Measuring principle Resistance thermometer (RTD)

These resistance thermometers use a Pt100 temperature sensor according to IEC 60751. The
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-1.

iTHERM TM412

4 Endress+Hauser

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 (1 112 °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).

Output signal

Generally, the measured value can be transmitted in one of two ways:

• Directly-wired sensors - sensor measured values forwarded without a transmitter.

• Via all common protocols by selecting an appropriate Endress+Hauser iTEMP temperature
transmitter. All the transmitters listed below are mounted directly in the terminal head and wired
with the sensory mechanism.

Self heating

RTD elements are passive resistances that are measured using an external current. This
measurement current causes a self-heating effect 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 self­heating error is negligible when an Endress+Hauser iTEMP temperature transmitter (very small
measurement current) is connected.

Calibration

Calibration of thermometers

Calibration involves comparing the measured values of a device under test (DUT) with those of a
more precise calibration standard using a defined and reproducible measurement method. The aim is
to determine the deviation of the DUT's measured values from the true value of the measured
variable. Two different methods are used for thermometers:

• Calibration at fixed-point temperatures, e.g. at the freezing point of water at 0 °C,

• Calibration compared against a precise reference thermometer.
The thermometer to be calibrated must display the fixed point temperature or the temperature of

the reference thermometer as accurately as possible. Temperature-controlled calibration baths with
very homogeneous thermal values, or special calibration furnaces into which the DUT and the
reference thermometer, where necessary, can project to a sufficient degree, are typically used for
thermometer calibrations.

The measurement uncertainty can increase due to heat dissipation errors and short immersion
lengths. The existing measurement uncertainty is listed on the individual calibration certificate.

For accredited calibrations according to ISO17025, the measurement uncertainty shouldn’t be twice
as high as the accredited measurement uncertainty. If this is exceeded, only a factory calibration can
be performed.

Evaluation of thermometers

If a calibration with an acceptable uncertainty of measurement and transferable measurement
results is not possible, Endress+Hauser offers customers a thermometer evaluation measurement
service, if technically feasible. This is the case when:

• The process connections/flanges are too big or the immersion length (IL) is too short to allow the
DUT to be immersed sufficiently in the calibration bath or furnace (see the following table), or

• Due to heat conduction along the thermometer tube, the resulting sensor temperature generally
deviates significantly from the actual bath/furnace temperature.

The measured value of the DUT is determined using the maximum possible immersion depth and the
specific measuring conditions and measurement results are documented on an evaluation certificate.

Sensor transmitter matching

The resistance/temperature curve of platinum resistance thermometers is standardized but in
practice it is rarely possible to keep to the values precisely over the entire operating temperature
range. For this reason, platinum resistance sensors are divided into tolerance classes, such as Class
A, AA or B as per IEC 60751. These tolerance classes describe the maximum permissible deviation of
the specific sensor characteristic curve from the standard curve, i.e. the maximum temperature­dependent characteristic error that is permitted. The conversion of measured sensor resistance
values to temperatures in temperature transmitters or other meter electronics is often susceptible to
considerable errors as the conversion is generally based on the standard characteristic curve.

When using temperature transmitters from Endress+Hauser, this conversion error can be reduced
significantly by sensor-transmitter matching:

• Calibration at three temperatures at least and determination of the actual temperature sensor
characteristic curve,

• Adjustment of the sensor-specific polynomial function using Calendar-van Dusen (CvD)
coefficients,

• Configuration of the temperature transmitter with the sensor-specific CvD coefficients for
resistance/temperature conversion, and

• another calibration of the reconfigured temperature transmitter with connected resistance
thermometer.

Endress+Hauser offers this kind of sensor-transmitter matching as a separate service. Furthermore,
the sensor-specific polynomial coefficients of platinum resistance thermometers are always provided
on every Endress+Hauser calibration certificate where possible, e.g. at least three calibration points,
so that users themselves can also appropriately configure suitable temperature transmitters.

For the device, Endress+Hauser offers standard calibrations at a reference temperature of
–20 to +500 °C (–4 to +932 °F) based on the ITS90 (International Temperature Scale). Calibrations in
other temperature ranges are available from your Endress+Hauser sales center on request.
Calibrations are traceable to national and international standards. The calibration certificate is
referenced to the serial number of the device. Only the insert is calibrated.

Minimum insertion length (IL) for inserts required to perform a correct calibration

The insert length IL is automatically calculated for every thermometer configuration in the

software application. The system also automatically
checks whether the selected insert length suffices to perform a factory calibration. For further
information, see the 'Accessories' section →  38

iTHERM TM412

14 Endress+Hauser

Due to restrictions of the bath geometries, minimum immersion lengths must be maintained at high
temperatures in order to be able to perform a calibration with acceptable measurement uncertainty.
The same applies when a temperature head transmitter is used. Due to the heat dissipation,
minimum immersion lengths must be maintained in order to ensure the functionality of the
transmitter –40 to +85 °C (–40 to +185 °F).

ΔL Additional length, depending on the calibration unit, if the insert cannot be fully immersed

• To check the actual accuracy rating of the thermometers installed, a cyclic calibration of the
installed sensor needs to be performed frequently. The insert is normally removed for comparison
with a precise reference thermometer in the calibration bath (see graphic, left part).
A reproducible calibration requires the insert to have a minimum insertion length IL. If the insert
is shorter than this minimum length, this reproducibility cannot be guaranteed.

• The iTHERM QuickNeck enables quick, tool-free removal of the insert for calibration purposes. The
entire upper part of the thermometer is released by turning the terminal head. The insert is
removed from the protection tube and directly immersed into the calibration bath (see graphic,
right part). Make sure that the cable is long enough to be able to reach the mobile calibration bath
with the cable connected. If this is not possible for the calibration, it is advisable to use a
connector. →  28

Advantages of iTHERM QuickNeck:

• Considerable time savings when recalibrating the device (up to 20 minutes per measuring point)

• Wiring mistakes avoided when re-installing

• Minimum plant downtime, thereby saving costs

iTHERM TM412

Endress+Hauser 15

The minimum immersion length is the length of the insert that is fully immersed in the
calibration bath. For a valid recalibration, the value selected for the length IL* must be at least
the value of the previously defined minimum insertion lengths (IL) of the specific types of
insert. For more detailed values, see the previous tables, values without head transmitter.
If the calibration unit used does not allow the insert to be fully immersed as far as the bottom
edge of the top part of the iTHERM QuickNeck, it might be necessary to add an additional
length (ΔL) to IL*. →  13

Installation

Orientation

No restrictions. However, self-draining in the process must be guaranteed. If there is an opening to
detect leaks at the process connection, this opening must be at the lowest possible point.

Installation instructions

The immersion length of the thermometer can influence 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 ideally be half of the
pipe diameter.

• Installation possibilities: Pipes, tanks or other plant components

• To minimize the error caused by heat conduction, a minimum immersion length is recommended
depending on the type of sensor used and the design of the insert. This immersion depth
corresponds to the minimum insertion length for the calibration. →  13

In the case of pipes with a small nominal diameter, it is advisable for the tip of the thermometer
to project well into the process so that it extends past the pipe axis. Installation at an angle (4)
could be another solution. When determining the immersion length or installation depth all the
parameters of the thermometer and of the medium to be measured must be taken into account
(e.g. flow velocity, process pressure).

The use of iTHERM QuickSens inserts is recommended for immersion lengths U <

Due to the small immersion length U, the use of iTHERM QuickSens inserts is recommended.

Tip shape

The thermal response time, the reduction of the flow cross-section and the mechanical load that
occurs in the process are the criteria that matter when selecting the shape of the tip. Advantages of
using reduced thermometer tips:

• A smaller tip shape has less impact on the flow characteristics of the pipe carrying the medium.

• The flow characteristics are optimized, thereby increasing the stability of the protection tube.

• Endress+Hauser offers users a range of protection tube tips to meet every requirement:
– Straight tip
– Reduced tip with 4.76 mm (³⁄₁₆ in): walls of lower thickness significantly reduce the response

times of the overall measuring point
