Title:
VIBRATION INFORMATION TRANSMISSION APPARATUS AND VIBRATION MONITORING&sol ANALYZING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2004/017033
Kind Code:
A1
Abstract:
A vibration information transmission apparatus for improving efficiency of field wiring of a vibration monitoring&sol analyzing system includes transmitters (11−1 to n) for converting vibration information from vibration sensors (2−1 to n) for detecting vibration of an object to be measured, into an electric signal and outputting the electric signal to a digital network (DN). The transmitters (11−1 to n) includes in the same casing, a transducer circuit (18) for converting the vibration information from the vibration sensors (2−1 to n) into an analog electric signal, an A&sol D conversion circuit (19) for converting the analog electric signal from the transducer circuit (18) into a digital signal, and a network interface (20) for outputting the digital signal from the A&sol D conversion circuit (19) to the digital network (DN).
