Dec 31 2018 Conveyor belt speed timer Arduino or otherwise So to start off here is my problem I have to measure conveyor belt speed at work It is a very tedious process because the fastest belt speed is 12 IPM the slower being around 2 IPM It is very difficult to get consistent readings with a stop watch and measure something moving that slow The most accurate method for measuring conveyor belt distance and speed is to directly measure the belt surface itself This eliminates mechanical tolerances and inconsistencies created during conveyor manufacture or after conveyor components become worn An encodermeasuring wheel combination is typically used for this purpose
