CAPTEUR A FILAMENT EN COUCHE MINCE AUTOPORTE, SON PROCEDE DE FABRICATION ET SES APPLICATIONS DANS LA DETECTION DE GAZ ET EN CHROMATOGRAPHIE GAZEUSE

摘要

Detector of the filament type for determining a static or dynamic characteristic of an ambient medium, comprising a resistive component intended to be heated by the Joule effect in said medium, and an interface region suitable for reacting with this medium by a physico-chemical process with an effect, depending on the characteristic to be determined, on an electrical characteristic of this interface region, in which there is a supporting blade through which there is at least one aperture and at least one filament including this resistive component, consisting of one or more thin film(s) and comprising a central portion located in the aperture and end portions via which this central portion is connected to the supporting blade.
