KSLV651-A Compact Level Sensor with IP68 Protection FEP Probe and Self-adaptive Measurement
The KSLV651-A Series Intelligent Capacitive Level Sensor is carefully designed by KACISE and is suitable for various complex level measurement applications, including wastewater, oils, chemical media, and environments with large variations in temperature and pressure. The product features a single-probe capacitive design with no moving or elastic parts, offering high reliability, impact resistance, easy installation, and excellent cost performance. It can replace RF admittance, radar, ultrasonic, and magnetostrictive level instruments to achieve precise level measurement across a wide range of media.
The core probe is made of FEP material and is paired with a high-precision RF capacitive detection circuit. Through precise temperature compensation and linear correction by the internal processor, it automatically converts changes in the medium’s level into a standard electrical signal. The product supports automatic calibration and self-adaptive measurement, providing long-term stable level data in different media and complex conditions without manual intervention.

- Excellent anti-fouling capability, with strong resistance to material buildup, condensation, and bubbles
- Simple structure with no moving parts, ensuring high reliability and minimal maintenance
- Multiple signal output options available for easy integration with different systems
- Unaffected by the temperature, density, pressure, or other properties of the measured liquid
- Maximum operating temperature ≤ 250 °C; maximum operating pressure ≤ 4 MPa
- Good sealing performance, with optional products rated up to IP68 protection
- Comprehensive protection against lightning, overcurrent, overvoltage, and power polarity reversal
- Long-term stability: ≤ 0.1% FS per year
- Temperature drift: ≤ 0.02% FS/°C (within the range of −40 °C to +80 °C)
- Measurement accuracy:
- For measuring ranges ≤ 300 mm: absolute error within ±3 mm (including 3 mm)
- For measuring ranges of 300–700 mm: accuracy class 1.0
- For measuring ranges of 700–2000 mm: accuracy class 0.5
