In simple words, a pressure gauge is an equipment used to measure the pressure from a gas or a liquid. Used in several refineries, electrical, and industrial plants, these tools offer the most direct and easiest way to measure liquid and gas pressure. For 150 years, analog pressure gauges were used, but that changed around the 1970s with the introduction of the digital age. Since then, new technologies and solutions have been introduced to streamline the pressure measuring process. The new digital method offers far more advantages than its analog counterpart, and this is the reason why industries need to use digital ones for measurements.

Why is A Digital Pressure Gauge Better Than Analog One?

Pressure transducers are used by the digital pressure gauges to display the pressure readings on the digital indicator. The digital solution offers clear readability and fast results, which is based on the settings the user inputs before taking the measurements. The digital pressure gauges are primarily powered by solar power or batteries. This solution offers consistent reading and is more reliable than analog pressure gauges. Several characteristics make digital gauges better, and some of them include:

• Durability
  One of the best features of digital ones is they can perform seamlessly in extreme temperatures, in areas with heavy vibrations, and even hazardous conditions without failure. A digital pressure gauge is designed to withstand cracking and even abuse. Typically built from strong materials like stainless steel or aluminum makes them more durable than analog ones. These pressure gauges also have a face made from crack-resistant plastic, which further protects them from flying debris, shock, and hazardous chemicals.
• Customization Options
  You can customize your digital pressure gauges according to your specific requirements by either adding or removing some features in the engineering unit. Certain digital gauges can even create customized units, which will allow the pressure to be displayed in force or torque units. Doing the same thing with an analog pressure gauge is nearly impossible. Several digital ones also record the high and low reading automatically; this makes referencing them in critical situations much simpler. Also, data collection is one of the most notable advantages of digital pressure gauges. The hydraulic ones can send the collected data to a computer, data logger, or any other specified instrument for better analysis.
• Calibration
  Keeping an analog pressure gauge calibrated is a massive task. However, once you have calibrated the digital pressure gauge, it will remain calibrated much more reliably. Also, in digital ones, the calibration is done using software, hence it will be much more accurate and precise.
• Readability
  The digital pressure gauge always features a large and easy-to-read display. These displays are often supported by a bright backlight, and taking a reading from these digital gauges is easy. However, reading from analog ones requires interpreting the location of the needle. Misreading due to parallax error is frequent with analog gauges, depending on the angle of the person who is converting the data, the dial can appear to be in several different directions. This can increase the chances of mistakes, and the accuracy of data can be compromised as well. Since the digital pressure gauges display a numerical value of pressure, there will be no parallax error.
