# Analog and digital, the pros and cons of the two most popular pressure gauges

In this article, we are going to go over the pros and cons of two pressure gauges, analog pressure gauges, and digital pressure gauges. We will also touch on how conversion charts help with pressure gauges as well. If you’re trying to decide which gauge to purchase, we hope our pro and con tips help you make a clearer decision when it comes time to pick a pressure gauge for your needs.

## What are pressure gauges?

Pressure gauges are pressure measuring instruments that can measure pressure in a variety of different units. They come in two main types, analog pressure gauges, and digital pressure gauges. Analog pressure gauges use a needle to show the pressure level on an easy-to-read dial, while digital pressure gauges use electronic sensors with LCD displays or LED screens to display the pressure reading.

Pressure is measured using Pascal (Pa) or pounds per square inch (psi). One pound per square inch equals 145 kilopascals (kPa), so 1 psi = 14.5 kPa, and one kilopascal equals 100 pascals (Pa). For a gauge to be accurate, it must be calibrated before use. The pressure gauge should be calibrated to the pressure source it will be measuring pressure from. A pressure conversion chart is a handy tool to have when using pressure gauges. This chart converts pressure measurements from one unit of measurement to another, making it easier to read the pressure gauge regardless of what unit of pressure it is displaying.

For example, if you are using a digital pressure gauge that displays readings in pounds per square inch (psi), but needs to convert the reading to kilopascals (kPa), you can use the pressure conversion chart to do so. The chart will tell you that 1 psi = 14.5 kPa, so by multiplying the psi reading on your gauge by 14.5, you can convert it to kPa. Having a pressure conversion chart available makes calibrating and using your pressure gauge much easier. Now that we know what pressure gauges are and how to convert pressure readings from one unit of measurement to another, let’s take a look at the pros and cons of analog pressure gauges and digital pressure gauges.

### The analog pressure gauge

The analog pressure gauge has been a popular pressure gauge for many years. It is a pressure gauge that uses a needle and a dial to measure pressure. The pros of the analog pressure gauge include: The needle is easy to read, especially when compared to digital pressure gauges. It doesn’t require batteries or power to work. It can also be used in a variety of environments and doesn’t produce a lot of noise. And the cons of the analog pressure gauge include: It can be difficult to see the needle in bright light or sunlight, and it’s not as accurate as digital pressure gauges.

### The digital pressure gauge

Digital pressure gauges are more accurate than analog pressure gauges and they are easier to read. The pros of digital pressure gauges include: They are more accurate than analog pressure gauges. They are easy to read, even in bright light or sunlight. They can be used in a variety of environments. And the cons of digital pressure gauges include: They can be more expensive, so if you’re looking for a cheaper gauge this may not be the right choice for you. They also require batteries or power to work, which may be a small downside for some.

In this article, we have gone over the pros and cons of analog pressure gauges and digital pressure gauges. We hope we’ve helped you decide which pressure gauge is right for your needs with the help of the information above, and hope you learned how the different pressure gauges work and how they perform. It’s important to learn the correct information before purchasing a pressure gauge because there are different features some may have that others do not!
