An absolute pressure transmitter measures pressure relative to a perfect vacuum (zero reference). The displayed value in Bara is always positive, and atmospheric pressure variations have no effect. This type is used in applications where pressure changes must be independent of environmental pressure variations.
✅ Example: If atmospheric pressure is 1 bar and the tank pressure is 5 bar, the displayed value will be 5 bar.
