Abstract: An automated system, which has a high speed, for detecting longitudinal tears of conveyor belts is proposed. It is based on the use of two methods: first – non-contact measurement of the width of the belt using ultrasonic sensors and second – using ultrasonic radiation directed to the control point. Also, the advantage of the system is that to reduce the likelihood of false alarms, duplication of the sensors operation is used (the "two out of two" scheme operates when the signal for an emergency stop of the conveyor is given only when two types of sensors are triggered simultaneously). The use of the developed system to detect longitudinal tears of conveyor belts is currently relevant and has a number of economic and technical ad-vantages over existing devices. The system is fully capable of performing the main tasks that were laid down during its creation, which are: a non-contact principle of operation, a quick shutdown of the conveyor in the event of a belt break to prevent a longer longitudinal break, a decrease in the likelihood of false alarms, high reliability, ease of installation. The technical means for creating the system have been selected, a block diagram of the operation algorithm has been developed, and a connection diagram has been designed. The system can work with equipment from different manufacturers.
