ABSTRACT:
The level of heat treatment of metal strip in a process line is determined by first strain gauge producing a voltage proportional to longitudinal strip tension; selective means deflecting the strip in a lateral direction without materially effecting tension; second strain gauge producing a voltage proportional to lateral force and an amplifier means combining such voltages; setable means coupled to amplifier means output for establishing a predetermined output signal for a specific strip size; means producing voltage proportional to the lateral deflection; means differentiating between a voltage indicative of a gradual strip difference and a voltage resulting from sudden strip deflections; and means combining differentiated signal and latter voltage to produce a combined signal indicative of heat treatment level.
Continuous strip monitoring by strip twisting to cause lateral deflection includes means producing a third voltage proportional to deflection amount and a fourth voltage proportional to strip thickness; and means combining the first and fourth voltages and second and third voltages to produce a combined signal indicative of heat treatment level.
