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 Ω at 0 °C (32 °F) and a temperature
coefficient α = 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 RIA 261 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 volt drop is almost negligible
(< 2.5 V). The dynamic internal resistance (load) makes sure that independently from the loop current, the
maximum volt drop is never exceeded. The analog signal at the input is digitalized, analyzed and displayed. For
details see Technical Information (see "Documentation").
B 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 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 "Documentation").

4Extension neck
The Omnigrad S TR66 RTD assemblies are modular. The terminal head serves as a connection module for the
extension neck to the thermowell 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 flanges can be fixed onto the thermowell.

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 4 MPa
(40 bar = 580 PSI).

Insulation resistance Insulation resistance ≥100 MΩ 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
®
temperature transmitter (very small measurement current) is connected.

The thermowell is the component of the RTD assembly that must tolerate most of the mechanical stress
transmitted by the process. It is made from a round bar and supplied in different materials and dimensions,
according to the chemical/physical characteristics of the process: corrosion, temperature, pressure and speed
of the fluid.
The thermowell consists of three parts:
• The lag, usually with a cylindrical shape and standard diameters of 30 or 35 mm (1.18 or 1.38 in) and lengths
of 70/100 mm (2.76/3.94 in), represents the external part of the thermowell and is connected with the
terminal head by means of a neck (usually a nipple, type N or nipple-union-nipple, type NUN).
• The immersed part (identified as U), with a conical or cylindrical shape is situated next to the process
connection in direct contact with the process fluid. The standard diameter of the area below the fitting is 20
or 25 mm (0.79 or 0.98 in).
• The threaded or flanged process connection is the part inserted between the lag and the immersed part and
guarantees the mechanical and hydraulic sealing of the assembly and plant.
The surface of the wetted part of the thermowell is available with a surface roughness rating of Ra = 1.6 μm as
standard (other surface versions available on request).

Spare parts Measuring probe (Pt100):
• TPR100 for general purpose and intrinsically safe model
• TPR300 for explosion-proof model
Both of the probes are made in mineral insulated cable (MgO), with a sheath in 316L/1.4401 stainless steel.
The insertion length (IL) of the insert can be chosen within a standard range from 50 to 1000 mm (1.97 to
39.4 in), see "Caution" on Page 9. Inserts with a insertion length IL > 1000 mm (39.4 in) can be supplied after
a technical verification of the specific application by a Endress+Hauser service organization.
When replacing the insert it is necessary to refer to the following table to obtain the correct insertion length IL
(applicable only to thermowells with standard bottom thickness). It is calculated by adding the total thermowell
length (immersion lenght U + lag T) to the extension neck length (N) used.

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
(= U).
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 must be at least half of the pipe diameter.
For best installation follow the rule: h ~ d; U > D/2 + h. As far as corrosion is concerned, the base material for
parts in contact with the fluid is able to withstand the most common corrosive agents up to the highest
temperatures. For further information on specific applications, contact a Endress+Hauser service organization.
Note!
When operating in small nominal bore pipes it must be guaranteed that the thermowell tip is long enough to
go over the pipe centre line (see figure above, A and B). A further solution could be an angled (tilted) installation
(see figure above, 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 → ä 4).
The counterparts for process connections and gaskets, when required, are not supplied with the sensor and
must be purchased separately.

Extension neck length The extension neck is the part between the thermowell connection and the terminal head. The connection
situated in the upper part of the neck allows for orientation of the terminal head. The neck is constituted by a
tube assembled to hydraulic hardware (nipples or joints) that is suitable to allow the adjustment of the sensor
to the thermowell. In addition to the standard versions listed below, it is also possible to order the extension
neck by specifying the desired length (see “Product structure” at the end of this document):

As illustrated in the following figure, the extension neck length may influence the temperature in the terminal

Test report and calibration For the tests and calibration, the "Acceptance report" comprises a declaration of conformity with the primary
points as per IEC 60751.
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.
