Smart Sensor for Real-Time Monitoring of Machine Oil Health

Industry: This paper is relevant to the industrial machinery sector, focusing on the
maintenance and health monitoring of rotating and reciprocating machines, such as engines,
turbines, and other mechanical systems that rely on lubricating oil.

Challenge: Detecting early signs of machine failure through the monitoring of lubricating oil
is crucial for preventing breakdowns and ensuring efficient operation. Traditional methods of oil
condition monitoring can be limited in sensitivity and require frequent manual sampling and
analysis.

Extraordinary Aspects of the Paper: This research introduces a multi-functional sensor
that integrates several miniaturized sensing elements to provide comprehensive monitoring of
lubricating oil. Key innovations include:

Wear Debris Detection: Utilizes two sensing channels to detect particles larger than 50
micrometers.

Viscosity Measurement: Employs micromachined elements to measure oil viscosity
above 12.4 cSt.

Moisture Detection: Measures moisture levels greater than 50 ppm.

Parallel LC Resonant Method: Enhances sensitivity and signal-to-noise ratio for both
wear debris and moisture detection.

High Throughput: Capable of processing 50 mL/min, making it suitable for online, real-
time monitoring without interrupting machine operation.
