RTD TH11 and TH12

General purpose RTD with terminal head or conductor extension
lead wires for process and laboratory applications

Areas of application

The TH11 and TH12 temperature sensors are RTD's
designed for use in the process industry or factory
automation type of environment. They are made up
of a measurement probe with a RTD, insulation and
sheath.
Among other applications the sensors can be used on:

• Heat exchangers

• Power & recovery area

• Carbon regeneration furnace

•Dryers

• Flue Gas

• Compressor stations

• Process reactors

Head Transmitters

Instead of directly wiring your temperature sensors to
your control system, use transmitters to reduce
wiring and maintenance costs while increasing
measurement accuracy.

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 is 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).

A0016255-EN

RIA16 Field indicator

The field indicator records an analog measuring signal and shows this on the display. The LCD display shows
the currently measured value digitally and as a bargraph with limit value violation signalling. The indicator is
looped into the 4 to 20 mA circuit and obtains the required energy from there. Details see Technical
Information (see "Documentation").

RNS221

The RNS221S power supply (24 V DC, 30 mA) has two galvanically isolated outputs for supplying voltage to
loop powered transmitters. The two channel power supply has a wide-range input for mains power, 20 to
253 V DC/AC, 50/60 Hz to be used in any electrical circuit. Details see Technical Information (see
"Documentation"). RNS221 is an UL recognized component to UL-3III-1.

Equipment architecture The single element RTDs are designed to measure temperature in a variety of process and laboratory

applications. These RTDs are specifically designed for use in two different process temperature ranges and they
will provide accurate and repeatable temperature measurement through a broad range of -200 to 600 °C
(-328 to 1112 °F). Low range thin film RTDs -50 to 200 °C (-58 to 392 °F) are constructed using silver plated
copper internal leads, PTFE wire insulations with potting compounds to resist moisture penetration. High range
RTDs -200 to 600 °C (-328 to 1112 °F) are constructed with nickel internal leads inside swaged MgO insulated
cable to allow higher temperature measurements at the RTD element and to provide higher temperature lead
protection along the sheath.

Self heating RTD elements are not self-powered and require a small current be passed through the device to provide a

voltage that can be measured. Self-heating is the rise of temperature within the element itself, caused by the
current flowing through the element. This self-heating appears as a measurement error and is affected by the
thermal conductivity and velocity of the process being measured; it is negligible when an Endress+Hauser

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.

A0009538

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).

For high temperature range construction with compacted magnesium oxide (MgO) the values might
be higher. In any case for different length, other materials, variation in sheath diameter or wall
