Pressure gauges are mechanics used widely across manufacturing, chemical processing, HVAC, and water treatment corporations. Their purpose is to provide a pressure-sensitive reading of a gas or liquid in an industrial setting. Pressure gauges play a significant operational role as many industrial systems rely on the precision of their readings.

Without pressure gauges, fluid powered machines would face unpredictable failures. By implementing one into your machinery, you can monitor pressure around the clock, with any cause for concern flagged immediately, avoiding dangerous or costly errors.

This blog will discuss the workings of a pressure gauge and the importance of their role in an industrial setting, namely their functionality and safety.

How does a pressure gauge measure pressure?

Inside a pressure gauge is a pressure-sensitive mechanism that’s measured internally with the results displayed via a dial or digital readout. The pressure sensitivity is measured as the mechanism deforms under the pressure of the gas or liquid, this is then converted into a reading through measurement, to be displayed to the user. The concept of a pressure gauge is built upon the principle of Hooke’s Law, which states that the amount of force applied to a spring is equal to the returned force of resistance the spring gives back, i.e. if you pull on a spring, it will pull back with equal force.

When considering this law with a pressure gauge in mind, a pressure gauge is measuring the pressure of said media (a liquid or gas), when the pressure fluctuates, the mechanism changes and the change in pressure can be read on the dial or digital readout of the pressure gauge.

This principle applies to all pressure gauges, the full range can be explored at the GNWShop.

How do mechanical and digital pressure gauges differ in functionality?

Mechanical pressure gauges are often referred to as analogue gauges. The function of this type of pressure gauge is based around the mechanical movement of a bourdon tube, or in some designs a diaphragm seal, which in turn drives a needle around a dial. A digital pressure gauge differs by using a diaphragm and strain gauge as opposed to a bourdon tube or diaphragm seal. The digital displays allow the pressure gauge to display and record readings with more ease.

Whilst mechanical pressure gauges can be more affordable compared to digital gauges, and don’t rely on a power supply, digital pressure gauges remain calibrated for far longer, the importance of which can be read about here. They also perform well in areas of extreme vibration, pulsation, and corrosion and display a clear reading, with some models having the option of a backlight.

What role does pressure play in efficiency and safety?

Pressure gauges are implemented in industrial settings to act as a constant monitor to pressure sensitive systems. By having constant access to precise pressure readings, the role of the pressure gauge works to prevent hazardous conditions. By recording any changes in pressure, problems can be dealt with rapidly to avoid any potential issues before they escalate. Further to this, pressure gauges are incredibly user friendly mechanisms, meaning room for error is near to non-existent, allowing for universally readable results.

Not only do pressure gauges play an important role in maintaining a safe industrial setting, but one that works efficiently too. The monitoring of pressure levels means that systems can operate at their optimum, this serves organisations as they’re able to keep any energy wastage to a minimum and regulate performance standards, keeping them maintainable. More about the importance of keeping a safe measure on pressure systems and the role calibration plays can be found here.

How does the type of pressure gauge impact its function and application?

A library of pressure gauges exists due to the variation in requirements from different industries. An example of the comparison between mechanical and digital pressure gauges mentioned earlier in the blog is that digital gauges often provide higher accuracy and work best in a lab setting, however mechanical gauges are sufficient for general industrial use. It’s important to consider the environment your pressure gauge is going to be operating in, as well as the media pressure being measured.

Each pressure gauge is designed with a specific pressure range in mind, for example bourdon tube gauges are suitable for medium to high pressure, whilst diaphragm gauges are ideal for low pressure applications. To ensure you’re getting the most accurate reading and your pressure gauge is running at the highest efficiency, it’s crucial that you select the right gauge for the level of pressure being measured.

When it comes to application, there are specific features to bear in mind. For industries that require a sanitary environment, diaphragm seal pressure gauges are ideal for systems dealing with food, pharmaceuticals, or chemicals. For more hazardous environments, intrinsically safe digital gauges are the best approach.
