Wet/Dry describes a differential pressure measurement device which is compatible with a liquid on the positive pressure side and a dry/non-condensing gas on the negative pressure side.
This is most commonly found with compact designs where a gauge reference design has been adapted to measure differential pressure. The negative side of these pressure transducers were only designed to withstand exposure to atmospheric air pressure and contain composite materials, and in some cases exposed electronics and connecting wires.
