The present invention is directed to endless belts and fabrics for use in a process control loop which can be used in the production of the products specified in the specification. The belt is provided with means for emitting electromagnetic radiation upon excitation by an energy source. That is, the belt is provided with a sensor which emits electromagnetic radiation when excited by an energy source, such as an external one that is directed at the belt. A sensor is comprised of an electromagnetic radiation emitting compound dispersed within a matrix. The sensor may also contain a scattering material. The sensor can take the form of a filamentary material, coating or film that can then be incorporated on or in the belt. In operation, energy emitted from an energy source is directed at the belt. Upon excitation of the sensor by the energy, the sensor emits electromagnetic radiation, which is detected by a detector located nearby. Based upon the intensity and peak wavelength of the emission of electromagnetic radiation from the sensor, the machine operator can learn useful information about the operation of the belt and the conditions under which it is running.
