What are pressure transmitters?

Pressure transmitters refer to the special devices designed to measure the pressure of fluids, liquids, and gases in industrial equipment and process control applications. Also called pressure transducers, these transmitters are widely used to build a liquid interface detector that is capable of measuring, monitoring, and maintaining the pressure level of different liquids and gases across connected pipelines. This is why pressure transmitters are primarily preferred in the oil and gas industry. 

By enabling easy monitoring of pressure levels, pressure transmitters help in ensuring the smooth functioning of many industrial systems, thereby preventing any potential disasters caused by any variations in the prescribed pressure levels. Not only that but they are also built to withstand harsh environments, making pressure transmitters ideal for industrial use.

Types of pressure transmitters

Pressure transmitters are generally available in four types. These are: 

Gauge Pressure Transmitter

This type of pressure transmitter is used to measure the gauge pressure of liquids and gases and is used extensively in process industries. 

Absolute Transmitter

These can measure pressure in respect to full vacuum and have higher accuracy.

Differential-Pressure Transmitter

This type of pressure transmitter usually compares various types of pressure. 

Multivariable Pressure Transmitter

These are used where measuring pressure with more than one variable is required. The variables may include volumetric flow and temperature, among other things.

Importance of pressure transmitters

Pressure transmitters are used extensively across the industrial sectors not only to measure pressure but also to identify leakages. They are growing in popularity across many sectors from research and development to manufacturing. As such, pressure transmitters form an important part of industrial process control systems.
