Background. The actual problem in the development of new types of aviation products is the creation of angular displacement sensors with high stability, measurement accuracy and reliability. Materials and methods. The methods of integral and differential calculus, the theory of electric circuits and electromagnetic field were used to solve the problems. The computer-aided design system KOMPAS was used in the design of sensor structures. Results. As a result of this work, a three-channel angular displacement sensor and two versions of the secondary converter have been developed. The substitution diagram of transformer angular displacement sensor on the basis of which the expression defining dependence of output EMF value on angular displacement of the sensor rotor is obtained.
