Optical sensor e.g. light grid, for monitoring fire break in e.g. conveyor belt, has analysis unit to analyze characteristics, where region of fire break is bridged by acquiring non-safety critical objects to restrict report generation

摘要

The sensor has an analysis unit (6) for analyzing the object characteristics recorded with a light receiving unit, for accomplishing a differentiation of safety-critical and non-safety critical objects. A region of fire break (2) in a machine is bridgeable by acquiring the non-safety critical objects in the fire break, so that the penetration of objects in these bridged regions does not lead to the generation of object report.
