Web1. If the gauge in the image reads 5 psi at the orange mark and the atmospheric pressure is 14.7 psi, which of the following are the gauge and absolute pressures? A – gauge = -5 psi, absolute = 9.7 psi. B – gauge = 5 psi, absolute = 9.7 psi. C – gauge = -5 psi, absolute = 19.7 psi. D – gauge = 5 psi, absolute = 19.7 psi WebA gauge with a vacuum range measures negative pressure only. And then some gauges measure only positive pressure. Typically, these include atmospheric pressure at zero on the dial, often called gauge pressure. However, at times there are requirements for gauges that use absolute zero as the pressure point. These are referred to as absolute gauges.
