The PX70 Series is a piezoresistive pressure sensor, 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 four standard package options. The PX71 for gage and absolute ranges, is available without fittings while the PX72 has a top mounted 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 uni- or bidirectional measurement.
