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.
