Patent ID: 8381572

Claim:
A device for acquiring measurement data for determining gases in liquid, which has a housing for use in water, an inner chamber of the housing, and a flat membrane that is supported by the housing and bounds part of the inner chamber of the housing, and in which at least one sensor for measuring gases in liquids is installed within the inner chamber of the housing, wherein the sensor includes a thermocatalytic element ( 8 ) for decomposing at least one gaseous hydrocarbon in the inner chamber ( 2 ) of the housing and where the inner chamber ( 2 ) of the housing is designed in a way that supports gas circulation, wherein a temperature stabilizer is arranged in the housing, the sensor being constructed so that decomposition of a hydrocarbon by the thermocatalytic element takes place in the inner chamber with improved measurement dynamics and reduced lag time, wherein the membrane is gas-permeable in both directions and has a backside mounted on a gas-permeable carrier so that the carrier mechanically reinforces the membrane so as to permit use of the membrane at depths of up to 6,000 meters, wherein a pump for generating continuous gas circulation is arranged in the inner chamber of the housing so that the gas circulation of measurement air is continuous between the membrane and the at least one sensor to provide a continuous equilibration of the same measurement air/medium and reduce reaction time.
