Function and system design

Measuring principle These resistance thermometers use a Pt100 temperature sensor according to IEC 60751. This temperature

sensor is a temperature-sensitive platinum resistor with a resistance of 100  at 0 °C (32 °F) and a
temperature coefficient  = 0.003851 °C

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 (1112
°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).

Example of an application

A Built-in RTD assembly TR11 with head transmitter
B RIA261 Field display

– The display measures an analog measurement signal and indicates this on the display. The display is

connected in a 4 to 20 mA current loop and also derives its supply from the loop. The voltage drop is almost
negligible (< 2.5 V). The dynamic internal resistance (load) makes sure that independently from the loop
current, the maximum voltage drop is never exceeded. The analog signal at the input is digitalized, analyzed,
and shown in the rear illuminated display. For details see Technical Information (see chapter
"Documentation").

C Active barrier RN221N

– The RN221N active barrier (24 V DC, 30 mA) has a galvanically isolated output for supplying voltage to loop

powered transmitters. The power supply has a wide-range input for mains power, 20 to 250 V DC/AC,
50/60 Hz to be used in any electrical circuit. For details see Technical Information (see chapter
"Documentation").

The Omnigrad M TR11 RTD assemblies are modular. The terminal head serves as a connection module
for the protection armature in the process as well as for the mechanical and electrical connection of the
measuring insert. The actual RTD sensor element is fitted in and mechanically protected within the
insert. The insert can be exchanged and calibrated even during the process. Either ceramic terminal
blocks or transmitters can be fitted to the internal base washer. TR11 RTD assemblies are constructed
without a neck.

The pressure values to which the actual protection tube can be subjected at the various temperatures
and maximum permitted flow velocity are illustrated by the figure below. Occasionally, the pressure
loading capacity of the process connection can be considerably lower. The maximum allowable process
pressure for a specific thermometer is derived from the lower pressure value of the thermowell and
process connection.

Insulation resistance Insulation resistance 100 M at ambient temperature.

Insulation resistance between each terminal and the sheath is measured with a voltage of 100 V DC.

Self heating RTD elements are passive resistances that are measured using an external current. This measurement

current causes a self heating 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 specifications Endress+Hauser provides comparison temperature calibration from -80 to +600 °C (-110 °F to 1112

°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.

Installation examples

A - B: In pipes with a small cross section the sensor tip should reach or extend slightly past the center line of the pipe (= L).
C - D: Tilted 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 must be half of the pipe diameter,
ideally.

• Installation possibilities: Pipes, tanks or other plant components

• 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!

When operating in small nominal bore pipes it must be guaranteed that the thermowell tip is
extending far enough into the process to reach out past the pipe center line (see Pos. A and
B). A further solution could be an angled (tilted) installation (see Pos. 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).

Certificates and approvals

CE Mark The device meets the legal requirements of the EC directives if applicable. Endress+Hauser confirms

that the device has been successfully tested by applying the CE mark.

Hazardous area approvals For further details on the available Ex versions (ATEX, CSA, FM, etc.), please contact your nearest

Endress+Hauser sales organization. All relevant data for hazardous areas can be found in separate Ex
documentation. If required, please request copies.

Other standards and guidelines

PED approval The thermometer complies with paragraph 3.3 of the Pressure Equipment Directive (97/23/CE) and

structure of the product and refers to the parts of the sensor in contact with the process fluid. Other
types of certificates related to materials 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.

standard. With regards 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 certified
for use in Ex Zones, are always tested to pressures according to the same criteria. Tests according to
other specifications can be carried out on request. Dye penetration tests verify the absence of cracks on
the thermowell welding.

Test report and calibration 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 or DKD calibration) 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.
