Measuring -1 to 1 psi (-0.069 to 0.069 bar) differential pressure, this pressure sensor provides a 10 mV/V ratiometric output at ±1% accuracy. It suits pressure-drop measurement and board-mount integration.

OMEGA's PX26 Series pressure sensors feature state-of-the-art silicon technology that 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 construction has a larger diaphragm than traditional silicon sensors, resulting in increased long-term stability.
