Abstract:
1. A gauge for indicating a pressure of a fluid, comprising: a face having a first plurality of graduation marks for indicating a pressure, where said first plurality is calibrated to measure pressure that is ascending; said face having a second plurality of graduation marks for indicating a pressure, where said second plurality is calibrated to measure pressure that is descending; said gauge including a sensor magnet for detecting the pressure of the fluid; a pointer magnet coupled to a pointer and in communication with said sensor magnet for moving said pointer in correspondence with a movement of said sensor magnet; and wherein said pointer traverses across both said first and second pluralities of graduation marks for indicating the pressure of the fluid in either an ascending direction or descending direction; and wherein said first plurality of graduation marks represent a first scale and said second plurality of graduation marks represent a second scale that is different from said first scale.
