Abstract
A continuous vapor sensor is assembled within a partially open protective enclosure which restricts (but does not exclude) the entry of liquid and means for excluding liquid from a portion of the enclosure, such as a non-wetting attachment material. The assembly allows the use of a continuous sensor which is adversely impacted by liquid contact in locations where the assembly may be immersed. The enclosure traps a sufficient amount of vapor to maintain a minimum vapor volume when the enclosure is submerged to a significant depth below a water level. The means for excluding controls the location of the minimum vapor volume to protect the sensor.
