Talk about knowledge related to pressure gauges

Whether in chemical or industrial enterprises, pressure gauges are one of the most common monitoring and measuring instruments. A pressure gauge is like our eyes. Through a pressure gauge, on the one hand, we can monitor the working conditions of the medium inside the equipment during operation, control the pressure within the normal range, and protect the safety of production equipment; On the other hand, through pressure gauges, we can understand the changing state of materials during the production process, allowing certain process parameters to be controlled under given conditions. The importance of mastering process parameters to provide reliable basis for operators to monitor, control, and adjust production is self-evident.

The so-called pressure gauge refers to an instrument used to measure pressure below or above atmospheric pressure based on atmospheric pressure. In order to better understand pressure gauges, we need to understand the basic concepts related to pressure.
