Abstract
The paper considers the advantages of using smart pressure sensors in systems for measuring and controlling technological objects. Modern intelligent sensors that, in addition to the measurement process, convert the measured signals into typical analog and digital values, perform self-diagnosis of their work, remotely adjust the measurement range, pre-process measurement information, and sometimes a number of fairly simple, typical control and management algorithms. They have interfaces to standard / typical field digital networks, which makes them compatible with almost any modern automation equipment, and allows you to communicate with these tools and receive power from the power supplies of these tools. The technical features of the use of modern intelligent pressure sensors are considered. The functions implemented by intelligent sensors, their structural features and characteristics of the main data transfer protocols used in automation systems where these sensors are used are analyzed. The correction of temperature errors of the pressure sensor, which works according to the scheme of the tensor-resistive bridge, with the use of the capabilities of the LabVIEW software environment, is considered. Keywords: Smart pressure sensors, data transfer protocols, sensing element, LabVIEW software.
