| 摘要 | PURPOSE:To monitor easily and surely the amt. of oil by converting dropping of the oil to an electrical output and processing the same thereby detecting the amt. of the oil. CONSTITUTION:The lubricating oil fed through a lubricating oil supply pipe into an oil flow controller is changed in flow rate by a needle and a tapered hole and arrives at a bearing by dropping in a dropping passage. The quantity of the light arriving at a photodetector 43 from a light projector changes at every passage of the oil drop between the light projector and the photodetecotor 43 during the dropping, thus giving a rise to an output change of the photodetector 43. The output terminal of the photodetector 43 is connected to the input terminal of a waveform shaping circuit 50 and is shaped to a square wave. The amt. of the oil is detected by processing the square wave. | ||||||
