Halbleiter-Gassensoren / Metalloxid-Gassensoren

Gassensoren (MOX) ist abhängig von der Bauform des Sensors. Sensoren auf Si-Bulk-Substraten benötigen eine Leistung von ca. 1 Watt (bei 400 °C). Mikromechanische Aufbauten, sogenannte »Microhotplates«, sorgen für eine thermische Entkopplung des Sensors vom Gehäuse und reduzieren so den Leistungsverbrauch deutlich. Von Fraunhofer IPM konzipierte Sensoren wei-sen gassensitive …

Gesundheit: Beurteilung nach dem TVOC-Konzept

· Beurteilung nach dem. TVOC. -Konzept. Bewertungen von leicht flüchtigen Fremdstoffen im Innenraum stehen grundsätzlich vor dem Problem, dass ein komplexes, zeitlich und räumlich oft sehr variables Gemisch beurteilt werden muss. Zu vielen Stoffen liegen zudem nur unzureichend toxikologische, insbesondere am Menschen gewonnene, Daten vor.

uRADMonitor » Metal Oxide VOC Sensors

A Metal Oxide Sensor (MOX) is one of the sensors widely used for monitoring VOCs in the air. It consists of a porous layer heated by a filament that undergoes a redox reaction when it comes in contact with a VOC, changing the electrical resistance across the circuit in proportion to the concentration of the VOC. This transduction principle gives high sensitivity for monitoring air quality, and ...
