are non-porous and usually there is no need for an additional
inner protection sheath.
Metal sleeve and process connection
The TAF11 and TAF12 ceramic protection tubes are mounted into a metal sleeve which connects them
towards the terminal head. Also the process connection is fitted on the metal sleeve due to its higher
mechanical strength. The dimensions and material type for the sleeve are related to the process
temperatures and insertion length of the ceramic protection tubes.
All high temperature assemblies are available with an adjustable flange, stop flanges or gas tight
compression fittings.

Calibration specificationsEndress+Hauser provides comparison temperature calibration from -80 to +1400 °C (-110 °F to 2552
°F) based on the International Temperature Scale (ITS90). Calibrations are traceable to national and
international standards. The calibration report is referenced to the serial number of the thermometer.
Only the measurement insert is calibrated. In the case of thermometers without a replaceable insert,
the entire thermometer - from the process connection to the tip of the thermometer - is calibrated.

depends on the protection tube material used. Dimensions in mm (in).
When configuring the high temperature assemblies of the TAF family the thermocouple wire
diameter also needs to be defined. The higher the temperature the larger the wire diameter
needs to be selected. A large wire diameter will increase the lifetime of the sensor. The insert
diameter depends on the inner diameter of the protection tube. If possible, the insert with the
greater diameter will be installed. This leads to a stable measurement of high temperatures.

Installation conditions
OrientationVertical and horizontal installation. A vertical installation should be preferred due to possible
irreversible bending of metal tubes and the brittleness of the ceramic materials, which could be hit by
falling parts.

Immersion length
Recommended maximum immersion length Lg for horizontal mounting:
• 1500 mm (59 in) for diameter > 20 mm (0.8 in)
• 1200 mm (47.3 in) for diameter < 20 mm (0.8 in)
When installing longer lengths than the recommended maximum in horizontal position, the
protection tube might be bend irreversibly under its own weight in the hot environment.
Installation of ceramic sheaths
Gas tight ceramic protection tubes and inserts are sensitive to fast temperature changes: In order to
reduce the risk of thermal shock and prevent the sheaths from failure, gas tight ceramic sheaths must
be heated before installation. Two possibilities are applicable:
• Installation with pre-heating
At process temperatures ≥ 1000 °C (1832 °F) the ceramic part of the protection tube must be preheated from room temperature to 400 °C (752 °F). It is suggested to use a horizontal, cylindrical
cross-section oven or cover the ceramic part with electric heating elements. Do not use direct flames.
It is suggested to pre-heat the ceramic sheath in situ and then proceed immediately with the
insertion. The protection tube and inserts shall be installed carefully with an insertion rate of 100
mm/min, avoiding any mechanical shock. If it is not possible to run the pre-heating phase near the
plant, the insertion rate must be lowered to 30 mm/min because of the cooling of the system during
the transportation.
• Installation without pre-heating
The insert shall be installed at process working temperature inserting the ceramic sheath in the
plant for a length equal to the wall thickness, including the insulation material, and left in that
position for 2 hours.
After this time, the device shall be installed at a rate of 30 mm/min avoiding any mechanical shock.

Sleeve lengthThe sleeve is the part between the process connection and the terminal head.
As illustrated in the following figure, the sleeve length may influence the temperature in the terminal
head. It is necessary that this temperature is kept within the limit values defined in the chapter
"Operating conditions".
