Abstract
A vibration coupling stud for use in a vibration monitoring system includes digital memory and temperature sensing devices. Data is transferred between the vibration coupling stud and a vibration monitor. Data stored in the stud may include asset identification code, measuring point identification, prior measurement data, machine or bearing part numbers, and alarm limits.

13. A vibration monitoring system comprising:
-
a stud comprising a machine connection point and a vibration monitor connection point;
a vibration monitor comprising a coupler for removably coupling to said stud at said vibration monitor connection point so as to detect machine vibration through said stud, said vibration monitor further comprising a first memory circuit, wherein said first memory circuit stores one or more types of data selected from the group consisting of alarm limits, point identification data, date, time, and bearing data, said vibration monitor further comprising a data communication interface associated with said vibration monitor;
a second memory circuit mounted to said stud, wherein said second memory circuit stores one or more types of data selected from the group consisting of alarm limits, bearing part number, bearing quality characteristics, lubrication information, installation date, signal filtering parameters, defect indication frequency, and date stamped value of a parameter measured during a previous data collection operation, and wherein said second memory circuit is connected to a data communication interface associated with said stud, whereby data stored in said vibration monitor is transferred from said vibration monitor to said stud and data stored in said stud is transferred from said stud to said vibration monitor through said data communication interfaces. - View Dependent Claims (14, 15, 16)
