Product Name: CAP3024-21113 Intelligent Oil Level Gauge
Product Description:
The CAP3024-21113 Intelligent Oil Level Gauge is manufactured using advanced radio frequency capacitance detection technology, supplemented by industrial-grade range measurement system temperature drift compensation technology and automatic compensation technology for changes in the dielectric constant of liquid-phase media. The CAP3024-21113 Intelligent Oil Level Gauge is specifically designed and manufactured for oil level and oil-water interface measurement applications in industrial environments where the composition of the gas (vapor) phase medium is relatively stable.
By leveraging the relationship between changes in oil level and oil-water interface and the resulting capacitance changes on the measuring probe, the detected capacitance changes are processed through dedicated system software after temperature drift compensation of the measurement system and compensation for changes in the dielectric constant of the liquid-phase media. This outputs a two-wire 4–20 mA analog current loop proportional to the oil level change and four sets of SPST (NO) solid-state relay contacts corresponding to the oil-water interface change.

Technical Features
1. Two-wire current loop with isolation between the measurement system and the current loop;
2. Automatic compensation for temperature drift in the measurement system;
3. Automatic compensation for changes in the dielectric constant of the liquid-phase media;
4. Excellent electromagnetic compatibility characteristics certified by CE;
5. Continuous measurement of liquid level and interface;
6. Superior linear measurement with smaller resolution units;
7. Low power consumption, no moving parts, and excellent craftsmanship;
8. Resistant to high temperature, high pressure, and strong corrosion;
9. Chinese operating environment, easy calibration, and self-diagnosis.
