Pressure is one of the most common measurement processes in commercial and industrial spaces, second to only temperature. Industries use several types of pressure measuring devices, including transmitters, sensors, and transducers. However, pressure gauges are widely used as a simple way to measure and display the data.

Different Types of Pressure

When dealing with pressure, it’s important to understand what types of pressure exist, keeping different reference points of measurement. The three pressure references are:

  • Gauge Pressure: This type of pressure references atmospheric pressure.
  • Absolute Pressure: This type of pressure references to vacuum pressure. The sum of gauge pressure and atmospheric pressure equals absolute pressure.
  • Differential Pressure: This type of pressure gauge measures the difference between the type of different pressures.   

What to Consider Before Buying a Pressure Gauge

When out in the market to find a pressure gauge for a particular application, it’s essential to know the differences between different pressure gauges and then make an informed decision. Two types of pressure gauges are available: analog gauges and digital gauges. Each gauge works with different technology and is designed for different conditions.

Analog Gauge

Analog gauges use a sensor to measure the pressure and display the data by pointing the needle to a particular number on the scale. Generally, analog gauges are known for their high accuracy. Additionally, they have a lower cost and require little maintenance. Analog gauges follow the principles of either Bourdon Tube or Bellows

Digital Gauges

Digital gauges, on the other hand, provide extremely accurate readings using modern microprocessors and sensors. They use digital displays to show the readings. Even though they cost significantly higher, they’re a popular choice amongst industrial and commercial spaces.

Due to advanced technology, digital gauges are used to provide quick and accurate results, especially in uses where small changes are expected, which are difficult to read on analog gauges. Since there are only a few moving parts involved, they are known for their reliability. Additionally, they’re simpler to use and offer the flexibility of adapting to different pressure units, as the operator requires. Moreover, results from digital gauges are easily transferrable to a computer for analysis and storage.

Most digital gauges work with either strain gauge sensors or piezoelectric sensors.

Applications of Pressure Gauges

As mentioned earlier, pressure gauges are available to cater to different commercial and industrial needs. From huge factories to households, pressure gauges are used everywhere, including heating systems, tire pressure monitors, boilers, and others.

Commercially, they’re used in several different industries, including medical, automotive, food and beverage, energy, and manufacturing.
