Abstract
A perforated roll (10) of a fiber web machine includes a roll shell (19), holes (13) extending through the roll shell, and a sensing system (14) arranged in the roll shell. The sensing system (14) includes at least one pair of leads (16), to which one or more sensors (15) have been connected. At least one pair of leads is composed of flat leads (17.2, 17.2), which are arranged in the roll shell side by side. A prefabricated sensor sheet (26) may be prepared for a perforated roll of a fiber web machine, such that holes may be drilled therethrough to communicate with the roll shell holes (13).
