A review and analysis of known works on the automation of control and
regulation-monitoring of the width of the working slots of the harvesting apparatus (НA)
of the cotton harvester, in particular, the automation of control and regulation of working
units, which determines the indicators of the quality of the harvest and the productivity
of the cotton harvester, is carried out. It has been substantiated that in order to increase
the efficiency of the functioning of the cotton picker, automatic control and management
systems are needed that perform the functions of information-measuring and control
systems that perform horizontal and vertical adjustment of the position of the harvesting
device and adjust the working gap according to the agricultural background, inform the
driver about other important parameters of the cotton picker and cotton-growing
machine-tractor units (CGMTU). It has been established that one of the most important
parameters to be monitored and regulated by the cotton harvester is the width of its
working slot (WWS), which determines the productivity and quality of the cotton
harvester collection. It was revealed that despite some progress in this direction, there
is still a lot of research work to be done on the development of intelligent converters,
sensors, instrumentation and control devices. At the same time, one of the main
element and node that determines the accuracy of control and regulation of the width of
the working slot is sensors that control and convert the width of the working slot into a
different type of signal proportional to them, convenient for further use, which is an
urgent issue. In this regard, the work considered and carried out a critical analysis of the
principles of construction and operation, methods and sensors for controlling the width
of the working slots (WWS), for example: contact with mechanical switches, inductive
and potentiometric sensors with outputs of the controlled parameters to various display
elements: numbered color lamps, displays, etc. The main characteristics, advantages
and disadvantages of the considered sensors are given, as a result of which it is
concluded that it is necessary to continue research and development in this direction
