An apparatus for controlling the moisture content of an endless moving belt. A conductor for electrically conducting a signal abuts a roller that provides electrical contact between the conductor and the belt. The roller is rotatable with respect to the conductor and supports the belt as it moves. A circuit connected to the conductor monitors the belt resistance and indicates when the belt resistance is above a preset maximum thereby indicating that the moisture content of the belt has fallen below a predetermined minimum. A spray system responsive to the circuit sprays the belt with water and increases the moisture level of the belt as long as the moisture level is below the predetermined minimum.
