    • Disclosed are an oil state monitoring method and an oil state monitoring device which monitor the state of degradation of oil used in machinery or equipment. In monitoring the oil state by the oil state monitoring method and by the oil state monitoring device, oil used in machinery or equipment is filtered when the degradation state of the aforementioned oil is to be monitored. By means of filtration, the oil content is removed from the filter which captured contaminants that were present in oil prior to filtration. Light is projected onto the filter from which oil was removed. The projected light detects the color components of the transmitted light which penetrated the aforementioned filter.
    • 公开了一种油状态监测方法和油状态监测装置,其监测机械或设备中使用的油的劣化状态。 在通过油状态监视方法监测油状态的情况下,通过油状态监视装置,在对上述油的劣化状态进行监视时,对机械或设备中使用的油进行过滤。 通过过滤,从过滤器中除去含油量,该过滤器在过滤之前捕获存在于油中的污染物。 光被投射到去除油的过滤器上。 投影光检测穿透上述过滤器的透射光的颜色分量。
