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.
