What should you know about pressure gauges to use in your business?

Pressure gauges are fluid intensity measurement devices required for setting up and tuning fluid power instruments. These pressure tools are indispensable in troubleshooting many potential accidents to the pressure systems. Without measuring pressure gauges, reading the fluid power systems has been unreliable since there would be no way to know whether there are any pressure leaks and changes in the system. Every hydraulic pressure system functions within a standard pressure measurement to perform accurately. However, if the pressure changes, it affects the operating system of the instrument. Pressure gauge has been in application for hundreds of years, and its applications have been evolved tremendously. With innovative techniques, scientists have developed many kinds of pressure gauges, such as low-pressure gauges, tridicator, high-precision test gauges, duplex pressure gauges, etc., so it’s now possible to measure many pressures correctly. The pressure gauge methods can be hydrostatic or mechanical. Pressure gauges can measure three different types of pressure:

Absolute pressure gauge

The absolute pressure measurement refers to the kind of pressure existing in  full vacuum, and its measured value is zero; that’s why it’s called absolute pressure. A barometer can be the best example of a hydrostatic pressure gauge used for measuring absolute pressure. Moreover, the absolute pressure gauge is applied in measuring vapor pressure, checking leakage in tanks and circuits, and various meteorological applications.

Gauge pressure measuring devices

Gauge pressure devices are used for measuring standard atmospheric pressure at sea level. If the atmospheric pressure is more than the gauge pressure, the measurement is positive and vice versa. Bourdon tube pressure gauge is the most commonly used device for measuring gauge pressure. From all hydrostatic gauges, the u-tube manometer is considered the most effective one. The gauge pressure devices are widely used in industrial applications such as power, petrochemical, refrigeration, refineries, air-conditioning, and sanitation industries.

Differential pressure gauges

Differential pressure refers to the difference between two pressure points. This pressure gauge method is a particularly produce mechanical value. Ideal examples of differential pressure gauge devices are Piston-style, Diaphragm type, Bellows, etc. This pressure gauge is generally applied in refineries, chemical plants, etc.

What are the different types of pressure gauges?

Low-pressure gauges

As the name suggests, a low-pressure gauge is used for measuring the gaseous and liquid pressure so the pressure would not obstruct its functioning. This pressure gauge is specifically required in plant construction processes, clean rooms, and pneumatic systems.

Tridicator

Tridicator is recognized as a combination of pressure and temperature gauge. This pressure gauge device works for producing a combined value of a single-point pressure gauge and thermometer. Additionally, tridicator can be easily installed, which can reduce time and save your expenses. In this device, pressure can be read in both psi and kPa; similarly, the temperature can be measured in Fahrenheit and Celsius.

Liquid filled gauges

Liquid filled gauge is used for hydrostatic applications, where the fluid fill dampens the pressure system’s pulsation effectively. Rather than using a dry gauge, a liquid-filled gauge can give readings that are more accurate.

There are many other pressure gauges available in the market, so you have to make a good decision with your choice. Consider factors like the devices’ level of accuracy, appropriate dial size for readability, mounting option, durable materials for the various environment, etc. Choose a manufacturer who can give you a wide variety of gauge options, so you can choose the right device without any issue.
