Abstract
A system for measuring nip width for a nip present between two rolls includes: (a) a sensor assembly; (b) a resistance-measuring unit that measures an electrical resistance; (c) first and second leads, the first lead being connected to a first strip of the sensor assembly adjacent a first end of the first strip, the second lead being connected to a second strip of the sensor assembly; and (d) a controller operatively associated with the resistance-measuring unit, the controller including computer readable program code, the code including a plurality of data sets, each of the data sets representing a relationship between resistance of a sensor and environmental temperature.
