Title (EN) PORTABLE FLUID SCREENING DEVICE AND METHOD
(FR) PROCEDE ET DISPOSITIF PORTABLE SERVANT A ANALYSER UN FLUIDE
Abstract:
(EN) This invention relates to a fluid screening device (10), comprising: an impedance sensor (22) including a cavity for holding a fluid to be screened, an impedance of the impedance sensor being affected by conditions of the fluid; an impedance measuring circuit (38) for measuring the impedance of the impedance sensor with respect to at least one frequency; a processsor (34) for processsing impendance data taken by the impedance measuring circuit (38) for purposes of determining a condition of the fluid; and a connector (25) which operatively couples the impedance sensor (22) to the impedance measuring circuit (38); the connector (25) allowing the impedance sensor (22) to be selectively detached from the impedance measuring circuit (38).
(FR) L'invention concerne un dispositif servant à analyser un fluide et composé d'un capteur d'impédance comprenant une cavité servant à contenir le fluide à analyser, l'impédance de ce capteur d'impédance étant sensible aux états de ce fluide; d'un circuit de mesure d'impédance servant à mesurer l'impédance du capteur d'impédance par rapport à au moins une fréquence; d'un processeur servant à traiter des données d'impédance relevées par le circuit de mesure d'impédance dans le but de déterminer un état de ce fluide; d'un connecteur couplant le capteur d'impédance au circuit de mesure d'impédance et permettant au capteur d'impédance d'être détaché de façon sélective du circuit de mesure d'impédance.
