Mount Design

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 new
construction has a larger diaphragm
than traditional silicon sensors, resulting
in increased long-term stability.
