About This Product

■Applications

・Measures moisture content in oils such as heavy oil and lubricating oil. Can be used for monitoring moisture content and controlling alarms. ・Since the dielectric constants of oil and water differ significantly (oil: approximately 2-3 / water: approximately 80), this device measures the oil's dielectric constant and continuously measures moisture content based on this change. ・Oil is passed through a coaxial cylindrical electrode. A single calibration is performed for each oil type, enabling highly accurate and stable moisture measurement. ・Features include temperature compensation and compatibility with multiple oil types.

■Features

・Simple electrode structure minimizes pressure loss and extends service life. ・High-precision capacitance transducer ensures stable moisture measurement. ・Temperature compensation eliminates measurement errors even when the oil temperature changes (e.g., from room temperature to 60°C). ・The display has an oil type registration function, making it compatible with a wide variety of oils.

■Operating Principle

・When the sensor (electrode) is filled with only oil, the transducer displays "2." On the other hand, when the container is filled with water only, it will read "80" (this detects the difference in dielectric constant; 80 is the dielectric constant of water, and 2 is that of oil). -If even a single drop of water is added in this state, the converter will change significantly to the positive side. The moisture meter detects this difference. -If you adjust the converter so that it reads "0V" when there is only oil, and "1V" when 1% water is added to the oil, it will read "2V" when 2% water is added. -In other words, the capacitance changes linearly with the amount of moisture.
