Measurement of process variable – pressure
Kouba, Martin ; Hammer, Miloš (referee) ; Konečný, Antonín (advisor)
The measurement of the process quantity of pressure is an important element and condition of the functionality of many industrial applications, especially in the environment of commodity production, transport, pharmacy, food industry and many others. In practise, there are many pressure measurement methods that are applied in different environments and conditions. The choice of measuring equipment depends on many factors, such as the measurement range, environment, sensitivity, response speed, or environmental resistance. The correct procedure in their calibration and determination of measurement uncertainties increase the credibility of the measurement results. The means of data transfer in a modern concept make it possible to better secure and speed up the transfer of information in the measurement chain. All of the above-mentioned facts, in sequence and in relation to each other, fundamentally affect the resulting reliability and effectiveness of the measurement of the process quantity. The study of the measurement of the process quantity of pressure from a comprehensive point of view will allow us to analyse the individual elements of the measuring chain and their interconnection. The content of the thesis provides a basic orientation to the issue of pressure measurement and captures the main trends in individual areas.
