A pressure gauge is an essential component in industrial machinery. It measures the pressure of gas or liquid in a particular environment. Modern pressure gauges are simple and easy to use. However, keep in mind that there are various types of gauges for different industrial applications.

Absolute Pressure Gauges

Absolute pressure is referred to pressure that exists in a vacuum. The gauge used to measure pressure in a complete vacuum has a measuring cell kept apart by a diaphragm. You’ll also find the reference chamber in the instrument. A hydrostatic gauge, such as a barometers, can be used to calculate absolute pressure.

These types of gauges are used in a variety of applications. People looking to measure the vapor pressure of liquids and vacuum reactors can use absolute pressure gauges. Furthermore, if you want to check leakages in a tank and circuits, these gauges are a good option. You’ll find absolute pressure gauges used mainly in vacuum pumps and the food packaging industry.

Gauge Pressure Measuring Devices

Gauge pressure is closely linked to the standard atmospheric pressure at sea level. Gauge pressure is positive if it is more than the standard level and negative when less than the atmospheric pressure. A Bourdon tube pressure gauge is commonly used to measure gauge pressure. It has a C-Shaped tube and is sealed at one end. Diaphragms and bellows are also used to measure these pressures.

They are one of the most popular gauges used in industrial applications. You’ll find them in different industries, such as chemical, petrochemical, power, pharmaceuticals, air-conditioning, and much more.

Differential Pressure Gauges

Differential pressure gauges don’t give any readings about the levels of pressure at two different points. It only outlines the difference between the two readings. You can use piston-style, Diaphragm, and Bellows gauge for different applications. These gauges are used in unique industrial applications, such as monitoring filtration. You’ll find these gauges in petrochemical plants and chemical factories for the most part.

Other Types of Gauges

You will find commercial gauges used in HVAC systems and refrigeration plants. Manufacturing industries and OEMs use industrial pressure gauges for a variety of purposes. Furthermore, you’ll find process pressure gauges being used in industries with extreme conditions. These gauges can withstand intense vibrations, corrosions, and harsh environments, which is why they’re used in the petrochemical industry.

High precision gauges are common in testing labs and the pharmaceutical industry, where accurate calibration and readings are required. Like process pressure gauges, you’ll also see duplex pressure gauges used in harsh environments to measure the difference between two applied pressures.

It can be quite difficult to choose the right gauge for your application. You’d need to consider the levels of accuracy, readability, durability, and a lot more in your gauge purchasing decision.
