Abstract: An equipment management system is provided with an RFID provided for each equipment, an equipment position information storage unit, an equipment management data storage unit, an image information storage unit, a reader/writer, and a portable information terminal transmitting and receiving information with each storage unit. The image information storage unit has point group information and other image information of the inside of a facility. The equipment position information storage unit has installation position information of the equipment associated with the RFID and a virtual tag allowing reference to equipment management data on the equipment management data storage unit corresponding to the equipment and the image information associated with the equipment associated with the RFID in the image information storage unit.

Abstract: A lubricant-feed-state monitoring sensor disposed directly associated with a device fed with oily or fatty lubricant or a lubricant feed pipe for feeding lubricant to the device, for monitoring the feed state of lubricant by detecting the supply of the lubricant to the device, the sensor including a T-shaped member having a lubricant passage connected to the lubricant feed pipe and a detector insertion portion extending substantially vertically from a middle portion of the lubricant passage, into which a detector is inserted; wherein the detector is disposed such that a first end portion of the detector is fixed to a top portion of the detector insertion portion, and a second end portion is positioned in the lubricant passage without restraint, the detector undergoing bending deflection by displacement of the second end portion due to the flow of the lubricant, and the detector having a piezoelectric element that generates voltage by the bending deflection.
