Abstract

Device allowing preservation of the operation of a thermocouple. The invention relates to a device for protecting the conductors of a thermocouple. It consists, according to Figure 2: - either of a metal tube 1 of length appropriate to the use, crimped onto the conductors 2 and 3; - or of a covering 1 of length appropriate to the use, obtained by moulding or coating ceramic or synthetic material onto the said conductors subsequently enveloped in an insulator 4. A conventional sheath is shrunk over the assembly in order to protect it.

Description

La presente invention concerne un dispositif protéqe@nt les couples thermo-électriques. The present invention relates to a device which protects the thermoelectric couples.

Le t@ermocouple tr@ditionnel comporte un couple enrobe d'un isolant, l'ensemble gaine et rétreint dans un tube de métal. The traditional t @ ermocouple comprises a couple coated with an insulator, the sheath assembly and shrunk in a metal tube.

Ces thermocouples traditionnels présentent un caractére technique aléatoire important selon la temperature d'emploi. These traditional thermocouples have an important random technical character depending on the temperature of use.

Pour le thermocouple nickel Chrone, Nickel Aluminium, aux phénomènes de dilatation se superpose une modification de structure. On est en présence d'un eutectique. For the nickel Chrone, Nickel Aluminum thermocouple, a structural modification is superimposed on the expansion phenomena. We are in the presence of an eutectic.

Considérons des électrons en mouvement dans un conducteur
Chromel + revêtu d'une couche isol@nte magnésie et qui forme ce qu'on appelle une barrière de potentiel sur laquelle les électrons ne peuvent que rebondir.Consider electrons moving in a conductor
Chromel + coated with an insulating layer of magnesia and which forms what is called a potential barrier on which the electrons can only bounce.

Si on considère l'onde de Broglie associée à l'électron, cette onde n'est pas arrêtée Il y a franchissement de la barrière de potentiel. Tout se passe comme s'il y avait des tunnels dans la couche isolante à travers laquelle passe de la matière. If we consider the Broglie wave associated with the electron, this wave is not stopped. There is crossing of the potential barrier. Everything happens as if there were tunnels in the insulating layer through which material passes.

On peut considerer une particule comme phénomène corpusculaire et ondulatoire pour une énergie cinétique suffisante superieure à une énergie de seuil Eo. We can consider a particle as a corpuscular and wave phenomenon for a sufficient kinetic energy greater than a threshold energy Eo.

flans la couche isolante, il y a des milliards de micro-etats de métal, ce qui conduit à mettre à la sasse le thermocouple traditionnel. In the insulating layer, there are billions of micro-states of metal, which results in the traditional thermocouple being sifted.

Le dispositif selon l'invention permet de remédier à cet inconvénient. The device according to the invention overcomes this drawback.

Selon l'invention on résoud le problème en rw;ant inter médiairemen; les conducteurs du Shermo-couple.  According to the invention the problem is solved by rw; ant inter mediately; drivers of the Shermo-couple.

Le revêtement consiste dans un mode de realisation en un tube métallique à celui de chacun des conducteurs de diamètre légèrement supérieur, qui sera étroitement adapsé aux dits conducteurs par rétreint. The coating consists in one embodiment of a metal tube to that of each of the conductors of slightly larger diameter, which will be closely adapted to said conductors by shrinking.

Selon un autre mode de réalisasion le revêtement intermé- diaire sera réalisé à partir de céramique ou matière synthétique directement par coulage ou par enduction,
La présence Invention est illustrée par le dessin annexé dans lequel:
- la figure I représente une vue déployée des conducteurs revêtu et la figure 2 représente l'ensemble du thermo-couple protégé selon l'invention.According to another embodiment, the intermediate coating will be produced from ceramic or synthetic material directly by casting or by coating,
The invention presence is illustrated by the appended drawing in which:
- Figure I shows a deployed view of the coated conductors and Figure 2 shows the entire thermocouple protected according to the invention.

Comme on peu; le voir sur les figures les conducteurs (2) et (3) reliés par la soudure chaude sont d'abord revêtus par une couche (I) soi; ae métal, soit de céramique, soi; d'un matériau synthétique. As we can; see in the figures the conductors (2) and (3) connected by the hot solder are first coated with a layer (I) itself; metal, or ceramic, itself; synthetic material.

Les conducteurs ainsi protégés sont enrobés selon les mé thodes classiques d'un isolant approprié (4) puis recouverts dune gaine classique (5). The conductors thus protected are coated according to conventional methods with an appropriate insulator (4) and then covered with a conventional sheath (5).

Cette nouvelle protection sora quant aux matériaux, déter- minée, en fonction de l'utilisation recherchée, de. la nature aes conducteurs et de l@isolant.  This new protection for materials, determined, depending on the desired use, of. the nature of the conductors and of the insulation.

Le dispositiz de 1 invention peut entre employé dans tous les domaines flans lesquels l'application drune F.E.M. (force electro-motrice) doit determiner une temperature et inversement, une temperature choisie induit la F.E.M. recherchée.  The device of the invention can be used in all of the blank areas in which the application of a F.E.M. (electro-motive force) must determine a temperature and conversely, a chosen temperature induces the F.E.M. wanted.
