Online oil saturation moisture sensor for mineral oil and ester oil
The contamination of hydraulic oil and lubricating oil with moisture can cause significant operational issues when the concentration is high, and it is the leading cause of failures.
Performance and Function
To measure the relative humidity of oil, it directly displays the saturation level of moisture in the oil.
• 0%: Completely dry oil.
• 100%: The oil is fully saturated with water. Any additional water will not dissolve and will become free water, beginning to emulsify.
Mineral oils have low water absorption, indicating that 500 ppm is close to the saturation limit, increasing the likelihood of free water. In contrast, ester oils have a relatively high water absorption rate, showing approximately 15% saturation at 500 ppm.
Relative humidity must also consider temperature characteristics. Warm oil can dissolve more water than cold oil. Therefore, even relatively dry oil at high temperatures can suddenly produce free water when the oil temperature drops.
By detecting the saturation moisture content of oil, regardless of the type or temperature of the oil, we can contribute to the preservation of the system environment.
