FIELD: process engineering.
SUBSTANCE: proposed measuring roll comprises, at least, one measuring bar resting on transducers built in roll outer surface. Note here that measuring bar is composed of strip tension measuring bar for determination of strip tension temporal process and extends, in fact, along circular contour in one preset zone of roll circular contour. In compliance with another version, said bar extends inclined to roll axis and extends on one side along one preset width zone and, on opposite side, along one preset zone of roll circular contour. Flatness measuring bar comprises, at least, one strip tension measuring bear as reference measuring bar. Note here that flatness measuring bar is used for measuring one voltage signal depending upon time and describing width coordinate. Note also that reference measuring bar is used to measure one reference time-dependent signal irrespective of width coordinate and describing strip temporal process. Note that reference signal is filtered from tension voltage signal for determination of strip intrinsic tension process.
EFFECT: higher accuracy of measurement.
