Wet/Dry

Wet/Dry in the context of pressure measurement refers to the medium in contact with the pressure sensing element. A wet system implies the pressure sensor is directly exposed to the process fluid, while a dry system involves a separating barrier between the sensor and the fluid. Additionally, a wet/dry configuration specifically describes a differential pressure measurement device compatible with a liquid on the positive pressure side and a dry/non-condensing gas on the negative pressure side. This distinction is crucial as it impacts sensor selection, accuracy, and maintenance requirements.
