LAP and Sema Systemtechnik have developed a product for the laser-optical inline straightness measurement of bars and tubes up to 8000mm in length. With the Straightness Check X-Line, a 100% quality control in the production cycle is possible. Due to its modular structure, a wide variety of requirements can be configured. The non-contact system measures the straightness deviation in mm/m over the entire length of the material in real time (measuring frequency 800Hz). A complete measurement cycle from feeding in the profile to leaving the system takes just under two seconds.
The optoNCDT 1760-1000 long-range laser sensor by Micro-Epsilon also measures at distances of up to 2m with up to 7.5kHz.
