    摘要： A device for measuring dew point or humidity comprises a single resonator and at least one temperature-regulating element arranged to control the temperature of the resonator by heating and/or cooling. Frequency measuring circuitry is arranged to generate signals indicative of measured frequencies of the resonator. At least one controller or processor receives the signals and determines the temperature of the resonator at which condensation (e.g., dew, frost, or condensed vapor) appears on the resonator or evaporates from the resonator according to the signals.

    摘要： An optical fiber is provided with a first measurement portion and a second measurement portion. The first measurement portion is provided with a heater and a hygroscopic layer made of a resin in which a material having a deliquescent property is dispersed. Meanwhile, the second measurement portion is provided with the heater and a non-hygroscopic layer having a lower moisture absorption capacity than the capacity of the hygroscopic layer. The heater is brought into heat generation by being supplied with electric power, and temperatures at the second measurement portion and temperatures at the first measurement portion are measured with a temperature measurement device. Then, an analyzer calculates a humidity based on an integrated value of differences between the temperatures at the first measurement portion and the temperatures at the second measurement portion.

    摘要： A sensor device is provided for detecting thawing on surfaces with interdigital electrodes formed in a resistance layer which is formed on a substrate. In order to develop the sensor device further so that the measuring speed of the sensor device is further increased, the disclosure proposes that the interdigital electrodes and recesses between the interdigital electrodes have a moisture-sensitive hydrophilic surface through condensation cores applied to it.
