Abstract:
1. A lubrication monitoring device for monitoring a lubricating condition of a lubricator feeding an oil droplet at a predetermined time interval by a discharge nozzle comprising a nozzle orifice, the lubrication monitoring device comprising: a pair of electrodes disposed in a proximity of the nozzle orifice; a capacitance detecting portion for detecting a variation of a capacitance between the pair of electrodes, the capacitance varying in conjunction with a varying amount of oil discharged from the nozzle orifice in a space between the pair of electrodes; and a determination portion for determining whether the oil droplet is fed at the predetermined time interval, the determination being made based on a detection result supplied from the capacitance detecting portion, wherein the nozzle orifice comprises an inclined portion that faces an electrode of the pair of electrodes.
