METHOD AND DEVICE FOR MEASURING DEW POINT TEMPERATURE Russian patent published in 2023 - IPC G01N25/68 G01K13/24 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a method and device for measuring the dew point temperature of moist gases, in particular to determining the humidity of gaseous media from the dew point temperature, and can be used in all areas of application where there is a need for measurements of this kind. A device is proposed for measuring the dew point temperature of a wet gas, containing a housing with a hole in the lower part and an opening in the upper part, a tubular refrigerator in the form of a spiral from a pipe mounted in the housing, with at least 4 temperature sensors installed in the pipe in the gas flow, connected to a microprocessor device, wherein the input end of the pipe is located inside the housing of the technological device, a vacuum pump connected to the output of the tubular refrigerator, and the microprocessor device has an electrical output signal driver.

EFFECT: device is capable of determining the dew point temperature in the range from +45°C to +95°C, which corresponds to a moisture content of 65 to 3000 g of water per 1 kg of dry air.
