Abstract
A dual gauge system determines pressures of two separately contained gases by use of two separate pointer—Bourdon tube sections within the dual gauge. The Bourdon tube of a first one of the sections is gaseously coupled to a first one of the contained gases to determine pressure of the first one of the contained gases and a Bourdon tube of a second one of the sections is gaseously coupled to a second one of the contained gases to determine pressure of the second one of the contained gases. Accuracy of pressure determination is enhanced by allowing for separate calibration of each of the two gauge sections.
