Some Problems in the Process of Measuring Pressure with Pressure Gauges

As the continuous development of science and technology, the use of a large amount of advanced equipment and instruments have played extremely important role. However, meanwhile, on basis of their functions, the internal structures are requested to be more advanced as well as the accuracy. Therefore, precise computing on data of these equipment and instruments shall be done to avoid all kinds of problems occurring during the manufacturing process and the measurement by pressure gauge is a key computing segment of producing activity whose results determine the quality of producing activity. Furthermore, some problems of pressure measurement shall be noticed to promote the accuracy of pressure gauge results.


There are many problems in the measurement of pressure gauges. Take aviation industry as an example, the following are the main problems in the process of pressure measurement.


Ⅰ. The measurement steps of pressure gauges are not rigorous


In the aviation industry, the verification requirement of pressure gauge measurement is high, which requires every link in the process of the pressure measurement should be with high accuracy and high reliability and it is almost not allow for the possibility of failure, and is also high requirement of pressure measurement. And as for the technical personnel, they not only need professional knowledge ability, also need to treat rigorous earnest attitude of metrological work pressure. However, in the actual situation, there are many pressure measurement technicians whose professional knowledge and ability are poor, and lack of rigorous work attitude and responsibility, and their measurement steps are not so strict, leading to a series of problems.


Ⅱ. Improper operations of pressure gauges


A safety pattern pressure gauge is the most basic instrument in the process of pressure measurement. In the aviation industry, the correct use of the pressure gauge by the metrology personnel can accurately measure the pressure value in the flight test process. On the contrary, if the pressure gauge is improperly used, it will bring great negative impact to the flight test. However, in the actual situation, because some staff did not test the performance of the pressure gauge before using it, such as detecting the deviation of the pointer, whether the dial number is fuzzy and other problems, the measurement results of the pressure gauge appeared errors, which directly affected the effect of flight test.


Ⅲ. Improper cognition of pressure gauges


In flight test, the error of pressure measurement results will seriously affect the flight test and even destroy the normal operation of the aircraft. Therefore, in the process of pressure gauge measurement, the relevant provisions should be in strict accordance with and a rigorous working attitude shall be maintained to reduce the error value of pressure measurement to the minimum and verify more accurate data. However, in the actual situation, some pressure measurement personnel still have a wrong understanding of the error value, and their pressure measurement method is not appropriate, resulting in serious deviation of the verification measurement results.


In a word, in the face of the development of the new situation, pressure measurement work is facing higher level requirements. It is necessary to pay attention to many problems in the process of pressure measurement, and take effective measures for the existence of problems, strict control of the pressure measurement process, but also to ensure the standard operation of measuring personnel. Meanwhile, better grasping and controlling the influence of human factors and environmental factors in the pressure measurement process can improve the accuracy of the pressure gauge measurement results.
