THE ISSUE OF RESEARCH OF MANUFACTURING TECHNOLOGY OF HIGH-TEMPERATURE LINEAR DISPLACEMENT SENSOR BASED ON METAL-CERAMIC INDUCTANCE COILS

Abstract

Background. Despite the high modern level of science and technology development, the problems of physical measurements remain relevant due to extreme operating conditions of primary measuring instruments (sensors), which take place in the rocket-space technology, including the problems of measuring displacements. he development of a displacement sensor operating at high temperatures of up to 600 °C imposes restrictions on the materials and wires used to manufacture inductor coils, due to the fact that there are few materials that are sufficiently strong to withstand such high temperatures (ceramics, seals). Materials and methods. Methods of integral and differential calculus, theory of electric circuits and electromagnetic field were used to solve the tasks. A computer-aided design system was used in the design of sensor structures AutoCAD. Results. As a result of the conducted work on the development of a linear displacement sensor, a large technological reserve was obtained for further work on the creation of high-temperature displacement sensors with different measurement ranges for the products of rocket and space technology.
