The BLA light array’s intuitive design makes it easy to use: it consists of a powerful red-light laser and a high-resolution CCD receiver and operates completely independently - without any other accessories such as a controller, PC, or special software. The BLA has a range of up to 2 m and resolution of 0.01 mm.
The multifunctional device offers numerous modes of measurement such as object diameter, object position, gap width, gap position, edge position, etc. In addition, the user can use intuitive, on-device buttons to teach-in up to six different objects and blank out disruptive objects in the measuring field (blanking). Parallel use of the different measuring modes is also possible: for example, checking the diameter of the object at the same time as determining the position of the object.
The BLA is very versatile, even in particularly harsh conditions, thanks to its robust metal housing. Additional features include: high-precision position monitoring and detection; quick and easy sorting of parts according to size and/or diameter; and precise detection of web edges, even with semi-transparent materials.
In one application, two BLA sensors are used to check whether the bottles in a filling machine have been correctly filled and sealed. The first BLA sensor immediately detects the width of the bottle neck and compares it with previously taught-in values. Once the cap is screwed on, the other BLA sensor checks whether the seal is complete and fits tightly against the bottle.
