SIMULATION OF THE PRESSURE DIFFERENCE SENSOR

Abstract

Background. A characteristic feature of the global development of information and control systems in the late XX – early XXI century is the increasingly widespread use of pressure sensors in all spheres of life. Sensors are used in industrial branches, in automation of production processes, in automobile, aviation and railway transport, rocketspace and aviation engineering. Due to the complexity and labor intensity of the technological process of pressure sensors, a special role in the process of their design methods of simulation, the use of which can significantly reduce the time and cost of developing pressure sensors. Materials and methods. As a method of research, simulation modeling was used, in which the sensor under study is replaced by its model, with which experiments are conducted in order to obtain information about the object. The specialized software Solidworks was used in the experiment to avoid expensive and time-consuming cycles of design-build-testing. Results. As a result of modeling the sensor membrane to increase its sensitivity to pressure drop, the membrane thickness and the diaphragm deflection range were determined. And also the dependence of the deflection value on the thickness of the membrane was determined.
