A device for determining the partial pressure or the concentration of a steam in a volume, includes a sensor body that can be oscillated. The temperature of the sensor body can be controlled to a temperature below the condensation temperature of the steam, and the oscillation frequency of the sensor body is influenced by a mass accumulation of the condensed steam on a surface of the sensor body. Means are provided for generating a gas flow from the sensor surface in the direction of the volume through a steam transport channel that adjoins a window to the volume. In order to increase the maximum service life of the sensor body, the means for generating a gas flow has a slit nozzle designed as an annular channel. 12. A device for determining a partial pressure or a concentration of a vapor in a volume () , the device comprising:{'b': 5', '6', '5', '20', '3', '2', '6, 'a sensor body () configured to be brought into oscillation, the sensor body having a temperature that is controllable to a temperature below the condensation temperature of the vapor, and an oscillation frequency that is influenced by an accumulated mass formed by the vapor condensing on a sensor surface () of the sensor body (), wherein vapor transport channel () adjoins a window () to the volume (), through which the vapor diffuses in a direction of transport (T) towards the sensor surface (); and'}{'b': 16', '6', '20, 'an annular channel () that forms a wide slit nozzle through which a gas flow is generated, the gas flow flowing from the sensor surface () towards the vapor transport channel () in a direction counter to the direction of transport (T) of the diffusion of the vapor.'}2165. The device of claim 1 , wherein the annular channel () is provided in an immediate vicinity of the sensor body ().32. A device for determining a partial pressure or a concentration of a vapor in a volume () claim 1 , the device comprising:{'b': 5', '5', '6', '5, 'a sensor body () that is configured to be brought into ...
