What is the liquid inside an anti-vibration pressure gauge? Why is this substance added? What is its function?
The liquid in an earthquake-resistant pressure gauge is *oil. It serves as a buffer. The shock-resistant pressure gauge is suitable for use in environments with severe vibrations; it can withstand pulsations of the medium, shocks, and sudden load releases, ensuring stable and clear readings. It is widely used in industries such as machinery, petroleum, chemicals, metallurgy, mining, and power generation to measure the pressure of media that are non-corrosive to copper and copper alloys.
Those with high requirements use silicone oil, while others use glycerin; the difference lies in the operating temperature.
Generally, silicone oil or glycerin is used, and the reason was explained very clearly on the second floor.
It is mostly silicone oil; other media are selected based on environmental factors such as temperature and explosive environments, in order to provide shock absorption and prevent the pointer from vibrating at too high a frequency. Generally, locations where seismic pressure gauges are installed are equipped with annular pressure transfer pipes.
