What is the measuring principle and functionality of the OilWear® sensor?

The Atten2 OilWear® sensors utilize advanced optical acquisition systems and digital image processing algorithms to monitor fluid contamination and condition in real-time. By capturing and analyzing periodic images of the fluid, these sensors detect particles and air bubbles larger than 4 microns, classifying them into six size ranges: >4, >6, >14, >21, >38, and >70 µm. This detailed particle analysis enables the identification of different types of wear and potential failure modes within machinery.
The measurement process involves the following steps:

1. Image Acquisition: The sensor captures images of the fluid at regular intervals.
2. Image Processing: Advanced algorithms analyze these images to detect and classify particles and bubbles based on size and shape.
3. Data Transmission: The processed information is transmitted via Modbus to the customer’s acquisition system, facilitating seamless integration with SCADA, PC, or PLC systems.
