The JWF2-Q oil quality sensor is an intelligent sensor for on-line measurement of oil state changes, with its unique sensing structure and internal model. It makes it extremely sensitive to changes in oil quality, and can continuously and quickly react to changes in oil status in real time, which is stable for equipment reliable operation provides a strong guarantee. Oil quality is a comprehensive indicator of oil degradation. It reflects key factors such as acid value, wear condition, particle content, moisture, mechanical impurities, and additive breakdown. As a powerful tool for monitoring the condition of oil and its lubrication performance, direct oil quality monitoring covers a wide range of parameters and serves as a fundamental metric in oil condition analysis.
