摘要

A length measuring gage for a steel plate mill has a pulse generator connected to a work roll for providing pulses which are representative of length increments of the circumference of the roll. The pulses are counted in an accumulator which is gated to count when roll separating force load cells indicate usable product is being rolled. A variable ratio gear box connected between the work roll and the pulse generator permits calibration of the pulse generator to provide an accumulator total directly in inches for a particular measured work roll circumference.
