Pressure transmitters are used in industrial and process applications to measure the pressure of liquids, fluids, and gases in different working equipment. These transmitters are a vital component in process industries, especially the oil & gas industry which deals with a variety of fluids and gases.

Types of Pressure Transmitters

Pressure transmitters can be categorized into four main types:

1. Gauge Pressure Transmitter

As the name suggests they measure the gauge pressure with respect to the atmospheric pressure. These types of transmitters are widely used in process industries as they involve the use of liquid and gases. The need to keep their pressure under check makes gauge pressure transmitter a vital component of the industry.

2.  Absolute Transmitters

These transmitters are used to measure pressure with respect to full vacuum. Basically, the media under measurement is placed in a sealed chamber to create a reference to absolute vacuum. These absolute pressure transmitters are generally employed in areas which demand a very high level of accuracy.

3. Differential-Pressure Transmitter

These transmitters are generally used to compare different types of pressure. Their applicability extends to both, the level applications and the flow applications. These transmitters have been used to measure flow rates owing to their advantages over other alternatives.

4. Multivariable Pressure Transmitters

These transmitters are used in cases where more than one variable is involved. These variables can be temperature and volumetric flow amongst other variables. These types of transmitters are widely used in industries involving the measurement of gas and steam flow.

Accuracy of Pressure transmitters

The accuracy of pressure transmitters has substantially increased over time. Accuracy consists different parameters of the device including linearity, hysteresis, and repeatability. These are three of the most important features of any pressure transmitter irrespective of the type of instrumentation and application it is used for. Many times, the manufacturers club all these parameters and represent it as a single value.
