Abstract
A device includes: a chip, which includes a oscillatable cantilever with a first piezoelectric transducer for exciting cantilever oscillation, wherein the first cantilever extends into a cavity of the chip; a cantilever temperature sensor in an end section of the cantilever; a second temperature sensor spaced from the cantilever; a heating element located in the free end section of the cantilever and separated from the second temperature sensor by at least one cavity section; and an evaluation unit for determining density and viscosity as well as thermal conductivity and specific heat capacity of a gas mixture based respectively on oscillation characteristics of the cantilever and measured values of gas temperature from the cantilever temperature sensor, the second temperature sensor and a power consumption of the heating element.
