MEASURING, counting, and detecting objects of differing shape, colour and size are tasks that are beyond most sensors. Balluff has solved the problem simply, economically and flexibly with its measuring photoelectric BLG 1 light grids.
The dense beam arrangement allows even small objects down to approximately 4mm in diameter to be reliably detected.
Light grids have a digital switching output and a 0-10V analogue output. The switching output becomes active as soon as an object in the measuring field interrupts at least one beam. The analogue signal is proportional to the number of beams covered by the object.
The compact and rugged metal housing of the BLG 1 light grid is immune to electromagnetic and optical effects. Status and diagnostic indicators simplify start up and maintenance of the sensors.
The fully integrated electronics eliminate separate processing units. All these features make the BLG 1 measuring light grid an economical and easy to use sensor system.
The BLG 1 light grid is available in measuring field heights of 100, 150, and 300mm and ranges from 850 to 2100mm.
Applications can be found in every area of industry and automation wherever measuring, counting and detecting different shapes and sizes are important.
