Abstract

This invention provides a lubricant feed state monitoring sensor and a lubricant feed state monitoring device, which can surely monitor the feed state of lubricant fed to lubricated parts, such as bearings of a rotary machine, at positions near the lubricated parts. The sensor that monitors the lubricant feed state is directly mounted on a device, requiring the supply of lubricant or in a lubricant feed pipe to detect the supply of lubricant. The sensor comprises a detection member disposed so that its one end is fixed and the other end is positioned in the flow of lubricant. The detection member further comprises a piezoelectric element or a strain gauge for converting strain produced by the flow of lubricant to electric signals when the lubricant is being supplied.
