  • Conveyor-belt moisture control sensor apparatus
    Patent number: 5303579
    Abstract: A conveyor-belt moisture control sensor apparatus (10) includes a sensor device (12) having an electrically-insulative block (30) with two adjacent electrodes (32, 34) extending therefrom to contact a top surface (22) of a return portion (24) of a conveyor belt (26). Two wires (36, 38) are mounted on the electrically-insulative block and connected to connection ends of the electrodes at encapsulated points in the electrically-insulative block. A hinge mechanism (40) mounts the electrically-insulative block to a conveyor-belt support frame (44) for allowing the electrically-insulative block to rotate, thereby bringing the electrodes into contact with the conveyor belt. A drip guard (98) extends from the electrically-insulative block above the electrodes.
