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 200 °C (392 °F).

Measuring system
1 Application example
1 Mounted thermometer with head transmitter installed.
2 RIA15 process display - 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 process display unit is integrated in the 4 to 20 mA or HART® loop and
is powered directly from the current loop. Optionally up to four of a sensor's HART® process variables can be
displayed. More information on this can be found in the Technical Information, see "Documentation".
3 Active barrier RN221N - The RN221N (24 VDC, 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".

Output
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 or as field
transmitter and wired with the sensory mechanism.
Family of temperature transmitters
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.
PC programmable 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® programmable 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. It can be installed as an
intrinsically safe apparatus in Zone 1 hazardous areas and is used for instrumentation in the
terminal head (flat face) as per DIN EN 50446. Swift and easy operation, visualization and
maintenance using universal device configuration tools like FieldCare, DeviceCare or
FieldCommunicator 375/475. 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.

High temperature range 20 s 25 s 30 s
Low temperature range 25 s 30 s 35 s
Response times for RTD assemblies with thermowell are provided for general design guidance
without transmitter.
When the temperature of a process media changes, the output signal of a RTD assembly follows this
change after a certain time delay. The physical cause is the time related to heat transfer from the
process media through the thermowell and the insert to the sensor element (RTD). The manner in
which the reading follows the change in temperature of the assembly over time is referred to as the
response time. Variables that influence or impact the response time are:
• Wall thickness of thermowell
• Spacing between RTD insert and thermowell
• Sensor packaging
• Process parameters such as media, flow velocity, etc.

The units are factory tested with 500 VAC for one minute between live parts (terminals) and exposed
non-current-carrying metal parts (e.g. probe sheath).
Self heating
Calibration specifications
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.
The manufacturer provides comparison temperature calibrations from –20 to 300 °C (–4 to 572 °F)
on the International Temperature Scale of 1990. Calibrations are traceable to standards maintained
by the National Institute of Standards and Technology (NIST). Calibration services are in
conformance with ASTM E220, IEC 17025 and ANSI/NCSL Z540-1-1994. The report of calibration
is referenced to the serial number of the assembly.
Three point calibrations are provided, given that the specified temperatures are within the
recommended range and the minimum length requirements are met as specified. The minimum
length is based on the overall length "x" of the spring loaded insert.

the pipe (= U)
B Threaded, angled installation of T13 assembly
C Flange installation of T14 assembly
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). 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
• Minimum immersion length per ASTM E644, ΔT ≤ 0.05 °C (0.09 °F):
For temperature assemblies with themowell (T13 and T14) the minimum immersion is the depth to
which the thermowell is immersed in the medium, measured from the tip. To minimize errors from
ambient temperature the following minimum immersion lengths are recommended:
Construction Minimum immersion
Stepped thermowell 63.5 mm (2.5 in)
Tapered thermowell 114.3 mm (4.5 in)
¾" straight thermowell 101.6 mm (4 in)
