No matter what kind of job it is, there always needs some instruments to help finish the task. The advantage of instruments are remarkable: it can help reduce costs, save time and become more accurate. Although instruments have been developed and are widely used in many areas during recent years, some special fields still need special instruments. 548014-1 application field and working principle is one of those special fields needing special instruments.

548014-1 is widely used in pressure tests, vacuum tests, air flow tests, gas flow tests, and other related tests. As the measuring instrument for the determination of the pressure and the flow of various gases, it has extraordinary advantages than other instruments; first, the accuracy of measurement is higher; secondly, emission method is flexible and can adapt to different kinds of gasses; thirdly, it has a wide range of uses, and it is easy to understand.

The working principle of 548014-1 is as follows: Firstly, connect the device with external pressure or flow source and bridge feedback obstruction of the signal from external to feedback signal processing; Secondly, the feedback signal is digitized by the A/D conversion and is amplified; After the signal is filtered and amplified, compensation would be taken; then the PI comparison would be made; Finally, the control signal is sent to display via the D/A conversion.

In order to ensure the accuracy of 548014-1, the following parameters should be taken care of: First, the pressure should be kept at a relatively stable level during testing; secondly, the working temperature should be maintained at a certain level; thirdly, the leakage and filter loss should be kept lower as much as possible; fourthly, the air flow should be continuous and no changes suddenly.

548014-1 application fields and working principle are interesting and essential for many fields. In view of the existing situations, it is necessary to improve the performance of 548014-1 in terms of its safety and reliability. In the future, people need to research more about 548014-1 related areas to make it better.
