Applications
Applications in general
•Any elementary detection problems in which a standard
sensor such as a proximity switch or light barrier is not
applicable
•For all metal sections, ferrous and nonferrous
Annealing lines
Detection of holes in the weld seam in order to shut off
cooling water to prevent water from entering the inside of
the tube
Tube-forming processes
Detection of the weld seam to place the tube in the posi-
tion required for bending
Transverse weld detection
Detection of butt welds joining tubes and bands
End-to-end testing
Detection of the start of a new test piece.
Mantling processes
Detection of internal features such as connectors and
holes that are covered by insulation, rubber, etc.
Speed range
0.5 m/min – 1200 m/min (1.64 – 3937 ft/min) depending
on type of production
