  • Device for continuous temperature measurement of dew point of flue gases
    Patent number: 3930398
    Abstract: A device for continuous temperature measurement of the dew point of flue gases, in which the signal of the sensitive unit, carrying information on the appearance of a condensate film on the condensation surface of the dew point temperature transmitter, is applied simultaneously to the regulator of the heating element and the regulator of the cooling element. Both of these are included in the condensation surface temperature control unit, wherein temperature control of the condensation surface is attained by the heating and cooling means operating simultaneously. The transmitter is provided with heating and cooling means.
