Pressure gauges that work very similarly to applicable industries
2012-2-7 9:34:49

We often see seismic pressure gauges and seismic pressure gauges appear at the same time, so what's the difference between the two?


:耐震压力表是在普通压力表的基础上,内部填充阻尼液并加装缓冲机构,减轻环境剧烈振动及介质的脉冲对仪表的影响,压力表指示稳定清晰。 Shock-resistant pressure gauges : Shock-resistant pressure gauges are based on ordinary pressure gauges, which are filled with damping fluid and equipped with a buffer mechanism to reduce the impact of severe environmental vibrations and medium pulses on the instrument. The pressure gauge instructions are stable and clear.

The shock-resistant pressure gauge is suitable for places with severe vibration in the environment. It can withstand medium pulsation, shock and sudden unloading, and the instrument indication is stable and clear. Widely used in machinery, petroleum, chemical, metallurgy, mining, power and other departments, measurement

Pressure on non-corrosive media to copper and copper alloys.

:抗震压力表由密封垫,膜片组,叉簧,传动指示机构和外壳组成。 Anti-seismic pressure gauge : The anti-seismic pressure gauge is composed of a gasket, a diaphragm group, a fork spring, a transmission indicating mechanism and a housing. 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, for oil drilling, fracturing, the instrument has the characteristics of preventing "blocking". The measured medium cannot enter the interior of the instrument. Therefore, the medium is allowed to have high viscosity, high particle size, and easy to solidify, such as mud.


It can be seen that the working principles and applicable industries of both are very similar. So they can often be used interchangeably, and even many companies introduce them as the same product.



Application overview of seismic pressure gauge:


The anti-vibration pressure gauge is composed of a pressure guiding system (including joints, spring tubes, current-limiting screws, etc.), a gear transmission mechanism, an indicating device (pointer and dial), and a casing (including the case, cover, glass, etc.).


The housing of the shock-resistant pressure gauge is air-tight, which can effectively protect the internal parts from environmental influences and pollution.


The shock-resistant pressure gauge is a meter filled with a damping liquid (generally silicone oil or glycerin) in the housing, which can resist the vibration of the working environment and reduce the pulsating influence of the medium pressure.

Installation precautions for seismic pressure gauges


1. The ambient temperature of the instrument is -40 ~ 70 ℃, and the relative humidity is not more than 80%. If it deviates from the normal operating temperature of 20 5 ℃, the additional temperature error must be taken into account.


2. The instrument must be installed vertically, and strive to maintain the same level as the measurement point, such as additional errors caused by excessive difference into the liquid column, you do not need to consider when measuring gas. When installing, block the explosion-proof port on the back of the case to avoid affecting the explosion-proof performance.


3. The measuring range of the meter in normal use: It should not exceed 3/4 of the upper limit of measurement under static pressure, and should not exceed 2/3 of the upper limit of measurement under fluctuations. Under the above two pressure conditions, the minimum measurement of the large pressure gauge should not be lower than 1/3 of the lower limit.

All vacuum parts are used when vacuuming.


4. If the meter pointer fails or the internal parts are loose or cannot work normally during use, it should be repaired or contact the manufacturer for repair.

5. The instrument should avoid vibration and collision to avoid damage.


6. When ordering, please indicate: the model and name of the meter; the measuring range of the meter; the accuracy level of the meter deviates from the requirements of the positive packaging and others.


7. Special design according to user requirements.
