Digital pressure gauges measure the pressure within a system in a special manner. They convert the pressure to an electronic signal. The gauge shows the pressure using a digital display, furthermore the signal can be used to control equipment. Digital gauges in comparison with analog ones have a higher accuracy. Read our article on analog pressure gauges if you want to learn more about that type.
Why choose a digital over an analogue pressure gauge?
Next to a higher level of measurement accuracy digital pressure gauges offer options that are not available for analogue ones. A few examples of possible options are:
- Backlighting: If pressure readouts are needed in dark conditions this options proves to be a great solution. Backlighting ensures that you are able to read the display in every lighting condition.
- Min/Max values: This option provides better analysis of the set pressure in a system.
- Bargraph display: The bargraph display shows the trend of the measured pressure. You can for example easily see if the pressure has an increasing, decreasing or steady trend.
- Battery powered: This ensures that the pressure can be read in case of power outage.
- Rotatability: Most digital pressure gauges allow for the display unit to be rotated to a large degree (e.g. 300°)
