Stainless Steel Pressure Gauge Cyclical Changes
- Oct 10, 2017 -

A part of the user friend in the use of stainless steel pressure gauge process, found that the indicator of the instrument frequently appear to swing the problem. We are in the analysis of the problem, Stainless Steel Pressure Gauge we learned that the original user in the installation of the instrument, the stainless steel pressure gauge in the workplace vibration is relatively large, Stainless Steel Pressure Gauge so this led to the instrument of the pointer also appeared frequently swing.

So on this issue, we think that this is not the quality of the stainless steel pressure gauge itself. In fact, the common stainless steel pressure gauge pointer appears to oscillate frequently, usually related to the vibration of its working environment. That is to say, it is related to the equipment installed on the stainless steel pressure gauge. If the vibration amplitude of the device during the working period is large, Stainless Steel Pressure Gauge then naturally it will cause the amplitude and frequency of the pointer to swing.

Of course, if the vibration amplitude of the device is very small, or it is not obvious, then the amplitude of the stainless steel gauge pointer will be small and low. However, Stainless Steel Pressure Gauge if the vibration of the instrument is more severe, when the left and right swing of the meter is larger than the ±5%, then it is difficult to read the indicator. In addition, the sharp swing of the stainless steel pressure gauge is also related to the properties of the measured medium.

If we use the stainless steel pressure gauge to measure the pressure is fluctuating pressure, then naturally will cause its pointer to swing left and right. Stainless Steel Pressure Gauge This is because the pressure changes over time and changes periodically, one becomes larger, the other becomes smaller, and the instrument's pointer changes as the pressure changes. However, the frequency will be much lower than the vibration.

1. The instrument must be installed vertically, Stainless Steel Pressure Gauge and strive to maintain the same horizontal position as the measuring point, otherwise the additional error caused by the liquid level difference shall be counted accordingly.

2. Handling and installation should avoid collision and vibration, including the environment and contact instruments, pipelines and so on.

3. Instrument should be in ambient temperature of -40℃~+70℃, relative humidity is not greater than 85% of the site use, the use of ambient temperature if the deviation is too large, Stainless Steel Pressure Gauge must consider the temperature additional error.

4. The instrument shall not exceed the 2/3 of the measuring limit when measuring the stable load, and shall not measure the fluctuation pressure exceeding the 1/2 of the measuring upper limit and the minimum pressure, in both cases, should not be lower than 1/3 of the measurement upper limit. Stainless Steel Pressure Gauge The measured pressure should be maintained in the meter full range of about two-thirds appropriate.

5. In the measurement of corrosive media, the possible crystallization of the medium, viscosity of large medium and upheaval fluctuations in the pressure should be added isolation devices and buffering devices.

6. The ambient air in the instrument storage environment cannot contain harmful impurities which can cause its corrosion, and the relative humidity of the air can not be too large.

7. The instrument should be properly kept before and after use, avoid collisions and strong vibrations.

8. The instrument shall be inspected regularly (at least once three months) and found to be defective and repaired in a timely manner.

9. Please describe the medium you want to measure each time you make the order to use better quality material.
