Abstract :
Modern scientific and technical progress is
closely connected with development and automatics
introduction. Automatic control is carried out on the basis
of the information at use of a complex of means of
automatics, including the various automatic devices
serving for reception, transfer, transformation and storage
of the controllable information, its comparison with
program, transfers of the command information for
influence on operating process. Contact less electric
devices of automatics have found application in watching
systems for synchronous transfer of linear and angular
moving on distance. Recently, contact less watching
systems of the big and small linear moving are
developed. They differ simplicity of designs and
manufacturing techniques, the big reliability, sensitivity
and accuracy of the control of a target signal (moving and
effort).
