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 Thermometer with fitted head transmitter
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 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").

The Omnigrad M TR10 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. Where required, threads or
compression fittings can be fixed onto the protection armature.

Permitted flow velocity depending on the immersion length

The highest flow velocity tolerated by the thermometer diminishes with increasing immersion length
exposed to the stream of the fluid. In addition it is dependent on the diameter of the thermometer tip,
on the kind of measuring medium, on the process temperature and on the process pressure. The
following figures exemplify the maximum permitted flow velocities in water and superheated steam at
a process pressure of 5 MPa (50 bar).

Response time for the sensor assembly without transmitter.

Insulation resistance Insulation resistance 100  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 instructions

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 should be half of the pipe diameter,
if possible (see A and B). 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... 100 mm (3.15... 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!

Neck tube length The neck tube is the part between the process connection and the housing.

As illustrated in the following figure, the neck tube 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".

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

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.

Test on thermowell Thermowell pressure tests are carried out in accordance with the specifications in the DIN 43772

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.
