Full-scale ranges from 0.3 to 100 psi are available, as well as four standard package options: no fitting, top fitting, bottom fitting, and differential. For gage and absolute ranges, the PX71 can be ordered without fittings and the PX72 has a topmounted tube fitting (bottom is vented). The PX73 has a bottom tube fitting (top is vented). For differential measurements, the PX74, with top and bottom tubes, can be used for unidirectional or bidirectional results.
