Explanation: The dial face on a pressure gauge is the part of the gauge that displays the pressure measurement in a clear and easy-to-read format. It typically includes a series of markings, such as numbers or graduations, that correspond to different pressure values. The dial face may also include other features, such as color-coding or warning zones, to help users quickly identify pressure conditions.
