Product Features
High Precision & Stable Detection Performance
Equipped with a high-precision capacitive measurement chip and built-in temperature compensation and linear correction algorithms, the sensor effectively eliminates detection errors caused by ambient temperature changes and oil medium dielectric fluctuation. It delivers highly linear and repeatable oil level detection data, ensuring long-term stable and accurate monitoring results without signal drift.
No Mechanical Wear & Long Service Life
Adopting fully electronic non-contact detection structure with no floating balls, connecting rods or other mechanical moving parts. It avoids mechanical fatigue, jamming, abrasion and corrosion failure caused by frequent liquid level fluctuation, greatly reducing later maintenance frequency and replacement cost, and adapting to 24-hour continuous industrial operation.
Strong Environmental Adaptability & Anti-Interference Ability
The whole machine adopts sealed industrial-grade protection design, with excellent dustproof, waterproof and anti-corrosion performance. It can resist electromagnetic interference, vibration and oil medium erosion in complex industrial environments, stably operate in high and low temperature working conditions, and is suitable for various harsh factory and equipment operation scenarios.
Wide Compatibility & Easy Integration
Supports standard universal signal output, which can be perfectly matched with industrial PLC, controller, display instrument and automatic control system. It is compatible with various lubricating oil, hydraulic oil, gear oil and other industrial oil media, with strong versatility, and can be quickly integrated into new and old mechanical and automation equipment systems.
Working Principle
The CL-204 capacitive oil level sensor operates based on the parallel plate capacitance detection principle. The sensor probe acts as the main electrode, and the metal tank wall or built-in reference electrode forms the auxiliary electrode, with the oil and air between the two electrodes serving as the dielectric medium. Since the dielectric constant of industrial oil is much higher than that of air, when the oil level rises or falls, the proportion of oil and air in the sensor detection electric field changes synchronously, resulting in a linear change in the overall capacitance value of the sensor. The built-in high-precision chip captures tiny capacitance changes in real time, converts the capacitance variation corresponding to oil level height into standard analog or digital electrical signals, and outputs stable and readable level data, realizing real-time, continuous and accurate monitoring of oil level.
