Pressure Gauges

A pressure gauge is a fluid intensity measurement device. Pressure gauges are required for the set-up and tuning of fluid power machines, and are indispensable in troubleshooting them. Without pressure gauges, fluid power systems would be both unpredictable and unreliable. Gauges help to ensure there are no leaks or pressure changes that could affect the operating condition of the hydraulic system.

Pressure gauges come in a wide variety of designs, each of which serve specific applications and industries. It is important to get familiarised with the factors affecting selection of the right gauge for your system.

According to EN 837-2, for safety purposes, a pressure gauge shall be selected with a range such that the maximum working pressure does not exceed 75% of the maximum scale value for steady pressure or 65% of the maximum scale value for cyclic pressure.

When using hazardous pressure media such as oxygen, acetylene, combustible substances and toxic substances, it is necessary to choose a pressure gauge with additional safety measures such as a blow-out device on the rear. These safety measures ensure that any leaks or bursting of pressurised components will not injure anyone at the front of the scale.
