Abstract
Photoelectric automatic measurement of lenghth on a belt conveyer has a lot of advantages, such as cheap cost, long lifespan, simple construction and convenient operation, etc. , which make it develop fast and apply widely. However, it is easily disturbed by many factors so that its precision is not ideal. How to improve the precision is one of the problems which need to resolve imperatively at present. This paper will discuss the reasons why the precision is not ideal and put forward a series of measures to correct the errors. At last, a schematic diagram to realize high-accuracy measurement of length are given.
