Background. In the conditions of rapidly developing information-measuring technologies, it is necessary to quickly and most accurately approach the design and development process of modern sensor-converting equipment (SCE). Determination of a method for measuring a particular parameter is an urgent and not a trivial task. The use of modern methods of computer modeling makes it possible to preliminarily assess the operability of the SCE, cut off irrational options and start developing a future product. The purpose of computer simulation of a strain-gauge absolute pressure sensor is the selection of optimal design solutions for further design of an absolute pressure system.
Materials and methods. As a research method, computer modeling was applied using the SolidWorks software with the Simulation module, which made it possible to avoid expensive and lengthy design cycles and obtain acceptable schematic and design solutions for the further manufacture of prototypes of strain-gauge pressure sensors and systems based on them.
Results. As a result of computer modeling, the design parameters of the sensitive element under the influence of a nominal pressure of 1.6 kgf/cm2 were selected, the displacements of the membrane and the beam were determined when a concentrated load of 2.1 kg was applied to the rod, depending on the tolerance values of the geometric dimensions of the sensitive element.
