ABSTRACT:
A pressure gauge for a pressurized device is disclosed that provides a simple, efficient and highly visual indication of pressure change from a normal condition to various abnormal conditions. The pressure gauge includes a chamber, a pressure converter located within or operably associated with the chamber, a rotary member coupled to the converter and having an indicator pattern and a cap including at least one window through which at least a portion of the indicator pattern is viewable. Once the gauge is brought into fluid communication with a pressurized device, then the cap may be rotated or adjusted to align the windows with a desired marker type placing the gauge in a normal or first indicator data. A change in pressure in the chamber will cause the gauge to undergo a change to a new or different indicator state.
