Abstract: A contaminant sensor (1) for detecting magnetizable contaminants (7) present in a lubricant flow is disclosed. A permanent magnet (3) is arranged movably inside a sensor housing (2). A sensor element (6, 11, 13), e.g. in the form of a distance sensor (6) or a pressure sensor (11), is arranged to detect a displacement of the permanent magnet (3) inside the sensor housing (2), and an indicator is arranged to generate an alert signal when a displacement and/or a rate of change of displacement of the permanent magnet (3) inside the sensor housing (2) exceeds a pre-defined threshold value. The permanent magnet (3) is arranged to move inside the sensor housing (2) in response to magnetizable contaminants (7) collected on an outer surface of the sensor housing (2).

Abstract: A method involves directing lubricant to different consumers which are to be monitored via their lubricant. The lubricant is drained through drain lines connected to the consumers and directed to a tank. At least some the lubricant in the drain lines or the consumers is extracted into extraction lines. Flow from the extraction lines is selectively directed to a measurement device, which then measures a characteristic of the lubricant. A system for carrying out such a method is also provided, wherein the system includes a multiplexer for selectively directing flow from the extraction lines.

Abstract translation: 一种方法包括将润滑剂引导到不同的消费者，这些消费者将通过其润滑剂进行监测。 润滑剂通过连接到消费者的排水管排出并导向罐中。 排水管线或消费者中的至少一些润滑剂被提取到萃取管线中。 来自提取管线的流动被选择性地导向到测量装置，然后测量装置测量润滑剂的特性。 还提供了一种用于执行这种方法的系统，其中系统包括用于选择性地引导来自提取线的流的多路复用器。
