What is the difference between seismic pressure gauge and seismic pressure gauge?

For the same kind of system, such as hydraulic system, we often see the shock-resistant pressure gauge and the shock-resistant pressure gauge appear at the same time, so what is the difference between the two? First, let’s take a look at the introduction of seismic pressure gauges and seismic pressure gauges: Seismic pressure gauges: On the basis of ordinary pressure gauges, shock-resistant pressure gauges are filled with damping fluid and equipped with a buffer mechanism to reduce severe environmental vibration and the pulse of the medium. For such systems, such as hydraulic systems, we often see shock-resistant pressure gauges and shock-resistant pressure gauges appearing at the same time, so what is the difference between the two? First, let’s take a look at the introduction of shock-resistant pressure gauges and shock-resistant pressure gauges: Shock-resistant pressure gauges: On the basis of ordinary pressure gauges, shock-resistant pressure gauges are filled with damping fluid and equipped with a buffer mechanism to reduce severe environmental vibration and the pulse of the medium. The influence of the pressure gauge is stable and clear. The shock-resistant pressure gauge is suitable for places with severe environmental vibration, and can withstand medium pulsation, impact and sudden unloading, and the indicator is stable and clear. It is widely used in machinery, petroleum, chemical, metallurgy, mining, electric power and other departments to measure the pressure of non-corrosive media on copper and copper alloys. Anti-vibration pressure gauge: The anti-vibration pressure gauge is composed of sealing gasket, diaphragm group, hook spring, transmission indicating mechanism and shell. Seismic pressure gauges are mainly suitable for measuring pulsating pressure and are widely used in petroleum, chemical, machinery, coal, pharmaceutical and other industries. For example, it is used for drilling and fracturing in petroleum production. The instrument has the characteristics of preventing 'blocking'. The measured medium cannot enter the inside of the instrument. Therefore, the medium is allowed to have high viscosity, high particle size, and easy solidification, such as mud. It can be seen that the working principles and applicable industries of the two are very similar. Therefore, they are often used interchangeably, and even many companies introduce them as the same product.
