Background. The subject of this study is to transformer rotary encoder with digital output. The aim is the development and research of transformer angular displacement sensor operating in harsh conditions with the specified metrological and performance.
Materials and methods. A equivalent circuit and mathematical model of rotary encoder, which allows to derive an expression for the calculation output emf sections measuring winding transformer sensor. The structural scheme secondary converter designed to convert the sensor output signals to a digital serial code.
Results. Derived basic expression for calculating the emf transformer winding sections measuring sensor according to the movement of the core, which allowed the design phase to determine the sensitivity and the nature output signal.
Conclusions. The resulting technical and operational characteristics, combined with ease of manufacturability and design allow the use of a sensor designed for measurement and control systems.
