Claims (8)

1. Machine à laver industrielle comportant un tambour rotatif (1) qui comprend un dispositif pour le réglage de la concentration du produit consistant en une cellule (20) capable dé mesurer un paramètre physique qui dépend de la concentration, un dispositif pour doser le produit dans la machine à laver et une unité de réglage électronique qui contrôle ladite cellule de mesure et contrôle le fonctionnement du dispositif de dosage en fonction de celle-ci, caractérisée en ce que la cellule de mesure (20) est disposée à l'intérieur du tambour (1) et est capable de tourner avec lui.
2. Machine à laver selon la revendication 1, dans laquelle l'unité de réglage est telle que le dispositif de dosage du produit est coupé pendant la position émergée de la cellule (20).
3. Machine à laver selon la revendication 1 ou 2, dans lequelle la cellule (20) convient pour mesurer la conductivité.
4. Machine à laver selon la revendication 3, dans laquelle le dispositif doseur est coupé quand la valeur du paramètre contrôlé tombe au dessous d'une valeur préalablement réglée.
5. Machine à laver selon l'une quelconque des revendications précédentes, qui est une machine à laver à tunnel à tambour unique.
6. Machine à laver à tunnel selon la revendication 5, dans laquelle la cellule de mesure (20) est électriquement connectée à l'unité de réglage au moyen d'un contact coulissant entre la partie rotative et la partie statique de la machine.
7. Machine à laver à tunnel selon la revendication 5 ou 6, dans laquelle l'unité de réglage corrige la valeur du paramètre détectée en utilisant une valeur de référence qu'on mesure pendant que la cellule (20) est en position émergée.
8. Machine à laver à tunnel selon la revendication 7, dans laquelle l'unité de réglage corrige la valeur des paramètres physiques en utilisant la valeur de référence mesurée au cours du cycle précédent de rotation.
