Abstract
An infrared ray sensing device for the rotor of a rotary rengenerative heat exchanger that includes a sensor 34 having a viewing lens 38 at the end of a moving support arm 36. The sensor is adapted to view the infrared ray emission from the rotor. As the arm moves along a path adjacent the rotor it comes into alignment with a fixed nozzle 44 that ejects a blast of cleaning fluid over the entire surface of the lens to remove dust deposits therefrom and thus maintain the lens in a clean condition.
