The PX70 Series is a piezoresistive pressure sensor, suitable for PC board mounting; it comes in a TO-5 package. The PX70 is available in full scale ranges from 0.3 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 measurements 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.
