Precautions for Using Pressure Gauges

For enhancing the accuracy of the pressure gauge, there are several precautions for you when measuring the pressure.

Ⅰ. Make the operating steps of the pressure gauge more normative

To complete the pressure measurement and guarantee the accuracy of data, the measurement operation procedures of pressure gauges shall be standardized and controlled, which leads to the total improvement on the measurement work. For instance, before implementing the pressure gauge, the inspection on whether the device works or not shall be done on the pressure gauge.

Ⅱ. Operate pressure gauges correctly

The choice of safety pattern pressure gauge is the most significant basis of the measurement work. There are various pressure measurement devices at present and the measurement staff shall choose the safe and reliable equipment for the real pressure measurement on basis of the flourishing knowledge of performance and characteristics of the pressure gauges. Meanwhile, the development of pressure gauges types shall catch up with the development of science and technology of the era, which can promote the accuracy of measurement results. The proper use of pressure gauges not only meets the requirements of pressure measurement but also reduces the statistic error caused by manual operation during the measuring process.

Ⅲ. Focus on the temperature influence of pressure gauges

During the measuring, the temperature is also a key factor that would influence the pressure measurement result. Under the different temperature influences, the results vary widely. Therefore, before pressure measuring, the personnel shall conduct temperature detection on the measurement site, analyze the temperature status, and then select the appropriate temperature environment for pressure measurement. Pressure measurement is usually carried out between 15 and 25 degrees Celsius, which ensures that the pressure gauge is operating properly and the measurement results are accurate.

Ⅳ. Focus on the pressure resistance test of pressure gauges

Focus on the pressure gauge test is an important link to ensure the accuracy of the measurement results in the pressure measurement work, through the pressure test can effectively determine its performance and accuracy. If there is no pressure resistance test in the pressure measurement process, it will lead to the pressure gauge in the follow-up work cannot fully play a role, or even its internal structure will be seriously damaged, which leads to the pressure measurement work cannot being carried out. Based on this, pressure measuring personnel in the measurement work must take the pressure resistance test to ensure the normal operation of the pressure measurement instrument, and standardize the detection means and timely replace the pressure gauge which does not meet the standard.

Ⅴ. Focus on the errors of pressure gauges measurement

To ensure the accuracy of pressure measurement results, it is necessary not only to pay attention to the operational problems in the measurement process but also to consider various errors. Given the errors in the process of pressure measurement, it is necessary to analyze the causes of the errors and take effective measures to strictly control and standardize the errors caused by human operations and system factors, to optimize the overall level of pressure measurement. At the same time, the average value of the measurement results can be obtained through multiple pressure measurement methods, and appropriate adjustments and improvements can be made to avoid the error of the pressure measurement results and ensure the accuracy of the pressure measurement results.
