If you need to install pressure gauges on your machines or equipment, then you have to choose between analog or digital devices. Before you make a decision, take time to understand the differences between the two and their pros and cons.

Read on to learn more.

How Do Analog Pressure Gauges Work?

Analog pressure gauges are mechanical devices. You take a reading from the device by looking at the position of a needle on a dial. These dials are big and clear enough to read from a distance so you don't have to get close to the gauge to see it.

These gauges are typically cheaper than digital models because they have a simpler design and manufacturing model. They also run without a power supply.

So, they work well in remote or hard-to-access areas or in places where you don't have a safe power source. For example, they are safe to use in hazardous working areas where you can't use an electrical supply.

However, analog gauges have downsides. Their mechanical parts are prone to damage if the gauge is subject to excessive vibration or movement. You will have to recalibrate a gauge periodically as it will lose its accuracy over time.

While these gauges are easy to read, people can easily misread their levels if they don't look at a dial from the right angle. If you look at an analog dial from the wrong angle, then the reading you see won't be accurate.

How Do Digital Pressure Gauges Work?

Digital pressure gauges use digital technology to display readings, so they need a power source. Instead of looking at a needle position, you look at a numbered display to take a reading.

These displays are easy to read; they often have backlights so that you can take a reading in any lighting condition. The display gives a set number that remains the same from any viewing angle.

These gauges also have some quality advantages. They are more robust and can withstand more environmental stress. Most models typically need far less recalibration than analog alternatives.

You can also order custom pressure gauges to exactly fit an application if an off-the-shelf product doesn't completely suit your needs. Some devices also have data log monitoring features so that you can create a digital copy of results as you take them.

However, you will pay a higher price for a digital pressure gauge. You also need a suitable power source for each device. If your power goes out or the gauge runs out of battery power, then it won't work.
