Conveyor Speed Monitoring system DS-77 is designed to prevent and analyze possible emergency situations on the conveyor: determine slippage, transverse belt tearing, overload by the transported material, control the acceleration of the conveyor belt at the conveyor start.

Analysis of emergency situations
is performed according to the event data recorder and allows to reliably identify the reasons of emergency situations. The event recorder stores streaming information about the movement of the belt in non-volatile memory. In case of emergency conveyor stops, a graph of the speed change over the last 30 seconds before the stop is displayed
