What Is a Pressure Gauge and Their Use?

Pressure gauges are a common measurement instrument utilized by various machinery and vehicles alike, allowing for fluid intensity to be determined with ease. Pressure gauges ensure that fluid power systems remain reliable and predictable, allowing operators to monitor conditions for leaks, pressure changes, or other issues that may deter performance or safety. In this blog, we will discuss pressure gauges in more detail, allowing you to better understand their use and capabilities.

For a standard hydraulic system, pressures must be kept within a certain range for optimal operations and safety. This is why pressure gauges are extremely important, as they ensure that operators are always aware of when values exceed or fall below the required pressure range. Hydraulic pressure gauges are generally implemented at or near the pressure port of a pump, allowing it to receive an indication of system pressure. Nevertheless, hydraulic pressure gauges can be situated anywhere pressure needs to be watched, such as areas where pressure values need to be different than the pump pressure.

While pressure gauges have been in use across industries for more than a century already, they still continue to be advanced with new capabilities to increase their performance and accuracy. As hydraulic systems have become increasingly popular for standard power applications, modern devices are often designed to accommodate hydraulic pressure connections for the means of mitigating the chance of a leak. Furthermore, digital pressure gauges feature ample customization in terms of firmware so that specific conditions or attributes can be monitored.

Despite a variety of pressure gauges being available on the market, the two most common types are Bourdon tubes and bellow gauges. Bourdon tubes create measurements by turning pressure into mechanical energy, that of which adjusts a dial on the gauge to convey a reading. As Bourdon tubes vary in design to account for different pressure ranges, it is important that one procures a device that could work for their particular needs. Bourdon tubes are fairly simplistic in their design and operation, simply featuring a tube of metal where one end is fixed and the other attached to a sensitive lever mechanism. As pressurized fluid enters the curved tube and increases pressure, the tube will begin to straighten. This pulls at the lever mechanism, adjusting the needle on the gauge to create a reading in proportion to the pressure.

Bellow gauges are fairly similar to Bourdon tubes, albeit featuring a spring element for measurement. As pressure increases within the assembly as fluids enter the device, pressure will build up against the spring, causing it to compress. This energy is then transferred to gears, allowing for the pressure dial to adjust for a measurement to be made.

Whether you need to conduct pressure measurements for testing equipment or for maintaining the performance of operating machinery, having the right pressure gauge for your needs can make a major difference.
