Pressure gauge plays a vital role in industrial production and equipment monitoring. However, maintaining the clarity of pressure gauge display under different light conditions, whether in dim environment or strong sunlight, is a technical challenge.
For traditional pointer pressure gauge, its readability depends largely on the contrast between the pointer and the scale. In dim environment, it can be equipped with a backlight function to illuminate the dial through the built-in light source so that the pointer and scale are still clearly visible in the dark. Under strong light, the design of the dial needs to consider anti-glare treatment, such as using matte material or adding a sunshade to reduce light reflection and keep the reading accurate.
Digital pressure gauge directly displays the value through LCD or LED screen, which greatly improves the intuitiveness and accuracy of the reading. In low light conditions, digital pressure gauges are usually equipped with a backlight function to ensure that the screen can be clearly displayed in any lighting conditions. At the same time, high-quality digital pressure gauges will also use high-contrast displays and anti-glare designs to keep the reading clear even in direct sunlight.
In addition, in order to further enhance readability and durability, the screen surface of the pressure gauge is usually specially treated, such as adding protective glass or transparent protective cover to prevent scratches or stains from affecting the display effect. These designs not only improve the aesthetics of the pressure gauge, but more importantly, ensure its reliable use in various environments.
In summary, both the traditional pointer pressure gauge and the modern digital pressure gauge use a variety of technical means to ensure the clarity of the display under different lighting conditions. These designs not only improve work efficiency, but also ensure the accuracy and safety of industrial production and equipment monitoring.
