What Are Digital Pressure Gauges and How Do They Work?


Pressure gauges measure the pressure of a liquid or a gas relative to the atmosphere or the difference between two points. Pressure gauges are widely used all over the world and have long been essential in the food and beverage industry, resources industry, marine industry, agriculture industry and a list of others.

While analogue pressure gauges (which have a needle that responds to changes in pressure) remain the instrument of choice for some, digital pressure gauges (which feature microprocessors and advanced sensors) are growing in popularity with each passing year. Here are some reasons why:

Highly accurate

Accuracy is incredibly important to ensure safe working environments and avoid unplanned downtime, damaged products, process quality issues, increased costs and a host of other potential issues. Digital pressure gauges are accurate because they are made with modern engineering, converting pressure to an easily measurable electronic signal.

The digital pressure gauges that GTS Gauges stock including the PDR100PDR250 (pictured above), PDR500 and PDR1000 that form a part of the PDK range are all highly accurate. They range from 0.5 per cent to 0.025 per cent full-scale accuracy.

Increased readability

Most digital pressure gauge displays have distinct numerals to eliminate the parallax error and to enable workers to read and record data quicker and easier than it would be to interpret the needle of an analogue gauge. They also commonly feature a backlight LCD display to increase visibility under poor lighting conditions or shadows.


Versatility and durability

At GTS Gauges we stock modern digital pressure gauges in Perth which are capable of displaying a wide range of pressure units (including mbar, bar, MPa, mmH20, inHg, mmHg, kgf/cm2, atm, psi, kPa) and being less reliant on mechanical parts, are designed to withstand everyday use in industrial applications. The PDR500, for example, has a silicone protection cover and a 1P66 waterproofing rating.


Other great benefits

Some of our higher-end digital gauges such as the PDR500 and PRD1000 include advanced features such as Bluetooth data logging and smartphone connectivity.
