How to read a Pressure Gauge


Knowing how to read a pressure gauge and what the readings mean are critical to the safe operations of pneumatic systems. No matter what industry you operate in, if you use pneumatics you need to be able to make readings and react to changes in pressure to ensure the safety of employees and maintain your rate of production. If there is a problem in your pneumatic system, everything stops. Here we are going to clear up some misconceptions about pressure gauges, discuss how to read a pneumatic pressure gauge, and what they tell you about the performance of your system.

What is gauge pressure?

Gauge pressure is a measurement of the pressure in a pneumatic system relative to the ambient pressure of the atmosphere. Unlike absolute pressure, which measures pressure relative to a perfect vacuum, gauge pressure indicates how much pressure is in a system compared to the air around us. This measurement is particularly important in pneumatic systems where precise pressure readings are essential for safe and effective operation. Some pressure gauges have bands on the dial to alert users to dangerous levels of pressure that must be addressed by either relieving the pressure using a valve or adding extra pressure to the system to continue operation.

How to read a pressure gauge

Reading a pressure gauge is straightforward once you understand the basic principles. A typical pneumatic pressure gauge features a dial displaying units of pressure (usually in pounds per square inch, or PSI). The needle on the dial points to the current pressure level within the system. It is important to read the gauge in the context of the system’s normal operating range to determine if the pressure is at an acceptable level. The dial may have certain pressures highlighted to help operators identify pressure levels quickly. Each system will have its own safe levels of operation, and it is up to the operator to ensure the system is kept within these safe boundaries.

The benefits of a reliable gauge

Over pressure or under pressure can bring work to a halt, and pose a safety risk to workers. Reliable pressure gauges are important for both safety and production. These small but important parts of your pneumatic system are a window that lets you look inside and assess performance without stopping it. The reliability of your pressure gauge has a huge impact on the reliability and safety of your operations. Without one, operators are guessing pressure and endangering themselves and the rate of production. Reliable pressure gauges offer three main benefits to your business:

  • Accuracy – Precise measurements are key to the safe and continuous operation of pneumatic systems. Without accuracy, a pressure gauge is useless. Our reliable gauges are manufactured to the highest standards and help you to ensure your systems are predictable and reliable.
  • Durability – The environments where pneumatic systems are used are often industrial settings that demand durability from each component. A reliable pressure gauge needs to be highly durable to withstand the rigours of industrial environments and provide accurate readings every time.
  • Safety – The primary concern of any operator of a pneumatic system should be safety. The pressures these systems contain can be dangerous and pose a consistent hazard to workers. Reliable pressure gauges help operators predict and prevent anomalies in the system and prevent accidents in the workplace.

The importance of checking your gauge regularly

Regular checks of your pressure gauge are essential for maintaining system integrity. Without regular checks, the gauge is useless. A faulty or inaccurate gauge can lead to operational inefficiencies, safety hazards, and increased wear and tear on the pneumatic system. Routine inspections help in the early detection of potential problems and allow operators to make sure that the pneumatic system is operating within safe and optimal parameters. This can reduce downtime, wear and tear, and workplace accidents. Regular checks should be scheduled multiple times a day and routine maintenance inspections should happen regularly.
