    摘要: The invention relates to a device and to a method for the implementation thereof for measuring the dew point temperature of a gaseous element, alone or in a mixture, which can have a low calorific capacity and/or an aggressive chemical character like sulfur, circulating for example in a pipe, working at a range of temperatures varying from around 100 to 400°C and providing an optimized precision in the measure due to an optimized signal-to-noise ratio. For this purpose, the device includes in particular a calorimetric unit (2), two thermometric means (3, 4) and a measuring surface (8), each of the latter (3, 4, 8) being in direct thermal contact with the calorimetric unit and the gaseous element. Each thermometric means is capable of generating a signal representative of the thermal effect associated with the condensation and/or the evaporation of the gaseous element on said surface (8).

    摘要: A device for measuring the condensation temperature of a gas at a measurement point is disclosed, in a process chamber (6) essentially enclosed by a wall (4) with a heat extraction device for removal of heat from the process chamber (6) such that the gas temperature is reduced to the dew point and which comprises a temperature sensor (16). The invention is characterized in that the heat extraction device comprises a heat tube (10) which may be positioned with a first section (10a) in the process chamber (6) and a second section (10b) outside the process chamber (6) and the temperature sensor (16) is provided for measurement of the temperature in the heat tube (10).

    摘要: The invention relates to a sensor arrangement (100) for detecting dew on surfaces using interdigital electrodes (14) which are formed in a resistance layer (13) that is formed on a carrier material (10). In order to develop the sensor arrangement (100) in such a manner that the measuring speed of the sensor arrangement (100) is increased further, the invention proposes that the interdigital electrodes (14) and depressions (16) between the interdigital electrodes (14) have a moisture-sensitive hydrophilic surface (18) by virtue of applied condensation nuclei.

    摘要: The invention concerns dew point hygrometers based on condensation of dew on ends of optical fibers, or on surfaces of an optical prism. The invention also concerns a dew sensor for determining the natural dew condensation by optical means and a dew sensor capable of detecting dew by detecting a change in capacitance.

    摘要: The invention provides for a dynamic dew point analysis method as well as an apparatus for carrying out the method wherein the method comprises: arranging a moisture containing gas in the immediate vicinity of at least two thermocouples, where one thermocouple is shielded from the gas, creating an analogous temperature change in both thermocouples and registering the temperature in both thermocouples during a cycle where the condensation point of the moisture containing gas is passed, using the different temperatures from the at least two thermocouples as input for determining the dew point according to basic thermodynamic principles.
