Absolute pressure transmitters
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.
Absolute pressure transmitters allow measuring pressure of gases, liquids, including their aggressive varieties. Absolute pressure transmitters find their use in production environments where technological process parameters depend on the absolute pressure value. Absolute pressure transmitters are used in chemical, food industries, processing, oil and gas industries, laboratory research, pharmaceuticals production.
DMP 331 universal general purpose pressure transmitter is the most popular absolute pressure transmitter. Our customers also favor DMP 333, high pressure absolute pressure transmitters, DMP 331P, pressure transmitter featuring a wide range of food-grade unions, and a number of other pressure transmitters switches.
