Vibration-resistant pressure gauges are mainly used for pressure testing in metallurgy, electric power, petroleum, chemical, light industry, machinery and other industrial sectors. The pressure gauge relies on measures such as internal flushing of damping oil and supporting buffer devices. Has good shock resistance. The shock-resistant pressure gauge is suitable for occasions where the pressure of the measured medium has a strong pulse change or pressure shock and is often suddenly unloaded in the production process, as well as places with large environmental vibrations. The meter can measure the average value of the pulsating pressure of gas and liquid to overcome the damage caused by the strong pulse of the medium and the environmental vibration to ensure the accuracy of the reading.
The outer casing of the stainless steel shock-resistant pressure gauge is made of stainless steel (semi-steel for short), which can be used in harsh environments with corrosiveness and greater vibration.
