Abstract:
1. A system for determining characteristics of two rolls configured in a nip press, comprising: a strip configured to be placed in the nip press; a plurality of sensors embedded in the strip that is configured to generate signals representative of the pressure and/or the nip width between the two rolls, the plurality of sensors being configured in a plurality of sensor banks; interface circuitry that facilitates addressing of individual ones of the plurality of sensors via a data processing system, the interface circuitry comprising a plurality of multiplexer circuits respectively coupled to the plurality of sensor banks, each of the multiplexer circuits being responsive to a sensor address to select an output signal of one sensor contained on the respective sensor bank coupled thereto; and a plurality of processors respectively coupled to the plurality of multiplexer circuits that is responsive to a multiplexer selection address to selectively enable one of the plurality of multiplexer circuits; wherein the plurality of sensors embedded in the strip that are configured to generate signals provide a substantially continuous representation of the pressure and/or the nip width along a length of the two rolls.
