General Description
OMEGA’s PX70 Series is a piezoresistive pressure sensor in a TO-5 package
suitable for PC board mounting. These devices are available in full scale ranges
from 0.03 to 100 PSI as well as several standard package options. For gage and
absolute ranges, the PX71 is available without fittings, while the PX72 has a top-
mounted tube fitting (bottom vent for gage). The PX73 is also available in gage
ranges and has a bottom tube fitting (top vent). For differential measurement,
the PX74 has top and bottom tubes and can be used for uni-directional or bi-
directional measurement. All models are operated from a constant current
excitation supply. The PS-KIT-1 provides the necessary components to convert
a constant voltage (9-30 Vdc) to a 1 mA constant current source.
