Abstract
A system (1) for measuring the dynamic pressure distribution between rolls (2 and 6) in a nip roll press comprises a roll (6) adapted to rotatably contact at least one other roll (2) in a press nip, having one or more sensors (4) thereon, for measuring the nip pressure at several locations along the roll length, wherein the measurements obtained by the sensors (4) are transmitted to a computer (18) and a display (20), to provide tabular, numerical and graphical representations of the pressure at one or more locations on the roll (2). Optionally, a control system (22) may be incorporated in the system (1) for determining the pressure distribution along the roll (2) and initiating corrective measures. The system (1) of the instant invention can further measure temperature variations, if desired, as thermal sensors (4) can be used on the sensing roll (2), or the computerized correlation scheme can relate sensor readings to temperature as well as pressure.
