Abstract

Temperature measurement sensor which can be adjusted as a function of the depth of the housing in which it is to be mounted, in order to keep its active part in close contact with the heated mass. The sensor according to the invention comprises a protector 1 held in the housing by a spring 2, the sensor being immobilised by means of another spring 9 which ends in a pin, mounted on the base 7 screwed into the heated mass 6; the pin passes diametrically through the lower cylindrical area 22 of the shoulder 7 and passes between two turns of the spring 2, whose turns are not contiguous, preventing the spring 2 from relaxing and forcing it to exert its pressure on the protector 1 held against the inmost end of the housing.

Description

L'invention a pour objet un capteur de température ajustable en fonction de la profondeur du logement dans lequel il doit etre monté pour assurer ainsi un contact intime de se partie active avec la masse chauffée afin d'obtenir une résistance thermique aussi faible que possible. I1 est compatible avec les thermocouples, les résistances variables (platine, cuivre, nickel, etc...) ou tout autre élément de mesure présent ou futur pouvant Entre introduit dans le montage tel qu'il est décrit ciaprès. The subject of the invention is a temperature sensor adjustable as a function of the depth of the housing in which it must be mounted so as to ensure intimate contact of the active part with the heated mass in order to obtain a thermal resistance as low as possible. I1 is compatible with thermocouples, variable resistors (platinum, copper, nickel, etc.) or any other present or future measurement element which may be introduced into the assembly as described below.

A cet effet, l'invention concerne un capteur de mesure de température ajustable en fonction de la profondeur du logement dans lequel il doit etre monté afin de maintenir se partie active au contact intime avec la masse chauffée et obtenir ainsi une résistance thermique aussi faible que possible, caractérisé par le fait qu'il comprend un protecteur maintenu en pression mécanique dans le logement par un ressort à spires non jointives, cette pression est maintenue en immobilisant le capteur au moyen d'un autre ressort terminé en épingle, monté sur l'embase vissée dans la masse chauffée, l'épingle traverse à son diamètre l'aire cylindrique intérieure de l'embrase et passe entre deux spires du ressort à spires non jointives,interdisent ainsi au ressort de se détendre et l'obligesnt à exercer sa pression sur le protecteur en butée dans le fond du logement. La mise en place et le démontage du capteur est commode et rapide et ne nécessite pas d'outil lors d'un changement de capteur, l'embase restant solidaire de la messe chauffée. To this end, the invention relates to an adjustable temperature measurement sensor as a function of the depth of the housing in which it must be mounted in order to maintain its active part in intimate contact with the heated mass and thus obtain a thermal resistance as low as possible, characterized in that it comprises a protector maintained under mechanical pressure in the housing by a spring with non-contiguous turns, this pressure is maintained by immobilizing the sensor by means of another spring terminated in a pin, mounted on the base screwed into the heated mass, the pin crosses its internal cylindrical area of its base to its diameter and passes between two turns of the spring with non-contiguous turns, thus preventing the spring from relaxing and forcing it to exert its pressure on the protector in abutment at the bottom of the housing. The installation and disassembly of the sensor is convenient and quick and does not require a tool when changing the sensor, the base remaining integral with the heated mass.

Le capteur comprend à son extrémité sensible un protecteur de forme appropriée qui permet de recevoir l'élément de mesure qui peut Cotre isolé ou non de la masse de ce protecteur. Le protecteur est mis en pression mécanique au fond du logement qui le reçoit sous l'effet du ressort à spires non jointives. Sa terminaison est constituée par les conducteurs électriques qui peuvent etre connectés à une ligne de mesure ou à un instrument de mesure. The sensor comprises at its sensitive end a protector of suitable shape which makes it possible to receive the measuring element which can cut or not isolated from the mass of this protector. The protector is put under mechanical pressure at the bottom of the housing which receives it under the effect of the spring with non-contiguous turns. Its termination consists of electrical conductors which can be connected to a measuring line or to a measuring instrument.

L'embase vissable dans la masse chauffée, et dans l'axe du logement, laisse coulisser librement le ressort précité
Jusqu'à ce que le protecteur touche le fond du logement.
The base screwable into the heated mass, and in the axis of the housing, allows the aforementioned spring to slide freely
Until the protector touches the bottom of the housing.

L'épingle passe entre deux spires du ressort de compression du capteur et assure l'immobilisation du capteur dans son logement. The pin passes between two turns of the compression spring of the sensor and ensures the immobilization of the sensor in its housing.

Sur les dessins annexés, on a représenté schématiquement et à titre d'exemple, un mode de réalisation de l'invention. In the accompanying drawings, there is shown schematically and by way of example, an embodiment of the invention.

La figure 7 représente l'élévation avec coupe partielle d'un capteur en position dans une masse chauffée. FIG. 7 represents the elevation with partial section of a sensor in position in a heated mass.

La figure 2 est une vue de dessus qui montre l'immobilisation du capteur dans son embase et l'action à exercer afin de l'extraire de cette position. Figure 2 is a top view which shows the immobilization of the sensor in its base and the action to be taken in order to extract it from this position.

La figure 3 montre une embase à serrage à six pans. Figure 3 shows a hexagon clamping base.

La figure 4 montre une embase à serrage par tourne vis
On voit sur les dessins que le capteur de température suivant l'invention comprend un protecteur 1 qui enferme l'élément de mesure
a) soudure chaude d'un thermocouple soudée à l'extrémité du protecteur.
Figure 4 shows a screw-clamp base
It can be seen from the drawings that the temperature sensor according to the invention comprises a protector 1 which encloses the measuring element
a) hot welding of a thermocouple welded to the end of the protector.

b) ou soudure chaude d'un thermocouple isolée de la masse du protecteur.  b) or hot welding of a thermocouple isolated from the mass of the protector.

c) ou résistance valable platine ou cuivre ou nickel. c) or valid resistance platinum or copper or nickel.

d) ou tout autre élément de mesure présent ou futur pouvant prendre place dans cette configuration. d) or any other present or future measurement element that can take place in this configuration.

Le protecteur est maintenu en pression mécanique par le ressort 2 dans le fond du logement 5. Cet ensemble cou- lisse librement dans l'alésage de l'embase 3 filetée en 4 vissée dans Z masse chauffée 6. L'embase 3 peut avoir deux configurations selon quril est plus commode de recourir à un serrage au moyen d'une clef qui enfourche le polygone 7, ou un serrage par tournevis inséré dans la fente 13 de la figure 4. A la partie supérieure de l'embase la fente 8 accueille le ressort 9 d'immobilisation du capteur fixé au corps de l'embase et enroulé autour de lui.La figure 2 montre le mode opératoire qui permet d'extraire le capteur de son logement en exerçant une pression 14 sur le ressort 9 afin que l'épingle dégage l'aire cylindrique intérieure 22 usinée dans l'embase permettant ainsi à nouveau de faire coulisser librement le capteur dans l'embase. Une tresse métallique 10 protège les conducteurs reliés à l'élément de mesure placé dans le protecteur 1. Sous la tresse métallique un guipage 11 ou autre revetement isole les conducteurs 12. The protector is maintained under mechanical pressure by the spring 2 in the bottom of the housing 5. This assembly slides freely in the bore of the base 3 threaded at 4 screwed into Z heated mass 6. The base 3 can have two configurations according to quril is more convenient to resort to a tightening by means of a key which straddles the polygon 7, or a tightening by screwdriver inserted in the slot 13 of figure 4. At the upper part of the base the slot 8 accommodates the sensor immobilization spring 9 fixed to the body of the base and wound around it. FIG. 2 shows the operating mode which makes it possible to extract the sensor from its housing by exerting pressure 14 on the spring 9 so that the pin releases the internal cylindrical area 22 machined in the base thus again allowing the sensor to slide freely in the base. A metal braid 10 protects the conductors connected to the measuring element placed in the protector 1. Under the metal braid a covering 11 or other covering insulates the conductors 12.

La nature maléable de l'ensemble constitué par les conducteurs 12, la tresse 10, l'isolant 11 et le ressort 2, permet de le courber s'il y a lieu, sous un angle quelconque à la sortie de l'embase 3, ce qui est avantageux et meme indispensable dans certains cas. The malleable nature of the assembly formed by the conductors 12, the braid 10, the insulation 11 and the spring 2, makes it possible to bend it if necessary, at any angle at the outlet of the base 3, which is advantageous and even essential in certain cases.

La mise en place et le démontage du capteur est commode et rapide et ne nécessite pas d'outil lors d'un changement de capteur, l'embase restant solidaire de la masse chauffée.  The installation and disassembly of the sensor is convenient and quick and does not require a tool when changing the sensor, the base remaining integral with the heated mass.
