A vacuum pressure gauge is a commonly used tool for measuring gas pressure. It can be used to measure gas pressures below standard atmospheric pressure. Vacuum pressure gauges can be categorized as mechanical and electronic.
Mechanical vacuum pressure gauges measure vacuum pressure by converting gas pressure into a mechanical vector using a mechanical mechanism or spring. Electronic vacuum pressure gauges, on the other hand, use electronics to convert gas pressure into an electrical signal, which is then converted into a digital signal through a conversion circuit. These two types of vacuum pressure gauges have different applications.
