Technical Field

[0002] Mechanical equipment requires lubricating oil for lubrication to ensure the stable operation of the mechanical equipment. In particular, some large equipment (such as automobiles, engineering vehicles, fans, etc.) will be equipped with a lubricating oil system. However, after long-term use, the lubricating oil will have impurities such as metal particles caused by mechanical wear. It is necessary to test the lubricating oil in time to check whether the lubricating oil has exceeded the service life. The existing sensors for detecting lubricating oil are mostly single sensors, with little and relatively single detection data, which is inconvenient to use. Furthermore, the detection part of the existing oil sensor and the main board (data receiving board) are mostly set in the same space. If there is oil leakage in the detection part of the sensor, it is very easy to cause the main board to be contaminated, resulting in the need to replace the main board, increasing maintenance costs.
