ABSTRACT:
A pressure sensor comprising an air-tight container, enclosing water vapor therein, which elastically deforms depending upon a variation in the external pressure to result in a variation in the content volume thereof, a moisture sensor disposed within the container, and a moisture detector which electrically detects a variation in the amount of moisture to be absorbed by the moisture sensor depending upon the internal partial pressure of the water in the container due to the elastic deformation of the container.
