Definitions

  • dew point hygrometers in which the air is cooled until the water vapor condenses.
  • the dew point temperature determined in this way corresponds to the saturation temperature of the air, from which the relative humidity can also be derived if the sensitive temperature of the air flow is known.
  • DE-OS 37 13 864 discloses an apparatus and a method for determining the dew point of components of a gas mixture, from which the invention is based in the preamble of claim 1.
  • the known device has a moisture sensor, which can be both a dew point mirror and a cooled electrode arrangement.
  • a condensate collector is provided which can be cooled or heated by means of a Peltier element.
  • At least the moisture sensor and the condensate collector in a measuring chamber.
  • a further increase in the significance can be achieved in that the flow of the measurement gas is stopped at least during the heating phase. At the same time, this also reduces the amount of sample gas required to determine the dew point.
  • a compact construction also results if one side of a heat exchanger, in particular an evaporative heat exchanger, is designed as a condensate collector.
  • the condensate collector can be heated, for example, by means of a resistance heater or by means of microwave radiation.
  • the use of a sintered metal heat exchanger as a condensate collector is particularly useful in the event that the dew point of several components is to be determined in succession in a gas mixture. In this case, the component with the highest dew point must first be completely removed from the sample gas volume. Only when this has happened can the next lower dew point of a component be determined. That is, the condensate collector also works as a refrigeration dryer.
