Apparatus for measuring camber in rails

摘要

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.
