Absolute pressure transmitters can measure the pressure of atmospheric air, other gases, vapors and liquids from the zero reference point, i.e. absolute vacuum. It is important to understand that any pressure transmitter takes measurements against reference pressure. Absolute pressure transmitters, for one, have absolute zero as that reference. There are also pressure transmitters that measure pressure against atmospheric pressure (gauge pressure transmitters), transmitters that measure vacuum pressure against atmospheric pressure (vacuum transmitters), transmitters that register two opposing pressures (differential pressure transmitters).
The absolute pressure transmitter is built around a sensor. One side of the sensor is exposed to vacuum created when it was made. The other side receives pressure from gas or liquid. The output signal from the sensor goes to the electronic unit that calculates the absolute pressure. There are analog and digital pressure transmitters. A digital pressure transmitter features a converter that converts analog signal into a digital one.
