The PX70 Series piezoresistive 
pressure sensors are packaged in  
a TO-5 case suitable for PC board 
mounting. The PX70 is available in 
full scale ranges from 0.3 to 100 psi 
as well as 4 standard package 
options. The PX71, for gage and 
absolute ranges, is available without 
fittings, while the PX72 has a topmounted tube fitting (bottom is  
vent for gage). The PX73 is also 
available in gage ranges and has  
a bottom tube fitting (top is vent).  
For differential measurements, the 
PX74 has top and bottom tubes and 
can be used for unidirectional or 
bidirectional measurement.
