The different types of gas pressure gauges include:
Bourdon Tube Pressure Gauge
This type of pressure gauge is the most common pressure gauge used. It is mechanical; thus, it can measure pressure without an electric power supply. Steel is the material used for its construction to aid in resistance to corrosion and wear for heavy vibration applications and dynamic pressure load.
Diaphragm Pressure Gauge
This type of pressure gauge is designed for measuring low-pressure intensities. A diaphragm pressure gauge is also called a membrane pressure gauge. The working principle of this instrument is based on the deflection of a flexible thin membrane called the diaphragm. The bourdon tube pressure gauge can measure pressure from 0.6 – 7000 bar. Therefore, it is compatible with low and high-pressure applications. In addition, it has a compact structure that is suitable. The indication of the pressure is made using a needle. A pinion arrangement with the diaphragm is used to help the movement of the needle.
Capsule Pressure Gauge
This pressure gauge consists of two corrugated diaphragms welded together at their periphery to form a capsule. In sensing the pressure, this capsule is the main element that senses the pressure. One of the diaphragms consists of a hole in the center for allowing the medium to enter. When pressure is applied, the diaphragms expand or contract. This type of pressure gauge is utilized to calculate the pressure of gasses and substances with up to 600 mbar.
Absolute Pressure Gauges
These pressure gauges are used for measuring the pressure independent of the natural fluctuations in atmospheric pressure. To the side of the measuring element, a reference measure vacuum is fixed and is not subject to pressure; thus, its pressure is zero without any variation. Absolute pressure gauges are most commonly utilized in scientific laboratories. They are not affected by altitude, so they are also utilized in aeronautics, ventilation, heating, and air conditioning systems.
Differential Pressure Gauge
This pressure gauge measures the difference in pressure between two chambers separated by an element moving to and from according to the pressure changes. The media chamber is separated from the vacuum chamber by a diaphragm present This type of pressure gauge is utilized for measuring the difference in pressure between two chambers that are separated by an element moving to and from according to the pressure changes. A diaphragm in the differential pressure gauge separates the media chamber from the vacuum chamber. When there is an increase in pressure, deformation of the diaphragm into the vacuum chamber occurs. This deformation and change are then converted to produce a pressure value.
Bellows Pressure Gauge
Devices that measure absolute and differential pressure are called bellows pressure gauges. The gauge's key component, the bellows, is a flexible membrane whose expansion and contraction help quantify the system's pressure difference. The force transfer to the transmission mechanism depends on the bellows' diameter. Therefore, a bigger diameter is chosen to have enough surface area for the pressure to act upon when measurements of very low pressures are required.
This type of pressure gauge is utilized in the measuring of low-pressure applications. Thin-walled flexible metal-connected tubes are used for making the bellows in the devices. The tubes form a shape like an accordion, and they are sealed in the gauge's free end.
Manometer Pressure Gauge
This device is used for measuring the pressure on a fluid by the principle of balancing one column of fluid against the second column. In the manometer tube, one end is connected to the place where pressure is measured, and the other end will be open to the atmosphere.
