1. General notes1.1 Goods incoming

Upon receipt of the goods, they should be inspected immediately for external damage. Defects in the pa-ckaging must be reported to the carrier immediately and acceptance must be refused.

Should the product be damaged after unpacking, this must be immediately reported in writing to thermo-control. The complaint can be accepted no later than 5 days after receipt of the goods.

The delivery documents show whether additional transport insurance has been taken out. If this is the case, thermo-control must be informed immediately so that the damage can be asserted against the insurance company.

1.2 Inhalt

All thermocouples are delivered with a transport protection. This serves to protect the ceramic tubes against mechanical stress during transport.

(1) Thermoelement

(2) Plaxiglas Transportrohr ∅30 mit Kleinflansch Aufsatz

(3) Dicht- und Zentrierring

(4) Spannring Aluminium

For new parts, a Certificate of Calibration for each thermocouple for the built-in thermocouple and a Cer-tificate of Conformity in a DIN A4 envelope are affixed to the inside of the box with a CERTIFICATE sticker.

1.3 Anwendbare Produkte

Die folgende Gebrauchsanleitung ist generell für Vakuum-Thermoelemente mit Kleinflansch-Anschlüssen gültig.

1.5 Transport protection

The products are secured with different means during transport. The correct handling of disassembling the transport protection guarantees the safety of the product.

In essence, two methods are in use:

• Securing with plexiglass tube and filling material

• Securing with stainless steel tube and PVC net hose

1.5.1 Transport protection with Plexiglass tube and filling material

Thermocouples with small flange or threaded connections are shipped in a Ø30mm Plexiglas tube. In the plexiglass tube, the ceramic tubes of the thermocouple are fixed against movement by a filling material, usually corundum or walnut shell granules. The open end of the tube is provided with a blue cap.

Please remove the protection using following procedure:

• Remove the blue cap

• Completely remove / pour filling material out of the Plexiglas tube

• Pull the thermocouple out of the Plexiglass tube

Important note: Not following above procedure will damage the thermocouple protection tube.

1.5.2 Transport protection with stainless steel tube and PVC mesh hose

This method is used for thermocouples with holding tube with a metallic transport tube. The tube has a diameter of Ø18mm and covers the ceramic protective tubes. The ceramic tubes are covered with a PVC mesh hose to protect them from shocks. The hose can protrude a few centimeters out of the transport tube and is usually colored blue.

The transport tube is removed by pulling out in the direction of the longitudinal axis of the thermocouple. Lateral movements or rotations can lead to breakage of the ceramic tubes and thus to the loss of the guarantee.

1.6 Certificate of calibration

Based on the type of product the certificate of calibration can be issued in two variations.

• Standard calibration based on Gold and Palladium fix-point measurements against ASTM E230/E230M with correction values from 500°C to 1500°C in 100K steps.

• Coil calibration in accordance to AMS 2750 from 150°C to 1320°C in 130K steps

1.7 Certificate of conformity

This certificate contains all production details which have been added to the serial number.

This includes:

• Batch number of the sealing mat used

• Used blank (process connection with potted ceramic protection tubes)

• Test data and result of the helium leak test

Example: 8-050301-0600KF25

Thermocouple for vacuum systems up to 5 bar atmospheric pressure with 2 x Type S thermocouples + 1 empty test tube, with a nominal length of 600 mm and ISO 2816 small flange DN25.

A protective tube serves as a test tube into which a test thermocouple can be inserted. As a result, this thermocouple can be checked for any deviations at any time. Also, if the thermocouple is installed in the oven, the measurement can be performed. Due to the separate guidance of the thermocouples, the test measurement does not affect the built-in thermocouples. In addition, the thin-walled construction makes the thermocouple more tolerant of faster insertion speeds.

(*)Important noteUsing the small flange fitting at pressures above 5 bar special seal rings and clamps need to be used to ensure a safe production.

Vacuum thermocouples with small flange fittingCommissioning of the thermocouple

3. Commissioning of the thermocoupleThe installation and commissioning of the thermocouple may only be carried out by suitably trained specia-lists. For all indirect and direct damages caused by improper installation, thermo-control assumes no liability.

3.1 Connection mechanical

Loosen the previous small flange connection at the furnace connection. Check the sealing surfaces on the furnace connection and the thermocouple for dents, scratches and dirt. Clean soiling with a clean cloth and isopropanol. Also check the seal for integrity or brittleness. The thermocouple comes with a new sealing and centering ring, which you can also use.

The strain relief of the cable guide should point as far down as possible.

Important!Make sure the feedthroughs of the outer and inner chambers are coaxial. The ceramic protective tubes should be free of stress in the bushings.

Security noteThe use of vacuum grease on the seals is not permitted.

For furnace pressures above 5 bar additional mechanical safeguards must be installed to prevent the thermocouple from escaping!

3.2 Connection electric

The compensating cable of the corresponding type of thermocouple is routed through the M20x1 cable guide into the connection head and connected to the existing terminals, preferably with nickel-plated core sleeves. Here, the positive wire to the colored terminal and the negative wire to the wise terminal to connect.

If the colored marking is no longer recognizable, the negative wire on thermo-control thermocouples can be recognized by the fact that it is thicker than the positive wire.

3.3 Completing the preparations

The thermocouple is ready for operation after successful mechanical and electrical connection. Thereafter, the correction values from the supplied certificate should be entered into the furnace control.

To avoid measurement errors, the cover of the connection head must always be closed, so that a constant temperature can be maintained within the head, which is not disturbed by air circulation.

4. Troubleshooting4.1 No signal

If the thermocouple shows no temperature despite correct start-up, the thermocouples used should be checked for electrical connectivity. If this is the case, the remaining measuring section should be examined for an interruption, for example cable breakage. If it is suspected that the fault is with the thermocouple, the thermocouple must be sent in for inspection and an accurate error analysis must be carried out.

4.2 The thermocouple always reads 30°C (± 10 °C)

In this case, there is a short circuit of the thermocouple wires in the connection head and the temperature of the connection head is measured. This extremely rare error can only occur when the thermocouple is first installed. Should the suspicion of the inspection prove that this short circuit was caused by thermo-control,

the repair will of course be handled as a warranty case.

4.3 The thermocouple indicates a falling temperature when heated

The reason for such a behavior is usually a wrong polarity of the compensation line with the thermo wires. If there is no change despite the color match (white clamp and orange / red on orange clamp), the silicone insulating tubing has been misfeeded. This, extremely rare, production-related error can be corrected by simply reconnecting the occupancy. It is recommended to remove the silicone tubes with the thumbnail and replace them. Another indication is the different thickness of the thermo wire in which the thicker is always the negative wire.

4.4 The thermocouple drifts

Thermo-control thermocouples never drift due to the different thickness of the thermo wires. However, if a drift is used, it must be checked to what extent external damage, mechanical or chemical, can be detected. If no external influences are visible, the thermocouple should be returned.

NotePtRh-Pt thermocouples always drift downwards, indicating a lower temperature than the actual one. If the new, apparently drifting, thermocouple shows more than the built-in, it is more likely that the built-in thermocouple have a certain drift.

TipOrder a suitable test thermocouple for the thermocouple. This is made from the same wire batch. Since it is not constantly exposed to the temperature drift is unlikely here.

4.5 Re-Calibration

Each thermo-control thermocouple has a separate, empty thermowell in which a controlling thermocouple can be inserted. The access to the empty tube is available in the connection head.

Due to this design, the thermocouple does not have to be removed!

5. Safety instructions

Do not repair the thermocouple yourself!In this case, the warranty expires immediately and there is an increased risk that the oven and the batch will be damaged. Damaged thermocouples should be returned for inspection to investigate the possibility of repair.

Notes on installationPlease note that the feedthroughs from the oven to the chamber are coaxial with each other! Due to the thin design of the ceramic protective tubes they are easily bendable, so that a slight shift of the coaxiality is initially not noticed. However, once the connection is tightened it can come to so-called root breaks.

Note when used in pressure chambersWhen using thermocouples in pressure atmospheres> 5bar, the fastening via the respec-tive process connection must additionally be secured against loosening, for example by means of a bracket or a chain.

Note on the warrantyAll thermocouple rotection tubes are tested for vacuum tightness prior to manufacture with a helium leak test. Likewise, attention is paid to the highest purity during production.

The resulting quality allows a warranty period of 4 years from delivery against drift and thermal wire breakage.

The warranty is void if a ceramic protective tube is mechanically and / or chemically attacked and / or damaged by external influences. This also expires in case of third-party repair, changes in the construction, if this has not been clarified in writing with thermo-control. For damages of any kind as a result of improper attachment or use, the thermo-control Körtvélyessy GmbH assumes no liability.

6. PackagingIf this is your first thermo-control thermocouple, you should unpack the box it was delivered to. This ensures that in the event of a return, the thermocouple survives the transport undamaged. If, after many years of operation, the box is no longer available, you should consider the following recommendations for shipping.

6.1 Box material

The box should consist of at least 2-corrugated cardboard box 2.3 strength. Wooden or stiffened plastic packaging is also suitable.

6.2 Filling material

thermo-control has been successfully using paper paper rolls (wrapping paper or similar material) for over 3 decades, with the nodule size being about a rumpled newspaper page. Alternatively, rolls of paper pads can be used on which the products are placed.

Styrofoam flakes (or similar material) are not allowed as a filler!Styrofoam is too hard and does not dampen jerky movements sufficiently, moreover, the small particles do not fix the part sufficiently against slipping. Machine made paper pads are also suitable, as long as a sufficient suspension can be guaranteed.

6.3 Loading

The connection head should be placed in the middle and at least 10cm from the box walls. If there are two parts, the connection heads are to be packed opposite and care must be taken that both parts can not collide.

6.4 Request a new box

At http://www.thermo-control.com/en/support/index.php you can request a new box of filler suitable for your product for free.

7. Hinweise zur GarantieAlle Schutzrohre der Thermoelemente werden vor der Fertigung auf ihre Gasdichtigkeit mit einem Helium-Leck-Test geprüft. Ebenso wird bei der Fertigung auf höchste Reinheit geachtet.

Die dadurch erzielte Qualität ermöglicht eine Garantiezeit von 4 Jahren ab Lieferung gegen Drift und Ther-modrahtbruch.

Die Garantie erlischt, wenn ein keramisches Schutzrohr durch Fremdeinwirken mechanisch und/oder che-misch angegriffen und/oder beschädigt wird. Ebenso erlischt diese bei Fremdreparatur, Veränderungen der Konstruktion, wenn diese nicht mit thermo-control schriftlich geklärt wurde. Für Schäden jeder Art in Folge von unsachgemäße Befestigung oder Verwendung übernimmt die thermo-control Körtvélyessy GmbH keine Haftung.

8. Verpackung Wenn dies Ihr erstes thermo-control Thermoelement ist, sollten Sie die Kiste, in der es angeliefert worden ist aufheben. So ist sichergestellt, dass im Falle einer Rücksendung das Thermoelement den Transport unbeschädigt übersteht. Sollte nach vielen Jahren Betrieb die Kiste nicht mehr vorhanden sein, sollten Sie folgende Empfehlungen für den Versand berücksichtigen.

8.1 Kistenmaterial

Die Kiste sollte mindestens aus 2-welligem Pappkarton 2.3 Festigkeit bestehen. Holz- oder versteifte Kunst-stoffverpackungen sind ebenfalls geeignet.

8.2 Füllmaterial

thermo-control verwendet seit über 3 Jahrzehnten erfolgreich Papierknöllchen aus Papier (Packpapier oder ähnliches Material), wobei die Knöllchengröße etwa eine geknüllte Zeitungsseite sein sollte. Alternativ können auch Rollen aus Papierpolster verwendet werden, auf denen die Produkte gelegt werden.

Styroporflocken (oder ähnliches Material) sind als Füllstoff nicht zu-lässig! Styropor ist zu hart und dämpft ruckartige Bewegungen nicht ausreichend, zudem fixie-ren die kleinen Partikel das Teil nicht ausreichend gegen ein Verrutschen. Maschinell herstellte Papierpolster sind ebenfalls geeignet, solange eine ausreichende Federung gewährleistet werden kann.

8.3 Beladung

Der Anschlusskopf sollte mittig und mind. 10cm von den Kistenwänden platziert werden. Bei zwei Teilen sind die Anschlussköpfe entgegen gesetzt zu packen und es ist darauf zu achten, dass beide Teile nicht zusammenstoßen können.

Neuen Karton anfordernSie können unter http://www.thermo-control.com/de/support/index.php eine neue Kiste mit Füllmaterial passend zu Ihrem Produkt kostenlos anfordern.
