OMEGA’s PX26 Series pressure sensors feature state-of-the-art silicon technology which permits both sides of the diaphragm to handle liquids. A unique conductive seal between the silicon diaphragm and the plastic housing allows for wet/wet applications and lower production costs than typical gold wire silicon sensors. This new construction has a larger diaphragm than traditional silicon sensors, resulting in increased long-term stability.

Sometimes OK but sometime notWe bought this a month ago for our water pressure loop test, initally it was good and be sensitive to pressure drop changes and read correctly.
However, after switching and squeeze air out of in and outlet lines, found the connection was easy to break and get wet so readings were really out of range.
