Digital pgauge ressure gauge
Analog pressure gauges have a long history of providing reliable pressure readings. But the popularity of digital pressure gauges is growing.
A brief overview of pressure gauges
Simply put, a pressure gauge is a tool that provides the simplest, most direct way to measure and display gas and liquid pressure. It is a common equipment in refineries, industrial plants and power plants that has a wide range of applications in healthcare, energy production and many other industries around the world.
Analog pressure gauges were first developed more than 150 years ago when steam processes became common in factories during the Industrial Revolution. It is difficult to understand in today’s world where technology is changing rapidly. But since then, the basic mechanics of making analog gauges have remained relatively unchanged until around the 1970s and 1980s. As the world shifted to the digital age, the production of the first digital pressure gauge began.
Since 2000, with the introduction of new production techniques and technologies, and more advanced construction in construction, significant progress has been made in both. And although analog gauges are thought to exist for a long time, digital pressure gauges now have many advantages over analog pressure gauges. This article addresses the fundamental differences between the two and the myriad advantages of digital over analog pressure gauges.
Comparison of digital pressure gauge with analog pressure gauge
While both analog and digital sphygmomanometers have the same function, they use very different technologies and perform well in a variety of applications, and there are several distinct features of digital sphygmomanometers that really set them apart from technology. The analog standard highlights the industrial age.
Analog pressure gauge
Analog pressure gauges, sometimes known as pressure gauges. They have a hand that responds directly to changes by referring to numbers on the scale related to the pressure felt by the measuring element. Moving the hand means changing the pressure, which is easily visible and controllable.
Advantages: Cheap analog pressure gauges are cheap and easy to use, and because they are made of mechanical parts, they do not need a power supply.
Disadvantages : Analog pressure gauges are completely mechanical. They are made of small gears and moving parts, so they are very likely to be damaged under normal conditions in the program or laboratory. As a result, analog pressure gauges are particularly prone to mechanical vibration, and in constant pressure applications, moving parts on analog gauges can wear out quickly, leading to misreadings and potentially unsafe working conditions. They are exposed to excessive pressure, extreme temperatures, corrosion, clogging, vibration and steam, so they need constant re-calibration. Analog calibration requires the removal and manipulation of adjusting screws, which can lead to user error.
Digital pressure gauge
Digital pressure gauges use pressure transducers to display pressure readings on a digital indicator. They provide fast results and clear readability based on the settings that the user enters before the measurement. Digital gauges operate with confidence and provide continuous readings and are usually powered by a battery, ring or solar power.
Advantages : There are several main features that make digital gauges superior to their analog counterparts.
- Durability – Digital pressure gauge can operate without damage in extreme temperatures, hazardous conditions and areas under heavy mechanical vibration. They are made to withstand abuse and cracking. They are typically made of aluminum or stainless steel with thick, crack-resistant plastic faces to protect them from impact, drops, flying debris and chemicals. Dangerous to protect. As a result, they are more resistant to vibration and excessive pressure than analog sensors.
- Calibration – Calibrated digital pressure gauge is much more reliable than calibrated pressure gauge with analog output. Digital calibration is done using software, so it is more accurate.
- Customization Options – Digital pressure gauge can be customized to fit your application – You can add and remove features and modify engineering units. Some digital gauges have the ability to create custom units that allow pressure to be displayed in torque or power units or, if required, custom applications. This is almost impossible for analog gauges – the whole screen has to be changed to change the unit. Many digital gauges also automatically record minimum and maximum readings, so this important information can be accessed quickly – (usually with the push of a button). Analog gauges require pointers that are a bit troublesome and inaccurate to adjust. And a big digital advantage in data collection. Digital hydraulic pressure gauges include outputs for sending results to a computer, data logger, or other tool for data or analysis.
- Readability – Large screen digital pressure gauges are easy to read. Most of them also have a bright backlight. Reading from an analog gauge always requires interpreting the location of the hand. In some applications, where readings have to be performed remotely, or when the pressure is measured several times at the same time, the probability of error increases.
Disadvantages : Keep in mind that digital pressure gauges always need a power supply, so if your application requires very rare use of pressure gauges, it may not be an ideal option. Batteries do not last forever, especially when they are on the shelf for months. Digital pressure gauges also require special certifications, which are mandatory in some industries (usually when used in hazardous locations) and best practices in others. Analog pressure gauges do not require certification.
There will be no discussion of comparing analog and digital pressure gauges at full cost. They are more expensive because digital gauges use advanced microprocessors and equipment. However, analog gauges often fail – they are not very reliable and need to be regularly calibrated and replaced, so what you initially save on price may cost you more in the long run.
