1. A sensor plate (1) serving as a plain bearing or guide element for rolling mills (200), comprising:
a plain bearing surface (2) that can be brought into contact with a component and is subject to wear during operation of a rolling mill (200); and
a plurality of wear sensors (121), which are arranged in form of an (m×n) matrix integrated into the plain bearing surface (2) with at least one of the parameters (m) and (n) being two or greater than two,
a plurality of measuring sensors (10) accommodated in an integrated manner in the sensor plate (1) and arranged in form of an (a×b) matrix adjacent to the plain bearing surface (2) in such a way that the measuring sensors (10) are not subject to wear on the plain bearing surface (2) and are capable of capturing forces and/or strains and/or deformations acting on the sensor plate (1), which arise as a result of surface, line or point contact of the sensor plate (1) with the component,
wherein the parameters (a) and (b), with which the (a×b) matrix for the arrangement of the measuring sensors (10) is formed, each consist of integer values selected from the numerical range {1-100},
wherein the wear sensors (121) are suitable for capturing a material removal on the plain bearing surface (2) and for this purpose each comprise an electrical resistor, which is formed from at least one electrical conductor (122), and
wherein the wear sensors (121) are mechanically removed with the material removal on the plain bearing surface (2).
