First Claim
1. An online bearing monitor for controlling the lubricating activity of a bearing luber, comprising:
- a) a lubricant level sensor capable of sensing the level of lubricant in the luber;
b) a lubrication flow control mechanism comprising part of the luber and capable of receiving signals to control the flow of lubricant to the bearing;
c) a transducer module comprising at least one online bearing condition sensor;
d) a data gathering and processing segment capable of receiving and processing data from the transducer module and from the lubricant level sensor and capable of producing output data;
e) a platform for data processing capable of receiving the output data from the data gathering and processing segment and comprising computing hardware capable of storing and executing software capable of transforming the output data from the data gathering and processing segment into signals able to cause the lubrication control mechanism to increase or decrease lubricant flow from the luber;
f) a central monitoring station; and
g) a communications system capable of transmitting information in both directions between the data gathering and processing segment and the data processing platform on the one hand and the central monitoring station on the other and between the data processing platform and the lubrication flow control mechanism.

Abstract
An online bearing monitor is provided that is threaded to the lubrication port of a bearing of a machine. The online bearing monitor of the present invention contains a temperature and vibration sensor, a lubrication level sensor optionally detachably coupled to the lubrication device, on board intelligence, and both wire and wireless electronics. The monitor provides for two-way communication to detect the lubrication and maintenance needs of a machine bearing. The monitor processes and stores temperature and vibration signals on site to determine corrective measures. The corrective measures can be conveyed wire or wirelessly to remote stations.
