Last night at around 7 o'clock, a customer from Langfang, Hebei called us to order a pressure gauge, telling us the range, dial diameter, installation thread, and specifically mentioning the accuracy level requirements. At first, we thought it was a pointer pressure gauge, but later the customer said it had higher accuracy, preferably 0.2 level, with a digital display. Later, we recommended a digital pressure gauge with battery power to the customer and sent pictures for reference. The purchased customer was very satisfied before seeing the product and immediately expressed their desire for this type of digital pressure gauge.

Today we will talk about the difference between digital pressure gauges and analog pressure gauges?

Firstly, let's talk about the digital pressure gauge:

What is the difference between a digital pressure gauge and a pointer pressure gauge? A digital pressure gauge is a digital display that uses a digital display screen to show pressure data. The pressure value is directly presented in numerical form on the display screen, and the reading is very accurate, accurate to a few decimal places, which is very important for situations that require high-precision pressure measurement. Moreover, digital display is not affected by visual angles, and there is no reading error that may occur due to different observation angles like a pointer pressure gauge.

Next, let's talk about the pointer pressure gauge:

What is the difference between a digital pressure gauge and a pointer pressure gauge? A pointer pressure gauge is a pointer display that displays pressure values by rotating the pointer on the dial. The dial is marked with pressure units and scale values, and the position of the pointer corresponds to the corresponding pressure magnitude. This display method is more intuitive, and people can quickly make a rough judgment of pressure based on the position pointed by the pointer. However, the accuracy of its readings is limited by the scale division, which may pose certain difficulties when reading small pressure changes.

Advantages of using two products:

What is the difference between a digital pressure gauge and a pointer pressure gauge?

1. Product accuracy:

Digital pressure gauges have high measurement accuracy. Its accuracy level can usually reach 0.05-0.5 level. Digital pressure gauges utilize advanced sensor technology and electronic circuits for pressure measurement and data processing, reducing errors caused by mechanical component wear and enabling more accurate pressure measurement;

The accuracy level of pointer pressure gauges is mostly around 1.0-2.5. This is because its measurement principle relies on mechanical transmission and pointer rotation, and mechanical components may experience wear, deformation, and other issues during long-term use, which can affect measurement accuracy.

2. Product reliability and stability:

The digital pressure gauge has complex electronic components inside. Under normal working conditions, it has good stability and reliable measurement results. However, if in a harsh environment with strong electromagnetic interference or high humidity, electronic components may be affected, leading to measurement deviations. Digital pressure gauges typically require a power source (battery or external power) to function. Its advantage is that it can conveniently store measurement data, and some also have data transmission functions, which can transmit measurement data to remote devices for analysis and processing, making it more intelligent to use;

The structure of a pointer pressure gauge is relatively simple, and under normal conditions, it can maintain a relatively stable working state without being subjected to severe external impact or excessive use. However, its adaptability to the environment is poor, for example, in environments with large vibrations or drastic temperature changes, its pointer may shake or become inaccurate. The operation of a pointer pressure gauge is relatively simple and does not require an additional power source. As long as the installation is correct, the pressure reading can be visually observed. However, it cannot store measurement data or perform remote transmission.

In summary, in the future, when choosing between digital pressure gauges and analog pressure gauges, let's take a look at the differences between digital pressure gauges and analog pressure gauges? This way, a suitable pressure gauge can be selected to meet the on-site working conditions.
