A pressure transmitter is an instrument used to measure and report the pressure of a fluid. Pressure transmitters can be used to measure fluid pressure in areas as small as fuel lines and as large as the Earth’s atmosphere. Air pressure sensors, for example, can be used to precisely measure barometric pressure in an area. Pressure transmitters are also known as pressure sensors; they differ in name only.

Applications of Pressure Transmitters
Pressure transmitters have become vital tools in all kinds of industrial contexts. They are essential in helping to ensure the safe and effective operation of industrial equipment. Engines require pressure transmitters to ensure adequate oil pressure levels. Waterjet cutting professionals require water jet pressure monitoring equipment to maintain the highest level of effectiveness of their equipment.
Pressure transmitters are also important parts of many kinds of heavy equipment. Hydraulic systems, if over or under-pressurized, can become ineffective or even dangerous. Pressure transmitters indicate when such equipment is operating at peak performance, as well as when it requires maintenance. Pressure transmitters are used in weather instruments, aircraft, automobiles, and other kinds of vehicles. They also often monitor engines in many different kinds of machinery.
Pressure Transmitter Design and Customization
Pressure transmitters distinguish themselves from each other in several ways. The most immediately apparent way in which a pressure transmitter distinguishes itself is in terms of its physical appearance. An automobile oil pressure transmitter, for example, will be visible to casual observers only as an indicator on a dashboard. Pressure transmitters can be configured as dials, gauges, screens, and in many other ways.
The most complicated pressure transmitter displays are part of computer display systems. Such systems are usually coupled with control equipment. For example, if an advanced pressure transmitter were to transmit an irregular reading to its display computer, in addition to displaying that information, it may be connected to a system that automatically addresses the problem. These systems support the safe functioning of many waste water treatment facilities, power plants, and some kinds of machinery.
The other main way in which pressure transmitters distinguish themselves from each other is in terms of their measurements relative to atmospheric pressure. Pressure transmitters that measure pressure relative to atmospheric pressure are called gauge sensors, while models that measure pressure relative to an atmospheric pressure of 0 PSI are referred to as absolute sensors. Each variety is chosen based on the unique conditions of its application.
