  • Apparatus for monitoring the moisture content of hay as it is being formed into a bale
    Patent number: 4868491
    Abstract: An improved hay baler and a moisture sensor for monitoring the moisture content of hay as it is being formed into a bale is disclosed. The sensor is adapted for mounting internally to the side of a baling chamber. It includes a pair of spaced apart elongated electrodes supported on an insulating material and exposed for contacting hay passing through the baling chamber. The electrodes are connected to a resistance network for measuring the electrical resistance in hay passing between the electrodes. An indicator is in electrical communication with the resistance network for indicating the moisture content in the hay being formed into a bale to an operator.
