For the same system, such as the hydraulic system, we often see the earthquake-resistant pressure gauge and the seismic 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 the seismic pressure gauge and the seismic pressure gauge:
Shockproof pressure gauge:
The shockproof pressure gauge is based on the ordinary pressure gauge. The damping fluid is filled inside and the buffer mechanism is installed to reduce the impact of the environment vibration and the pulse of the medium on the instrument. The pressure gauge indicates stable and clear. The shockproof pressure gauge is suitable for places with severe environmental vibration, and can withstand medium pulsation, impact and sudden unloading, and the instrument indication is stable and clear. It is widely used in machinery, petroleum, chemical, metallurgy, mining, electric power and other departments to measure the pressure on copper and copper alloy non-corrosive media.
Seismic pressure gauge:
The anti-vibration pressure gauge consists of a gasket, a diaphragm set, a hook spring, a transmission indicating mechanism and an outer casing. The anti-seismic pressure gauge is mainly suitable for measuring pulsating pressure and is widely used in petroleum, chemical, machinery, coal, pharmaceutical and other industries. For example, for drilling, fracturing in oil production, the instrument has the characteristics of anti-blocking, and the measured medium cannot enter the inside of the meter, thus allowing the medium to have high viscosity, high particle size, easy solidification, etc., such as mud.
It can be seen that the working principle of the two is very similar to the applicable industry. So they can often be used interchangeably, and even many companies introduce them as the same product.
Stereo headphone is important components of audio equipment. It has a wide frequency response, low distortion, power saving, strong audio resolution, clear surround sound, and good music rhythm. Stereo headphone is divided into earphone and headphone, which has the difference of left and right channels. It cannot be used interchangeably. Otherwise, the fidelity of the sound source and the resolution of the source frequency will be directly affected.
