What are the Pressure Gauges?

Gauges are instruments which assist is measuring the dynamics of various materials. They are popular in industrial environment as they assist in stating the accurate performance of pressure, temperature, velocity and like factors within a device which can hamper the output sometimes.

Pressure gauges are most widely used in industries hence are also known as industrial gauges. They are mostly used in applications to measure pressure, temperature and sometimes to scale the flow of gases or liquids. Generally they are available in various kinds ranges, dimensions and sometimes even made to order to suit a specific demand and match specific requirements.

They are usually made of metals which are non-corrosive in nature as they are constantly subjected to various gases, liquids, water and steam. The pipe fittings and accessories in gauges are commonly made of alloys like brass. If gauges are made using general metals which corrode, easily then the fittings and accessories are made of stainless steel.

There are various types of pressure gauges available, some of the most commonly used types are listed below, with detailed explanation of their uses, similarities, disparities.

Air: These devices are used to handle and measure applications which deal with high pressure liquids and gases. The vessel used to hold air in these devices is usually a tire. The performance of an application is maintained largely by these devices to control accuracy always. So always ensure that optimum air is filled within the tire as too less can flatten the tire and excess air can explode the tire.

Oil: Generally oil is used to lubricate engines of industrial machines. This helps in smooth functioning of the motor and other parts of the machine without causing any friction or corrosion. These devices help in maintaining the level of oil in engines.

Differential: They measure vacuum pressure for various applications. The parts in differential gauges have elongated tubes, within which it is easy to trace fluctuating pressure. Mostly they are popular to trace pressure in liquids and gases. They have two access, ports which are linked to trace differences.Pressure is calculated in a range within these devices allowing to easily track any inconsistencies.

Digital: Used extensively in industrial environments as they ensure accuracy always. They also translate pressure into numerical values for easy understanding. Mostly digital gauges are popular in automobile manufacturing, pharmaceutical and food processing industries. They also help in filtering impurities if any prevalent.

Diaphragm: A membrane or casing expands or contracts accordingly to enable the differential pressure. The diaphragm gauges are made of containers which are separated by a membrane or diaphragm and linked to the supply of pressure. The deflection of the diaphragm states the level and position of the pressure.
