What Do You Need to Know About the Different Types of Industrial Pressure Gauge?

Industrial pressure gauges are critical for measuring and monitoring pressure in industrial processes and equipment. Choosing the right type of pressure gauge for your needs can be daunting, given the wide variety of available options. After all, you could be monitoring pressure in either a high-pressure or low-pressure environment or may need to measure the differences between two entirely separate points. So with so much on the line, how do you go about picking the best pressure gauge for your application?

Bourdon Tube Gauges

Bourdon tube gauges are the most commonly used type of pressure gauge. They consist of a curved tube that is fixed at one end and free to move at the other end. When pressure is applied to the tube, it straightens out, which is then converted into a reading on the gauge. Bourdon tube gauges are suitable for low to medium-pressure applications and are available in various materials, including brass and stainless steel.

Diaphragm Gauges

Diaphragm gauges are suitable for measuring low-pressure and vacuum applications. They consist of a flexible metal or elastomeric diaphragm that is deformed by pressure, which then moves an indicating needle. Diaphragm gauges are ideal for use in corrosive environments since they are available with chemically resistant diaphragms.

Differential Pressure Gauges

This type of gauge measures the pressure difference between two points in a system. They consist of two Bourdon tubes that are connected to a differential pressure element. Differential pressure gauges are widely used in HVAC, process control and flow measurement applications.

Digital Pressure Gauges

Digital pressure gauges offer high accuracy and resolution and are easy to read. They have LCD displays instead of traditional dials and are available in a range of pressure scales, making them suitable for various applications. Digital pressure gauges are ideal for use in automation and industrial control systems.

Vacuum Gauges

Vacuum gauges are used to measure pressure below atmospheric pressure. They are available in various types, including bourdon tubes and diaphragms. Vacuum gauges are widely used in scientific and high-tech applications, including medical research, semiconductor manufacturing and space exploration.

Your Takeaway

Knowing the different types of industrial pressure gauges and their unique features can help you select the best pressure gauge for your needs. Whether you are monitoring pressure in a low-pressure or high-pressure environment or need to measure the pressure difference between two points, a pressure gauge can meet your needs.
