- La figure 1 représente une vue schématique d'un équipement selon l'invention.- Figure 1 shows a schematic view of equipment according to the invention.
L'équipement selon l'invention concerne le domaine de l'analyse de liquide polyphasique. Il s'applique de manière non exclusive mais préférentielle, au fluide/huile de coupe et huile minérale.The equipment according to the invention relates to the field of multiphase liquid analysis.

un sous-ensemble hydraulique constitué de pompes péristaltiques, électrovannes, et de réservoirs remplissant les fonctions de stockage de fluide, avec le fluide à analyser d'une part, la solution tampon pour l'étalonnage, la solution de conservation (ionique pour la protection d'électrode de pHmètre) d'autre part.a hydraulic sub-assembly consisting of peristaltic pumps, solenoid valves, and reservoirs fulfilling the functions of fluid storage, with the fluid to be analyzed on the one hand, the buffer solution for calibration, the preservation solution (ionic for protection on the other hand.
un sous-ensemble électronique : avec des systèmes d'instrumentations (capteurs et sondes ), d'un ensemble de microcontrôleurs en charge de la collecte, le traitement et la transmission de données issues de capteurs mais aussi l'ordonnancement des tâches des composantes hydrauliques.an electronic sub-assembly: with instrumentation systems (sensors and probes), a set of microcontrollers in charge of collecting, processing and transmitting data from sensors but also scheduling the tasks of the hydraulic components .
L'équipement prélève périodiquement un échantillon de fluide de travail depuis un réservoir ( 1 ) grâce à une pompe péristaltique (2) et un conduit (3).The equipment periodically takes a sample of working fluid from a reservoir (1) using a peristaltic pump (2) and a conduit (3).
Le liquide prélevé est transféré dans une enceinte de mesure (4) équipée d'un capteur de température (5), d'une électrode d'un pH-mètre (6), d'un capteur infra-rouge (7), d'une photodiode ultraviolet (8) et d'une source d'éclairage (9).The sampled liquid is transferred to a measuring chamber (4) equipped with a temperature sensor (5), an electrode with a pH meter (6), an infrared sensor (7), d 'an ultraviolet photodiode (8) and a light source (9).

Le circuit électronique (10) commande la séquence de fonctionnement des pompes péristaltiques (3, 12, 14).The electronic circuit (10) controls the operating sequence of the peristaltic pumps (3, 12, 14).
L'équipement décrit permet de résoudre plusieurs problèmes:The equipment described solves several problems:
Il permet des collecter, traiter, et analyser l'ensemble des mesures permettant de caractériser l'état et la qualité de l'huile à un moment précis. L'ensemble des mesures collectées permet de suivre l'état d'une huile de coupe.It makes it possible to collect, process, and analyze all of the measurements making it possible to characterize the condition and quality of the oil at a specific time. All of the measurements collected make it possible to monitor the state of a cutting oil.
L'intérêt de l'équipement selon l'invention est de permettre de mesurer non seulement les propriétés du liquide sur tous les modes de fonctionnement de la machine associée (machinesoutils, ou machine électrique) mais surtout de suivre l'état des mesures résiduelles et non résiduelles à un instant donné et donc de prévoir l'évolution de l'état de l'huile de façon précise et fiable.The advantage of the equipment according to the invention is that it makes it possible to measure not only the properties of the liquid on all the operating modes of the associated machine (machine tools, or electric machine) but above all to monitor the state of the residual measurements and non-residual at a given time and therefore to predict the evolution of the state of the oil in a precise and reliable manner.
Dans les solutions connues, les fluides sont envoyés périodiquement en laboratoire pour être soumis à des tests de colorimétrie, réfractométrie, spectrométrie. Elles ne prévoient pas la mesure sur site de la température, au même moment que les autres mesures. Or la température n'étant pas un paramètre résiduel, certains autres attributs du fluide sont modifiés. Par exemple, la température d'une huile minérale est corrélée à sa teneur en eau, et cette propriété n'étant pas résiduelle, lors des analyses en laboratoire, ou a posteriori, la comparaison est difficile voire impossible et l'évolution de l'état de l'huile difficile à prévoir.In known solutions, the fluids are sent periodically to the laboratory to be subjected to colorimetry, refractometry, spectrometry tests. They do not provide for on-site temperature measurement at the same time as the other measurements. However, since temperature is not a residual parameter, certain other attributes of the fluid are modified. For example, the temperature of a mineral oil is correlated with its water content, and this property not being residual, during laboratory analyzes, or a posteriori, comparison is difficult or even impossible and the evolution of the oil condition difficult to predict.
Dans le cas du liquide de coupe, idéalement, les mesures qualitatives ne sont complètement fiables que pendant leur usage lors d'un usinage par exemple, car il conserve intacte l'ensemble des propriétés permettant de juger de la nonqualité du fluide. A postériori, ces propriétés sont altérées et donc moins fiables et moins parlant dans le cadre d'une analyse prévisionnelle de la dégradation.In the case of the cutting liquid, ideally, the qualitative measurements are completely reliable only during their use during a machining for example, because it keeps intact all the properties making it possible to judge the nonquality of the fluid. A posteriori, these properties are altered and therefore less reliable and less meaningful in the context of a predictive analysis of degradation.
Une autre spécificité est la possibilité de procéder à plusieurs types de mesures de haute précision, grâce à un seul dispositif. Sur le Ph et la concentration, la précision du dispositif est de + ou -0,01 d'écart tolérable.Another specificity is the possibility of carrying out several types of high precision measurements, thanks to a single device. On Ph and concentration, the accuracy of the device is + or -0.01 of a tolerable difference.
Cette faculté unique est rendue possible grâce à la mise en place de plusieurs techniques, par exemple:This unique ability is made possible by the implementation of several techniques, for example:
L'étalonnage automatique des pH-mètres, grâce à une solution tampon : normalement dans le temps, un pH-mètre perd son calibrage de base et devient de facto moins précis. Cela est également valable pour des mesures de conductivité par exemple. Cette technique n'est donc pas exclusive.Automatic calibration of pH meters, thanks to a buffer solution: normally over time, a pH meter loses its basic calibration and becomes de facto less precise. This also applies to conductivity measurements, for example. This technique is therefore not exclusive.
Le calibrage automatique des spectromètres grâce aux modèles analytiques rendant ainsi possible l'usage du même dispositif sur plusieurs types de fluide pour en identifier la concentration.Automatic calibration of spectrometers using analytical models thus making it possible to use the same device on several types of fluid to identify its concentration.
