ABSTRACT:
An electronic camber measuring device for hot rails utilizes the radiant energy of the rails for measuring the amount of camber imparted to the rail in a rail mill by measuring deflection in the end of the rail with respect to the centerline of the mill. Phototransistors are coupled to a readout console through digital circuitry. The readout console has a visual and audible alarm capability for indicating out-of-tolerance camber and a recorder for recording the camber and temperature of the rails.
