Digital pressure gauge is a kind of instrument used to measure the pressure of liquid and gas, and then display it digitally. The sensor installed in the meter converts the obtained pressure value into a digital reading.
Pressure gauges are widely used in industrial and automation industries. Their applications are getting more and more attention in new areas of healthcare and energy production.
The display may be backlit and includes various pressure-related data collection and display functions, including data logging, min/max display, peak alarm, unit selection, tare function, etc.
Pressure gauge manufacturers are adopting new and advanced technologies to gain market advantage. As the market is flooded with various pressure gauges, it is very difficult to choose any pressure gauge.
When the instrument is used in a hazardous environment, it can obtain intrinsic safety certification.
It's can help you choose the best digital pressure gauge:
6 steps to choose the best digital pressure gauge
1. Check the accuracy of the pressure gauge
One of the main differences between mechanical pressure gauges and digital pressure gauges is accuracy. The accuracy provided by the latter is considered higher. The accuracy level is 0.5% to 0.05% of full scale.
Generally speaking, the price of gauges increases with accuracy. Before finalizing any specific instrument, you must accurately assess the requirements of the application.
2. Determine durability
As we all know, digital meters are very durable because they have no moving parts. They come in different types and are suitable for different applications.
For example, some meters need to be moved around for applications such as testing and require higher robustness, while some applications require fixed meters.
Determine the type of durability you need. Facts have proved that this may be a cost-effective way, because the durable pressure gauge will save the recurring cost of replacing it.
3. Prioritize readability
Readability is one of the main reasons why digital pressure gauges are superior to mechanical types. In addition to the digital display, these digital meters are backlit for easy reading and easy-to-read presentations in dark environments.
You must also choose the correct display size. Evaluate these requirements for your application and check the readability of the pressure gauge accordingly. There are various types of pressure gauges on the market, and their prices vary according to their functions. Determining the technical details required will save you money and increase your productivity.
4. Assess the operating environment
Every digital pressure gauge must operate in certain environments, including parameters such as ambient temperature, humidity, particulate matter in the air, and certain chemicals. There may be extreme temperature or environmental conditions that are highly corrosive.
This situation requires a highly durable pressure gauge. Any discrepancies may cause malfunctions and false readings, which may lead to inaccurate final results.
After determining the installation area and application of the digital pressure gauge, you must list the environmental conditions that the pressure gauge will be exposed to, and then find a suitable digital pressure gauge that can withstand it.
5. Find a suitable connection size meter
The pressure gauge can adopt various connection methods, such as NPT, JIS and DIN. These connections are associated with the dial size.
To choose the best connection size, you need to determine other requirements such as process pressure, space limitations, leak integrity, weight, and gauge size. In addition, the location of the connection should also be determined. Connections that meet all these criteria can be approved.
6. Select a pressure sensor whose components are compatible with the process fluid
The pressure sensor of the digital pressure gauge is made of different materials. The process fluid is an important part of determining the type of pressure sensor element.
7. Choose shell and joint material
According to the needs, choose the right material. Such as 316 stainless steel housing and 316 stainless steel joints.
If the use environment is relatively poor, you should choose a better and more durable material. For details, please consult our customer service!
If they are not compatible, corrosion may occur, resulting in inaccurate results. A better option is to check the compatibility of the process fluid and the pressure sensor element before purchasing a digital pressure gauge.
A) Diaphragm seals can be used with digital pressure gauges to make them suitable for applications.
Digital pressure gauges have a wide range of prices and types. Choose the right pressure gauge manufacturer, they can provide you with the best range of pressure gauges and help you choose.

Frequently asked questions about digital pressure gauges
The first quarter. How to choose a digital pressure gauge for my application?
A. The digital pressure gauge is required when digital read out or analog output is required. Digital Pressure gauges need to be carefully chosen according to the application. The wetted parts of the digital pressure gauges should be compatible with the process media. Since they are electronic devices, the process temperature has to be within the maximum allowable limit. Digital pressure gauges are more precise and offer higher accuracy and resolution compared to analog gauges. So selection of correct accuracy and resolution depending on the application is very important step in selection of digital pressure gauge.
Q2. Can we configure different engineering units in digital pressure gauges?
A. Every digital pressure gauge comes with pre-defined engineering units. The number varies from manufacturer to manufacturer. Most digital gauges from reputed manufacturers offer option to select from multiple engineering units.
Q3. Can Digital Pressure gauges be used for outdoor process applications?
A. Yes, Digital Pressure gauges can be used for outdoor process applications. However one must to ensure that the product is IP65 rated and designed to work in the respective ambient conditions.
Q4. How are Digital Pressure gauges are powered?
A. Digital Pressure gauges are powered by AA, AAA, 9V battery, Button batteries, loop power, AC and DC power. Battery is preferred for calibration applications and Loop power, AC or DC in process applications or where continuous service is required.
