A critical process
while melting steel is the firing of the carbon arc between
graphite electrode and the materials to be melt.
In order to optimize this process our camera system checks
the wearout of the electrode between the processes.
According to the requirements of an electromechanical highly
charged environment – 100.000 ampere and 1.200 volt
– we have chosen an insensitive smart-camera. The results
are transmitted via an 100 meters optic fibre to the PLC.
To protect the camera and its lenses we stored the system
in a special protective housing. The high pressure within
the housing prevents the deposit of dust and dirt and keeps
clearance low. The air cooling assures that the heat in the
environment doesn't affect the vision-system.
