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.
Featured differential pressure measurement products
DPT200 High One Side Overload Differential Pressure Sensor - DP transmitter for measuring pressure difference between two pressure points which can tolerate up a very high overload pressure independently on either the positive or negative side port or both together at the same time.
DPS300 User Switchable Pressure Range, Volts or Current Output Low DP Sensor - The DPS 300 is a low range HVAC differential pressure sensor. The lowest possible pressure range is 0...100 pascals. 2 or 3 switchable pressure ranges, plus volts or current output are included with most standard configurations.
