As a pressure measuring instrument with elastic elements as sensitive components, vacuum pressure gauge has been widely used in the industrial field since its development and application, thanks to its high accuracy, convenient detection, and simple operation. Due to the fact that vacuum pressure gauges are mainly used for testing important processes in the industrial field, any inaccurate calibration of vacuum pressure gauges can inevitably have a significant impact on the stability and safety of industrial production.
The vacuum pressure gauge uses bullet line elements as sensitive components for sensing, which can measure and indicate instruments above ambient pressure, allowing measurement personnel to understand the pressure value of the measuring instrument through the display of pressure changes. According to the purpose of vacuum pressure gauges, they can be classified into ordinary vacuum pressure gauges, ammonia vacuum pressure gauges, oxygen vacuum pressure gauges, shock resistant vacuum pressure gauges, electric contact vacuum pressure gauges, digital compact vacuum pressure gauges, and double needle vacuum pressure gauges. When applying pressure gauges in practical situations, the selection of vacuum pressure gauge types needs to be based on the requirements of the measuring instrument. In general, the maximum range scale of a vacuum pressure gauge is 1.5-3.0 times the maximum working pressure of the container. However, in order to ensure the accuracy and safety of the pressure detection of the vacuum pressure gauge, the multiple needs to be controlled at around 2 times during actual measurement, and the diameter of the vacuum pressure gauge cannot exceed the range of 100 millimeters.
The vacuum pressure gauge needs to be installed in an easily observable position: When selecting the installation position of the vacuum pressure gauge, it is necessary to choose an easily observable position as much as possible for installation, so that the vacuum pressure gauge can be fully observed and dirt treated. In order to improve the accuracy of the vacuum pressure gauge, it is necessary to install it in a location that is not directly exposed to sunlight and has high temperatures, to avoid radiation heat, freezing, and vibration caused by external factors.
That's all for the introduction about vacuum pressure gauges above. I hope it can be helpful for your understanding.
