Output
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 or as field
transmitter and wired with the sensory mechanism.
Thermometers fitted with iTEMP transmitters are an installation-ready complete solution to
improve temperature measurement by significantly increasing accuracy and reliability, when
compared to direct wired sensors, as well as reducing both wiring and maintenance costs.
PC programmable head transmitters
They offer a high degree of flexibility, thereby supporting universal application with low inventory
storage. The iTEMP transmitters can be configured quickly and easily at a PC. Endress+Hauser offers
free configuration software which can be downloaded from the Endress+Hauser Website. More
information can be found in the Technical Information. → 38
HART® programmable head transmitters
The transmitter is a 2-wire device with one or two measuring inputs and one analog output. The
device not only transfers converted signals from resistance thermometers and thermocouples, it also
transfers resistance and voltage signals using HART® communication. It can be installed as an
intrinsically safe apparatus in Zone 1 hazardous areas and is used for instrumentation in the
terminal head (flat face) as per DIN EN 50446. Swift and easy operation, visualization and
maintenance by using universal device configuration tools like FieldCare, DeviceCare or
FieldCommunicator 375/475. For more information, see the Technical Information. → 38
PROFIBUS® PA head transmitters
Universally programmable head transmitter with PROFIBUS® PA communication. Conversion of
various input signals into digital output signals. High accuracy over the complete ambient
temperature range. The configuration of PROFIBUS PA functions and of device-specific parameters is
performed via fieldbus communication. For more information, see the Technical Information.
→ 38
FOUNDATION Fieldbus™ head transmitters
Universally programmable head transmitter with FOUNDATION Fieldbus™ communication.
Conversion of various input signals into digital output signals. High accuracy over the complete
ambient temperature range. All transmitters are released for use in all important process control
systems. The integration tests are performed in Endress+Hauser's "System World". For more
information, see the Technical Information. → 38
Advantages of the iTEMP transmitters:
• Dual or single sensor input (optionally for certain transmitters)
• Unsurpassed reliability, accuracy and long-term stability in critical processes
• Mathematical functions
• Monitoring of the thermometer drift, sensor backup functionality, sensor diagnostic functions
• Sensor-transmitter matching for dual sensor input transmitter, based on Callendar/Van Dusen
coefficients

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
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,

IL Insertion length for factory calibration or recalibration onsite without the iTHERM QuickNeck extension neck
IL* Insertion length for recalibration onsite with the iTHERM QuickNeck extension neck
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
14 Endress+Hauser

iTHERM TM412
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

Insulation resistance
Orientation
Installation instructions
Insulation resistance ≥ 100 MΩ at ambient temperature.
Insulation resistance between the terminals and the outer jacket is measured with a minimum
voltage of 100 V DC.
Installation
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.
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
• ATEX certification: Observe the installation instructions in the Ex documentation! → 38

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 <
70 mm (2.75 in).

Procedure in case of seal failure:
• Disassembling of the thermometer, validated cleaning procedure of thread and sealing ring
groove
• Replacement of the seal or sealing ring
• CIP after re-assembly
In the case of weld-in connections, exercise the necessary degree of care when performing the
welding work on the process side:
• Suitable welding material
• Flush-welded or with welding radius > 3.2 mm (0.13 in)
• No recesses, folds or gaps
• Honed and polished surface, Ra ≤ 0.76 µm (30 µin)
As a general rule, the thermometers should be installed in such a way that does not impact
their ability to be cleaned (the requirements of the 3-A Sanitary Standard must be observed).
The Varivent® and Liquiphant-M weld-in adapter enable flush-mounted installation.

The highest flow velocity tolerated by the thermometer diminishes with increasing insert 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

The iTHERM TS212 insert is available as a spare part. The insert length (IL) depends on the
immersion length of the protection tube (U), the length of the extension neck (E) and the length of
the protection tube shaft (T). The insertion length (IL) must be taken into consideration when
replacing the unit.
This can be calculated by means of the following formula: IL = U + T + E + 38.1 mm (1.5 in)

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
