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 Thermometer with fitted head transmitter mounted in an existing onsite thermowell
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").

34Terminal head

Thermowell connection: Threaded connection or
compression fitting on extension neck

The resistance thermometers from the Omnigrad S TR88 series have a modular design. The terminal head is
used as a connection module for the mechanical and electrical connection of the insert. The actual sensor
element of the resistance thermometer sits in the insert and is mechanically protected. If installed in a
thermowell, the insert can be replaced and calibrated directly in the process. Either ceramic connection sockets
or transmitters can be mounted on the internal connection socket.
The TR88 is designed for installation in an existing onsite thermowell. Different threaded connections are
available on the bottom of the extension neck for installation in the thermowell. Insofar as the thermowell is
suited to this purpose, the thermometer may also be mounted using a suitable compression fitting on the
extension neck. This means that thermometers with a fixed insertion length can be used variably, even in
thermowells of varying length, and can be installed in such a way that an optimum thermal contact is
guaranteed between the tip of the insert and the bottom of the thermowell.

Permitted flow rate as a function of immersion length

The maximum permitted flow rate to which the thermometer can be subjected, reduces the greater the
immersion depth of the thermowell in the flowing medium. In addition, it is dependent on the diameter of the
tip of the thermowell, the medium type, process temperature and process pressure. For an overview of the
Endress+Hauser thermowells which may be used, see → ä 17.

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.

iTEMP

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.

Properties

• Austenitic, stainless steel

• High corrosion resistance in general

• Particularly high corrosion resistance in chlorine-based and acidic, non-oxidizing atmospheres
through the addition of molybdenum (e.g. phosphoric and sulfuric acids, acetic and tartaric
acids with a low concentration)

• Increased resistance to intergranular corrosion and pitting

• Compared to 1.4404, 1.4435 has even higher corrosion resistance and a lower delta ferrite
content

• Properties comparable to AISI316L

• Addition of titanium means increased resistance to intergranular corrosion even after welding

• Broad range of uses in the chemical, petrochemical and oil industries as well as in coal
chemistry

• Can only be polished to a limited extent, titanium streaks can form

1) Can be used to a limited extent up to 800 °C (1472 °F) for low compressive loads and in non-corrosive media. Please contact your Endress+Hauser sales team

Installation instructions

The thermometer is designed for installation in an
existing thermowell or in a thermowell which can be
ordered separately. Different threaded connections to
suit the thermowell are available on the
thermometer's extension neck (→ ä 11).
The necessary insertion length (ML) of the insert
depends on the total length of the thermowell (A) and
the type of thermowell used. It can be freely selected
within the range of 100 to 5000 mm (3.94 and 197
in). Longer insertion lengths are available on request.
The same also applies when ordering an insert as a
spare part. More detailed information on determining
the insertion length (ML) required in each case can be
found in the following table (applies to
Endress+Hauser thermowells with standard base
thicknesses).
