Unlike relative humidity, dew point measurement is independent of temperature. However, when measuring dew point, pressure conditions must be taken into account. Beware of Temperature Differences When mounting a humidity probe into a process, avoid temperature drops along the probe body.
Dew point is the temperature to which air must be cooled for water vapor in it to condense into dew or frost. At any temperature there is a maximum amount of water vapor that the air can hold.This maximum amount is called water vapor saturation pressure. Addition of more water vapor results in condensation.ir compression increases water vapor pressure and thus dew point. It is important to take this into consideration if you are bleeding the air to atmosphere before taking a measurement. The dew point at the measurement point will be different from the dew point in the process.
