HIPROFILE LITE

Laser Profile Gauge for hot & cold long products DANIELI AUTOMATION

HiPROFILE LITE is a laser based 3D measurement Features instrument providing non-contact on-line profile > Blur-free profile acquisition and minimum-noise HiPROFILE LITE shape inspection and dimension measurement for measuring either hot or cold rolled products. > No need for water and compressed air (electric From small rounds, squares and flats through rebar, power is the only utility required) HiPROFILE LITE provides the optimum solution to > Fully synchronized laser triangulation heads improve production performance and quality. > Specific algorithms for real profile measurement of rebar and Kocks-like sections Principle of operation > Alarms in case of out of tolerance products The HiPROFILE LITE system is based on laser- > Continuous real time production control & sectioning optical measurement techniques tracking and image processing algorithms.

Operating and installation costs are very low: the electrical supply is the only utility required to customers for gauge operation.

A wireless connection is available nearby the gauge to aid during periodic maintenance.
