    • PROBLEM TO BE SOLVED: To provide a lubricant oil deterioration sensor which is capable of instantaneously determining the type and amount of contaminant in lubricant oil for a machine.SOLUTION: A lubricant oil deterioration sensor 139b comprises a body part 10 which is fixed to an arm 113 of an industrial robot and a replaceable unit 60 which is replaceable for the body part 10. The replaceable unit 60 comprises a white LED 72 and an RGB sensor 73, and the body part 10 comprises a gap forming member 20 provided with an oil gap 20a which is formed in it for lubricant oil 131a to enter into and is disposed on an optical path 10a from the white LED 72 to the RGB sensor 73. The gap forming member 20 transmits the light emitted by the white LED 72, and the body part 10 and the replaceable unit 60 respectively comprise engagement parts 43, 83 which engage with each other in a state in which the positional relation of the gap forming member 20, the white LED 72 and the RGB sensor 73 becomes a prescribed positional relation.
    • 要解决的问题:提供一种能够瞬时确定机器润滑油中的污染物的类型和量的润滑油劣化传感器。解决方案:润滑油劣化传感器139b包括固定到臂的主体部分10 工业机器人113和可更换为主体部分10的可替换单元60.可替换单元60包括白色LED 72和RGB传感器73,并且主体部分10包括间隙形成构件20,间隙形成构件20设置有油隙 20a,其形成在其中,用于润滑油131a进入并被布置在从白色LED72到RGB传感器73的光路10a上。间隙形成构件20透射由白色LED72发射的光和主体 部分10和可更换单元60分别包括在间隙形成构件20,白色LED72和RGB传感器73的位置关系变为一个状态的状态下彼此接合的接合部43,83 规定的位置关系。
