Measuring principle

Resistance thermometers (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.
There are generally two different kinds of platinum resistance thermometers:• Wire-wound (WW):Wire Wound, WW In these thermometers, a double coil of fine, high-purity
platinum wire is accommodated in a ceramic support. This support 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 andis comparatively sensitive to vibrations.
• Thin-film platinum resistance thermometers(Thin Film, 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 measuringresistance. 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 class A as per
IEC 60751 can only be observed with TF sensors at temperatures up to approx. 300 °C (572 °F).
Thermocouples (TC)
Thermocouples are comparatively simple, robust temperature sensors which use the Seebeck effectfor temperature measurement: if two electrical conductors made of different materials are connected
at a point, a weak electrical voltage can be measured between the two open conductor ends if the
conductors are subjected to a thermal gradient. This voltage is called thermoelectric voltage orelectromotive force (emf). Its magnitude depends on the type of conducting materials and thetemperature difference between the "measuring point" (the junction of the two conductors) and the"cold junction" (the open conductor ends). Accordingly, thermocouples primarily only measuredifferences in temperature. The absolute temperature at the measuring point can be determinedfrom these if the associated temperature at the cold junction is known or is measured separately andcompensated for. The material combinations and associated thermoelectric voltage/temperature
characteristics of the most common types of thermocouple are standardized in the IEC 60584 and
ASTM E230/ANSI MC96.1 standards.

Measuring system

Endress+Hauser offers a complete portfolio of optimized components for the temperature measuring
point – everything you need for the seamless integration of the measuring point into the overall
facility. These include:• Power supply unit/barrier• Display units• Surge arrester

Example of application, measuring point layout with additional Endress+Hauser components
Installed iTHERM thermometer with HART® communication protocol
RIA15 loop-powered process indicator - The process indicator is incorporated into the current loop anddisplays the measuring signal or the HART® process variables in digital form. The process display unit does
not require an external power supply. It is powered directly from the current loop.
Active barrier RN42 - The RN42 (17.5 VDC, 20 mA) active barrier has a galvanically isolated output for
supplying voltage to loop-powered transmitters. The universal power supply works with an input supply
voltage of 24 to 230 V AC/DC, 0/50/60 Hz, which means that it can be used in all international power grids.
Communication examples: HART® Communicator (handheld terminal), FieldXpert, Commubox FXA195 for
intrinsically safe HART® communication with FieldCare via the USB interface, Bluetooth® technology with
SmartBlue App.
FieldCare is a FDT-based plant asset management tool from Endress+Hauser, for details see section"accessories".

Terminals

iTEMP head transmitters fitted with push-in terminals unless screw terminals are explicitly selected,
the second process seal is chosen or a double sensor is installed.

Cable entries

See "Terminal heads" section.
The cable entries must be selected during the configuration of the device. Different terminal heads
offer different possibilities with regard to threads and the number of available cable entries.
Connectors
Endress+Hauser offers a wide variety of connectors for the simple and fast integration of thethermometer into a process control system. The following tables show the PIN assignments of thevarious plug connector combinations.
We do not recommend connecting thermocouples directly to connectors. The direct connection
to the pins of the plug might generate a new 'thermocouple' which influences the accuracy ofthe measurement. Therefore we do not connect thermocouples directly to connectors. The
thermocouples are connected in combination with a transmitter.

Self-heating

RTD elements are passive resistors 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 isalso affected by the temperature conductivity and flow velocity of the process. This self-heating error
is negligible when an Endress+Hauser iTEMP transmitter (very small measurement current) isconnected.

Calibration of thermometers
Calibration involves comparing the measured values of a unit under test (UUT) with those of a more
precise calibration standard using a defined and reproducible measurement method. The aim is todetermine the deviation of the UUT'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 withvery homogeneous thermal values, or special calibration furnaces are typically used for thermometer
calibrations. The measurement uncertainty may increase due to heat conduction errors and shortimmersion lengths. The existing measurement uncertainty is recorded on the individual calibration
certificate. For accredited calibrations in accordance with ISO17025, a measurement uncertainty thatis twice as high as the accredited measurement uncertainty is not permitted. If this limit is exceeded,
only a factory calibration is possible.
Evaluation of thermometers
If a calibration with an acceptable measurement uncertainty 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
UUT 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 UUT is determined using the maximum possible immersion depth and thespecific 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 inpractice 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 resistancevalues to temperatures in temperature transmitters or other meter electronics is often susceptible toconsiderable errors as the conversion is generally based on the standard characteristic curve.

18

Endress+Hauser

iTHERM ModuLine TM111

When Endress +Hauser temperature transmitters are used, 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 forresistance/temperature conversion, and• another calibration of the reconfigured temperature transmitter with connected resistancethermometer.
Endress+Hauser offers its customers this kind of sensor-transmitter matching as a separate service.
Furthermore, the sensor-specific polynomial coefficients of platinum resistance thermometers arealways provided on every Endress+Hauser calibration certificate where possible, e.g. at least threecalibration points, so that users themselves can also appropriately configure suitable temperaturetransmitters.
For the device, Endress+Hauser offers standard calibrations at a reference temperature of–80 to +600 °C (–112 to +1 112 °F) based on the ITS90 (International Temperature Scale).
Calibrations in other temperature ranges are available from your Endress+Hauser sales center onrequest. 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 immersion length (IL) for inserts required to perform a correct calibration
Due to the limitations of furnace geometries, the minimum insertion lengths must be observed
at high temperatures to enable a calibration to be performed with an acceptable degree ofmeasurement uncertainty. The same applies when using a head transmitter. Due to heat
conduction, minimum lengths must be observed in order to guarantee the functionality of thetransmitter –40 to +85 °C (–40 to +185 °F)

Installation examples

1 - 2 In pipes with a small cross-section, the sensor tip should reach or extend slightly past the center axis of thepipe (=U).
3 - 4 Slanted orientation.

The immersion length of the thermometer influences the measurement accuracy. If the immersion
length is too small, errors in the measurement are caused by heat conduction via the processconnection and the container wall. Therefore, if installing in a pipe the immersion length should be
at least half the pipe diameter. Installation at an angle (see item 3 and 4) could be another solution.
When determining the immersion length, all the parameters of the thermometer and of the process
to be measured must be taken into account (e.g. flow velocity, process pressure).
The counterparts for process connections and seals are not supplied with the thermometer and must
be ordered separately if needed.

Heating of the terminal head as a function of the process temperature. Temperature in terminal head =ambient temperature 20 °C (68 °F)+ ΔT

The diagram can be used to calculate the transmitter temperature.
Example: At a process temperature of 220 °C (428 °F) and with a lagging length of
100 mm (3.94 in), the heat conduction is 40 K (72 °F). The transmitter temperature is therefore
40 K (72 °F) plus the ambient temperature, e.g. 25 °C (77 °F): 40 K (72 °F) + 25 °C (77 °F) =65 °C (149 °F).
Result: The temperature of the transmitter is OK; the length of the lagging is sufficient.
Weight

0.5 to 2.5 kg (1 to 5.5 lbs) for standard options.

Materials

The temperatures for continuous operation specified in the following table are only intended as
reference values for use of the various materials in air and without any significant compressive load.
The maximum operating temperatures can be reduced considerably in cases where abnormal
conditions such as high mechanical load occur or in aggressive media.
Please note that the maximum temperature always also depends on the temperature sensor
used.

For selection without thermowell. Only available for installation in an existing thermowell. Special attention has to be paid to the length as theinsert is not springload!

The 316L compression fittings can only be used once due to deformation. This applies to all thecomponents of the compression fittings! A replacement compression fitting must be secured atanother point (grooves in thermowell). PEEK compression fittings must never be used at atemperature that is lower than the temperature present when the compression fitting issecured. This is because the fitting would no longer be leak-tight as a result of heat contractionof the PEEK material.
SWAGELOCK or similar fittings are strongly recommended for higher requirements.

Test on thermowell

Thermowell pressure tests are carried out in accordance with the specifications in DIN 43772. With
regard to thermowells with tapered or reduced tips that do not comply with this standard, these aretested using the pressure of corresponding straight thermowells. Sensors for use in hazardous areas
are also always subjected to a comparative pressure during the tests. Tests according to otherspecifications can be carried out on request. The liquid penetration test verifies that there are no
cracks in the welded seams of the thermowell.
