Function and system design

Measuring principle In RTD (Resistance Temperature Detector) thermometers the sensing element consists of an elec-trical resistance with value of 100 Ω at 0°C (called Pt 100, in compliance with standard DIN EN60751), which increases at higher temperatures according to a coefficient characteristic of theresistor material (Platinum).

Overall design The temperature sensors Omnigrad M TR 44 and TR 45 are constituted by a measurement probe,with (TR 45) or without (TR 44) a protection well, and a housing (head), which may contain a trans-mitter or the terminals for the electrical connection.In TR 45 the probe is a sensing insert, placed inside the thermowell and spring loaded on the bot-tom of it, so as to improve the heat transfer.The sensing element (Pt 100), like in TR 44, is positioned close to the tip of the probe.The thermowell (TR 45) is obtained from a 9 mm diameter pipe. The final (sensing) part can bestraight, tapered, that is with diameter smoothly decreased by means of a hammering procedure,or reduced (stepped). For TR 44, the sheath of the probe is obtainedfrom a 8 mm or from a 6 mm pipe. In the case of8 mm, the final (sensing) part is always withreduced (stepped) diameter. In the case of 6mm, the probe pipe is always straight. The probe (TR 44) or thermowell (TR 45) can beinstalled on the plant (pipe or vessel) by meansof a hygienic process connection, which can bechosen among the most common types (seesection "System components").For both TR 44 and TR 45 the construction, exe-cuted according to 3-A® and EHEDG design cri-teria, allows the sensor to withstand the stressescaused by CIP (Cleaning In Place) and SIP (Ster-ilization In Place) processes.The electrical structure of the instruments com-plies always with the rules of DIN EN 60751standard.The housing can be of different types and mate-rials (plastic, painted aluminium, stainless steel).Its fitting to the rest of the probe and the gland forthe cable entry, assure an IP (Ingress Protection)grade of 65 at minimum.

Electronics

The wanted type of output signal can be obtained by choosing the right head-mounted transmit-ter. Endress + Hauser provides state-of-the-art transmitters (iTemp® series) built in 2-wire technologyand with 4…20 mA, HART® or Profibus-PA® output signal. All the transmitters are easily program-mable with a personal computer, by means of the public domain software ReadWin® 2000 (for4…20 mA and HART® transmitters) or the software Commuwin II (Profibus-PA® transmitters).The HART® transmitters can be programmed also by means of the handheld operating moduleDXR 275 (Universal HART® Communicator).A PCP (4…20 mA) model (TMT 180) is available with enhanced accuracy, particularly advisablefor hygienic applications. In the case of Profibus-PA® transmitters, E+H suggests the use of Profibus dedicated connectors:the Weidmüller type (Pg 13.5 M12) is provided as standard option.For detailed information about transmitters, please refer to the specific concerned 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 theterminal block to a remote converter (i.e. DIN rail transmitter).

The "4 wires" configuration assures no additionalerrors in case of long connecting cables (withouthead-mounted transmitter); with the "4 wires" config-uration, generally speaking, there is a higher guar-antee of accuracy.

Measurement range • TR 44 -50…250°C• TR 45 -50…400°C

Response time Test in water at 0.4 m/s (according to DIN EN 60751; 23 to 33°C step change):

Insulation Insulation resistance between terminals and probe sheath more than 100 MΩ at 25°C(according to DIN EN 60751, test voltage 250 V) more than 10 MΩ at 300°C

MTBF It is heavily influenced by the operating conditions (high pressure, vibrations, shocks, thermalshocks, corrosion, …) of the sensors.For a normal use, a calculation made according to MIL-HDBK-217F, gives as result a value higherthan 100 years in the case without built-in electronics, and more than 20 years with a head-mounted transmitter (35 years with TMT 181).

Self heating Negligible when E+H transmitters are employed.

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, aregenerally not supplied with the sensors, and are on the customer's responsibility (EHEDG and 3-A® requirements must be fulfilled). The only exception are the G1" and the Ingold connections, for which it is possible to provide thesensor with the adapter to be welded on the plant. Furthermore the Ingold connection and the G1" Liquiphant M type counterpart are supplied withthe necessary sealing o-rings.As a general rule, the sensors should be installed in a manner which does not adversely affecttheir cleanability.

In case of ATEX certified components (transmitter, insert), please refer to the specific documen-tation (see the code at the end of this document).The immersion length may have an influence on the accuracy of the sensors: if it is too low, anerror might be generated in the measured temperature, due to the lower temperatures of the proc-ess fluid near the walls, and to the heat transfer which occurs through the sensor stem. The incidence of such error can be not negligible if the difference between the process and theambient temperature is big.To avoid this source of inaccuracy, the immersion length (L) should be, if possible, at least 90÷120mm. In pipes with little diameter, the axis line of the duct must be reached, and even slightlyexceeded, 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). Attention should be paid in the choice of the measurement point in case of two-phase flows, whichmay cause fluctuations in the detected temperature value. For installation of the sensors in small pipes, suitable solutions are shown in figure 3.

Figure 2. General installation solutions.

In hygienic applications, a good, strict, installation rule consists in not to leave any dead spacesalong the run of the process fluid. For this aim, the flush-mounting is allowed by the connectionsVarivent, G1" Liquiphant M type (+ purpose built adapter) and Ingold (+ purpose built adapter).Also the clamp flanges can partly fulfil this requirement, if the Tri-Clamp® components 7IMPS orTL7IWWMS (Instrument Tees) are used (see the related figure 4).

For other connection arrangements, the scheme illustrated in fig. 2 should be observed [h <=d/2].For weld-in connections, care should be taken by the user in the execution of the welding on theprocess side (suitable weld material, welding radius > 3 mm, absence of pits, folds, crevices, …).Purely threaded and metal-to-metal joints are dis-couraged by some hygienic design standards (i.e.3-A® Standard 74-01 and document 8 from EHEDGrespectively). This is the reason why E+H Tempera-ture division doesn’t suggest those solutions in "san-itary" applications. Moreover often metal-to-metalcouplings can be used properly only one time.Concerning corrosion, the basic material of the wet-ted parts (SS 316L/1.4435) is capable to toleratecommon corrosive media up to high temperatures.The gaskets supplied with the Ingold process con-nection and with the G1" Liquiphant M type weld-inadapter, besides CIP and SIP-proof, resist to a widevariety of aggressive substances. For particularapplications, please ask to the E+H service.In case of disassembling of the sensors, new gas-kets equal to the originals and specific torques mustbe employed for the re-assembling procedure, toassure the stated IP (Ingress Protection) grade of theenclosures. When the ambient has a high humidity rate and theprocess is at low temperature, a plastic housing canbe an effective choice (i.e. model TA20B) to avoidproblems due to condensation.

System components

Housing The housing which contains the electric terminals or the transmitter, can be of different types andmaterials (plastic, painted aluminium, stainless steel). Its fitting to the rest of the probe and thegland for the cable entry, assure an IP grade of 65 at minimum (see also the figure below). All the supplied heads have internal geometry according to DIN 43729 standard (form B), andthermometer connection M24x1.5. Head type TA20A is the basic E+H aluminium housing for temperature sensors, provided in theE+H corporate colours, without supplementary charges in the version IP66/IP67.Head TA20B is a polyamide housing, black or white, sometimes defined with the code BBK in theTemperature market. In TA21E a screw cap is employed, joined to the head body by a chain.Head type TA20D (aluminium), called also BUZH, is able to contain a terminal block and a trans-mitter at the same time, or two transmitters. Head TA20J is the stainless steel housing with E+H corporate design, and can be provided alsowith a LCD display (4 digits), operating with 4…20 mA transmitters.TA20R is the head suggested by E+H Temperature division for hygienic applications, due to itsmaterial (stainless steel) and its "clean" design.TA20W (BUS type) is an aluminium round-shaped grey head, with a clip for the cap closure.

Head transmitter The available head-mounted transmitters are (see also the section "Electronics"):• 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 versionwith a better accuracy (0.1°C vs. 0.2°C) in the bandwidth -50…250°C; a model with a fixed meas-urement range (defined by the user in the order phase) is available too.TMT 182 output consists of 4…20 mA and HART® superposed signals.For TMT 184, with Profibus-PA® output signal, the communication address can be set via softwareor by means of a mechanical dip-switch: the user may ask for the desired configuration in theorder phase.

Figure 6. TMT 181.

Extension neck The extension neck (part between the process connection and the housing), built from stainlesssteel, is constituted by a tube with standard diameter of 15 mm and length 82 mm. For the Ingold process connection, this dimension of 82 mm is not sufficient, and a greater lengthmust be specified by the user through the "8" digit in the product order code.

Process connection It can be chosen among the types:

The connections are supplied in several sizes. Others (i.e. Neumo, APV) are available on request.The process connection is continuously welded on the probe or on the well in such a way to obtaina welding radius of 3.2 mm at minimum, between the lower surface of the connection and the sen-sor stem (requirement of EHEDG and 3-A® standards). The Ingold connection is supplied with the sealing o-ring mounted on, whose material (silicone)is in compliance with FDA CFR Title 21, § 177.2600 (max temperature 230°C).Concerning the available welding adapters, please see the paragraph "Accessories".The Varivent® connections must be used with dedicated Tuchenhagen® in-line components ortank adapters; for Varivent® flanges with small nominal diameter, the maximum immersion lengthsfor usual applications are listed in the following table (see also figure 3)

Please be aware of the fact that in the past the Varivent® connection DN25 has been used also forpipes with nominal diameter DN32.

Probe In TR 45 the measuring probe is constituted by a mineral insulated insert positioned inside thethermowell. For its replacement, the insert length (IL) must be chosen depending on the immersion length (L)of the thermowell; in case of need for a spare part, please refer to the following table:

In TR 44 the protection well and the sensing part cannot be separated.The immersion length is available in some standard values, or it can be choosen "customized"within a range (please see the product structures in the last pages of this document). For special versions of TR 45, with immersion shorter than 30 mm, the diameter of the thermowellshould be 5.3 mm, as in the reduced tip.On request the starting material for the wetted parts can be supplied in compliance with BaslerNorm 2 (BN2), which imposes a limited ferrite content, in order to obtain an improved corrosionresistance. For some sensor’s configurations the compliance with the requirements of BN2 canbe assured also after the welding and machining operations, that is on the finished product.The surface roughness (Ra) of the wetted parts is supplied down to 0.4 µm. A roughness below0.4÷0.5 µm is not demonstrated to have advantages for hygienic purposes.Electropolishing consists in an electrolytic treatment of the metal surface, which leads to a clean-ing, levelling and passivation of it.In TR 45 a thermically conductive compound can be requested inside the thermowell, to improvethe heat transfer between the well and the internal sensing insert. The compound shouldn’t berequested for immersion lengths longer than 300 mm, and used over 200°C.

Certifications

Certifications from exter-nal bodies

• EHEDG Type 1 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 certified gasket from Siersema), Suedmo, Naue, Neumo.

• 3-A® Authorization no. 1144 for the declaration of compliance with standard 74-01.• ATEX certificate KEMA 01 ATEX1169 X (1 GD IIC EEx ia T1÷T6) for TR 45.

Manufacturer’s certifica-tions

The 3.1.B material certificate, according to standard EN 10204, is selectable directly from the salestructure of the product. Other kinds of material certifications can be requested separately. The "standard" one is a simplified and cost effective version of the certificate, in which the docu-mentation about the origin of the employed materials refers to each sensor. The "labelled" versionhas in addition a specific marking relating to the wetted parts of the sensor, and assures theplacement in the archives of the relevant data by means of the serial number of the thermometer. Concerning tests and calibration, the "inspection test report" consists in a declaration of conform-ity to the essential points of standard DIN EN 60751.The "Factory calibration" is carried out in the E+H EA (European Accreditation) accredited labo-ratory for temperature calibrations, following an internal procedure. A calibration performedaccording to an EA accredited procedure (SIT calibration) can be requested separately.The calibration is executed on the thermometer insert, when that is present in the sensor (TR 45).For TR 44 a minimum immersion length (90 mm) is needed to assure a correct calibration.With the Sensor Matching Calibration, a preliminary Factory calibration of the sensor is executed,and subsequently the output curve of the transmitter is adjusted in order to minimize the meas-urement error. In this way some of the errors of the sensor (probe or "loop" probe+transmitter) arecompensated by means of the transmitter.

Maintenance Omnigrad M thermometers don't need a specific maintenance. For the models supplied withprocess connections including seals, the integrity of the sealing ring should be checked regularlyand it must be substituted when necessary. In case of ATEX certified components (transmitter, insert), please refer to the specific documen-tation (see the code at the end of this document).

Delivery time For small quantities (about 10 units) and standard options, from 5 to 20 days depending on therequested configuration.
