Abstract

L'invention a pour objet un dispositif d'évaluation de la charge en microorganisme d'un fluide d'usinage, comportant :- deux électrodes (7, 9), destinées à être immergées dans le fluide d'usinage (3), comportant : * une anode (7), dont une portion au moins de la surface est recouverte d'un film bioabsorbant (11), * une cathode (9),- un générateur (G), générant du courant entre les deux électrodes (7, 9),- une unité de mesure (M), évaluant au moins une grandeur électrique (I(t)) variant avec la présence et l'épaisseur d'un film de microorganismes se formant sur le film bioabsorbant (11), - une unité de contrôle (UC), connectée au générateur (G) et à l'unité de mesure, configurée pour déduire des mesures une évaluation de la charge en microorganismes du fluide d'usinage (3).
