Function and system design
Measuring principle In the Platinum RTD (Resistance Temperature Detector) thermometers the sensing element consists of an elec-
trical resistance with value of 100Ωat 0°C (called Pt100, in compliance with standard DIN EN 60751), which
increases at higher temperatures according to a coefficient characteristic of the resistor material (platinum). In
industrial thermometers that comply with the DIN EN 60751 standard, the value of this coefficient is α=
3.85*10-3 °C-1, calculated between 0 and 100°C.
Equipment architecture The Omnigrad M TR 44 and TR 45 temperature sensors are made up of a measurement probe, with (TR 45)
or without (TR 44) a protection well, and a housing (head), which may contain a transmitter or the terminals
for the electrical connection.
In TR 45 the probe is a sensing insert, placed inside the thermowell and spring loaded underneath it, so as to
improve the heat transfer.
As in TR 44, the sensing element (Pt100) is positioned close to the tip of the probe.
The (TR 45) thermowell is obtained from a 9 mm
diameter pipe. The final (sensing) part can be
straight, tapered, i.e. with its diameter smoothly
decreased by means of a swaging procedure, or
reduced (stepped).
In the TR 44, the sheath of the probe is developed
from a 8 mm or a 6 mm pipe. In the 8 mm, the final
(sensing) part always has a reduced (stepped) diam-
eter.Inthe 6 mm, theprobepipeis always straight.
The probe (TR 44) or thermowell (TR 45) can be
installed on the plant (pipe or vessel) by means of a
hygienic process connection, which can be chosen
among the most common types (see "System com-
ponents" section).
Both TR 44 and TR 45 with Varivent®process con-
nections, are built to 3-A®and EHEDG design cri-
teria, which allow the sensor to withstand any
stress caused by CIP (Cleaning In Place) and SIP
(Sterilization In Place) processes.
The electrical structure of the instruments always
complies with DIN EN 60751 standard rules.
The housing can be of different types and materials
(plastic, painted aluminium, stainless steel).
The way in which itfits to the rest of the probe and
the gland for the cable entry ensures a minimum
grade of IP65 (Ingress Protection).

Electronics
The required type of output signal can be obtained by choosing the right head-mounted transmitter.
Endress + Hauser supplies state-of-the-art transmitters (iTEMP®series) built in 2-wire technology and with
4…20 mA, HART®or PROFIBUS-PA®output signal. All the transmitters are easily programmable with a per-
sonal computer through the ReadWin®2000 public domain software (for 4…20 mA and HART®transmitters)
or CommuWin II software (for PROFIBUS-PA®transmitters).
HART®transmitters can be programmed also with the DXR275 (Universal HART®Communicator) hand-held
operating module.
A PCP (4…20 mA) model (TMT 180) with enhanced accuracy is available and is particularly suita-
ble for hygienic applications.
E+H recommends the use of PROFIBUS dedicated connectors in the case of PROFIBUS-PA®transmitters. The
Weidmüller type (Pg 13.5 - M12) is provided as standard option.
For detailed information regarding transmitters, please refer to the relevant documentation (see TI codes at the
end of this document).
If a head-mounted transmitter is not employed, the sensor probe can be connected through the terminal block
to a remote converter (i.e. DIN rail transmitter).
Performance
Operating conditions Ambient temperature (housing without head-mounted transmitter):
• metal housings -40÷130°C
• plastic housings -40÷85°C
Ambient temperature (housing with head-mounted transmitter) -40÷85°C
Ambient temperature (housing with display) -20÷70°C
Process temperature
The measurement range (seebelow) can be limited due to the the gasket employed in the process connection.
Maximum process pressure:
• TR 44, TR 45 5 MPa (50 bar) at 20°C
• TR 44, TR 45 3.3 MPa (33 bar) at 250°C
• TR 45 2.4 MPa (24 bar) at 400°C
Lower maximum pressures can be due to the process connection (i.e. clamp, …).
Maximum flow velocity
The highest flow velocity tolerated by the sensor stem diminishes with increasing lengths of the well/probe
exposed to the stream of fluid.

Installation
Omnigrad M TR 44 and TR 45 can be mounted on
the wall of pipes or vessels.
The counterparts for the process connections and
the respective gaskets or sealing rings, are generally
not supplied with the sensors, and are considered
to be the customer's responsibility (EHEDG and 3-
A®requirements must be fulfilled).
TheG1"connectionistheonlyexception for which
the sensor with the adaptor to be welded on the
plant can be supplied.
As a general rule, the sensors should be installed in
such a way that does not adversely affect their
cleanability.
With regard to ATEX-certified components (trans-
mitter, insert), please refer tothe specific documen-
tation (see the code at the end of this document).
The immersion length may affect the accuracy of
the sensors. If it is too low, an error might be gen-
erated in the measurement of the temperature, due
to the lower temperatures of the process fluid near
the walls, and to the heat transfer which occurs
through the sensor stem.
The incidence of such error could be not negligible
if there is a big difference between the process and
the ambient temperature.
To avoid this source of inaccuracy, probes with low
diameter must be employed, and the immersion
length (L) should be, if possible, at least about 80
mm. In small pipes, the axis line of the duct must
be reached, and even slightly exceeded, by the tip
of the probe (see figure 3).
Insulation on the outer part of the sensor reduces
the effect of the low immersion. Another solution
could be a tilted installation (see figure 2).
Fig. 2: General installation solutions
In case of two-phase flows, attention should be paidin the choice of the measurement point, which may cause
fluctuations in the detected temperature value.

Suitable solutions for the installation of the sensors in small pipes are shown in figure 3.
In hygienic applications, a good, strict, installation rule consists in not to leave any dead spaces along the flow
of the process fluid.
The required flush-mounting can be achieved by the connection Varivent®, G1" LiquiphantM type (+ purpose
built adaptor).
The clamp flanges can also partly fulfil this requirement, if the Tri-Clamp®components 7IMPS or TL7IWWMS
(Instrument Tees) are used (see the related figure 4).
Fig. 3: Installation solutions in small pipes
For other connection arrangements, the diagram in figure 2 should be followed [h <= d/2].
For weld-in connections, care should be taken by the user in the execution of the welding on the process side
(suitable weld material, welding radius > 3 mm, absence of pits, folds, crevices, …).
The use of purely threaded, Ingold and metal-to-metal joints is not recommended by some hygienic design
standards(i.e. 3-A®Standard 74-02 and Document 8 from EHEDG). This is the reason why E+H Temperature
division doesn't suggest those solutions in "sanitary" applications. Moreover often metal-to-metal couplings can
only be used effectively once. Regarding corrosion, the basic material of the wetted
parts (SS 316L/1.4435) is capable to tolerate com-
mon corrosive media up to high temperatures.
When disassembling the sensors, new gaskets equiv-
alent to the originals and specific torques must be
employed for the re-assembling procedure. This will
ensure the stated IP (Ingress Protection) grade of the
enclosures.
To avoid problems due to condensation when the
ambient has ahigh humidity rate and the process is at
a low temperature, a plastic housing (i.e. model
TA20B) can be an effective choice.

System components
Housing The housing which contains the electric terminals or the transmitter, can be of different types and materials
(plastic, painted aluminium, stainless steel). The way in which it fits to the rest of the probe and the gland for
the cable entry ensures an IP grade of 65 at minimum (also refer to the figure below). All the heads supplied
have internal geometry according to DIN 43729 standard (form B), and thermometer connection M24x1.5.
Version IP66/IP67 of head type TA20A is the basic E+H aluminium housing for temperature sensors. It is sup-
plied in the E+H corporate colours, without any extra charge.
Head TA20B is a blackor white polyamide housing, sometimes defined with the code BBK in the Temperature
market.
In TA21E a screw cap is employed and is attached to the head body by a chain.
Head type TA20D (aluminium), also referred to as BUZH, is able to contain a terminal block and a transmitter,
or two transmitters at the same time.
HeadTA20JisthestainlesssteelhousingwithE+Hcorporatedesign.ItcanalsobeprovidedwithaLCDdisplay
(4 digits), operating with 4…20 mA transmitters.
TA20R is the head suggested by E+H Temperature division for hygienic applications, because it comes in stain-
less steel and because of its "clean" design.
TA20W (BUS type) is a round grey coloured head made of aluminium, with a clip for the cap closure.
The cable glands M20x1.5 and Pg 16 supplied with the housings, accept cable diameters from 7 to 12 mm.

• TMT 180 PCP 4…20 mA
• TMT 181 PCP 4…20 mA
• TMT 182 Smart HART®
• TMT 184 PROFIBUS-PA®
TMT 180 and TMT 181 are PC Programmable transmitters. TMT 180 can be supplied in a version with
improved accuracy (0.1°C vs. 0.2°C) in the bandwidth -50…250°C, and a model with a fixed measurement
range (specified by the customer in the order phase) is also available.
TMT 182 output consists of 4…20 mA and HART®superimposed signals.
For TMT 184, with PROFIBUS-PA®output signal, the communication address can be set via software or by
means of a mechanical dip-switch. The customer may specify the desired configuration in the order phase.

Extension neck Manufactured in stainless steel, the extension neck (part between the process connection and the housing) is
made up of a tube with a standard diameter of 15 mm and is 82 mm in length.
The upper connection of the neck permits adjustments to the orientation of the sensor head.
Process connection This can be chosen form the following types:
Standard connections are available in several sizes. Others (i.e. Neumo, APV) are available on request.
The process connection iscontinuously welded on the probe oron the well soas to obtain aminimum welding
radius of 3.2 mm between the lower surface of the connection and the sensor stem (according to EHEDG and
3-A®standards).
Please refer to paragraph on "Accessories" for information regarding availability of welding adaptors.
The Varivent®connections must be used with dedicated Tuchenhagen®in-line components or tank adaptors.
For Varivent®flanges with small nominal diameter, maximum immersion lengths for usual applications are
listed in the following table (also refer to figure 3).
Please be aware that in the past the Varivent®connection DN25 has been used also for pipes with nominal
diameter DN32.

Probe In TR 45, the measuring probe is constituted by a mineral insulated insert positioned inside the thermowell.
For its replacement, the insert length (IL) must be chosen depending on the immersion length (L) of the ther-
mowell. Should a spare part be required, please refer to the following table:
In TR 44 the protection well and the sensing part cannot be separated.
Theimmersionlengthisavailableinsomestandardvaluesoritcanbesuppliedin a "customized"versionwithin
a range (please see the product structures in the last pages of this document). Up to a length of 50 mm the TR
44 may have a probe with 6 mm diameter only.
For special versions of TR 45, where the immersion is shorter than 30 mm, the diameter of the thermowell, as
in the reduced tip, should be 5.3 mm.
The starting material for the wetted parts can be supplied in compliance of Basler Norm 2 (BN2), which
imposes a limited ferrite content and consequently enhances corrosion resistance, on request. In some sensor
configurations, the compliance with the requirements of BN2 can also be assured after the welding and
machining operations, that is in the finished product. The surface roughness (Ra) of the wetted parts is supplied
down to 0.4 mm. Surface roughness below 0.4÷0.5 mm has not been proven to be advantageous in hygienic
applications. Electro-polishing is an electrolytic treatment of the metal surface, which results in it being
cleaned, levelled and passivated.
To improve the heat transfer between the well and the internal sensing insert in the TR 45, a thermo-conduc-
tive compound can be fitted inside the thermowell, on request. The compound should not be requested for
immersion lengths longer than 300 mm, and where it would be used in temperatures of over 200°C.

• EHEDG Type EL certification (TNO report n. V3912). EHEDG accepted process connections are: Varivent®,
IDF type ISO 2853, APV (acc. DIN 11864), APV Inline, DIN 11851 (only in combination with EHEDG cer-
tified gasket from Siersema), Suedmo, Naue, Neumo.
•3-A
®Authorization no. 1144 for the declaration of compliance with standard 74-02. 3-A®accept all the
mentioned process connections.
Ex approval ATEX certificate KEMA 01 ATEX1169 X (1 or 1/2 GD IIC EEx ia T6...T1 T85...450°C) for TR 45.
Material certification The 3.1.B material certificate, according to standardEN 10204, is selectable directly from the sale structure of
the product. Other types of material certifications can be requested separately.
The "standard" one is a simplified and cost-effective version, in which the documentation about the origin of
the materials employed refers to each sensor. The "labelled" version also has a specific marking that relates to
the wetted parts of the sensor and ensures that the relevant data are placed in the archives by means of the
serial number of the thermometer.
Test report & calibration Regarding testing and calibration, the "inspection test report" consists of a declaration of conformity with the
essential points of standard DIN EN 60751.
The "Factory calibration" is carried out in the E+H EA (European Accreditation) accredited laboratory for tem-
perature calibrations, following an internal procedure. A calibration performed according to an EA accredited
procedure (SIT calibration) may be requested separately.
The calibration is executed on the thermometer insert, when that has been installed in the sensor (TR 45).
For TR 44 a minimum immersion length (120 mm) is required to ensure a precise calibration.
With the Sensor Matching Calibration, a preliminary Factory calibration of the sensor is carried out and subse-
quently the output curve of the transmitter is adjusted in order to minimize measurement error. In this way
some of the sensor errors (probe or "loop" probe+transmitter) are compensated for through the transmitter.
Further details
Maintenance Omnigrad M thermometers do not require specific maintenance. For the models supplied with process con-
nections including seals, the integrity of the sealing ring should be checked regularly and it must be substituted
when necessary.
In case of ATEX-certified components (transmitter, insert), please refer to the relevant documentation (see the
code at the end of this document).
Delivery time For small quantities (about 10 units) and standard options, generally 10 days.
