Conveyors are the most efficient and cost-effective means of moving bulk commodities over short and medium distances. However, they consume large amounts of power and man-hours, in the form of cleaning and maintenance. The focus on suppliers is, therefore, to reduce both these elements, even though this may result in a higher initial investment cost for the operator. This development is ongoing and achieved more by evolution than technical breakthroughs. But so-called "smart" conveyors are an area where modern electronics can achieve a significant performance upgrade by adapting technology employed for other applications.
