What is dew point temperature? What is frost point? When should I choose dew point as the parameter I measure? What are the pros and cons of measuring dew point versus relative humidity? Does dew point change as the ambient temperature changes?

The frequency versus temperature response was used for the dew point detection. Preliminary results confirm the great SAW sensitivity to dew deposition. Moreover, because of the thermal sensitivity, the accuracy of the relative humidity measurement may be considerably improved....
humidity. However, the non-linear form of the capacitance-temperature transfer function around the dew point, and the fact that the exchange time constant for water evaporation and condensation is strongly dependent on the vapour pressure at the dew point presents complexities in devising a control...
humidity (amount of water molecules in the measured gas) in terms of relative humidity (RH) while the temperature sensor measures the temperature of the polymer sensor. From these two values, the microprocessor in the transmitter electronics calculates the dew point temperature. Like the capacitive ...
