      Shenzhen Soway Tech Limited (Soway) is an experienced manufacturer in the sensing and measurement industry and a trusted innovator in liquid level control technology. The SFC5 Series RF Admittance Level Sensor provides accurate and reliable measurement of various liquids, viscous substances, and chemical solutions with corrosive properties.

       

      With its advanced RF admittance technology, this sensor overcomes the common issue of electrode buildup while retaining the advantages of capacitive measurement, making it a precise solution for industrial level detection.

       

      Tailored to Your Application Needs

       

      With the SFC5 Series RF Admittance Level Sensor, you can select the right configuration based on your specific application, container type, and sensor requirements. Soway offers flexible measuring ranges from 80 mm to 3000 mm, ensuring millimeter-level resolution and adaptability to diverse setups.

       

      Two product systems are available:

       

      Integrated RF Admittance Level Sensor – probe and electronics combined into one compact device.

       

      Split RF Admittance Level Sensor – designed for high-temperature or high-pressure conditions, where the probe and electronics are separated for durability.

       

      Robust Design for Long-Term Use

       

      Thanks to its wear-free structure and high-quality materials, the RF Admittance Level Sensor is built for reliable operation in various industrial environments.

       

      Operating temperature: Integrated probe: -40℃ ~ +85℃; Split probe: -55℃ ~ +200℃

       

      Pressure rating: up to 2.5 MPa

       

      Protection level: IP65

       

      Accuracy: ±2% FS (water, dielectric constant ≥25), ±4% FS (oil, dielectric constant ≥5), ±5% FS (low-dielectric media)

       

      High resolution: 1 mm with repeat error <±1% FS

       

      These specifications provide stable and accurate level monitoring across a range of media.

       

      Advanced RF Admittance Technology

       

      By simultaneously measuring capacitance and resistance, the RF Admittance Level Sensor eliminates measurement errors caused by material buildup. An RF signal in the frequency range of 15–400 kHz ensures precise admittance-based detection.

       

      Key technical features include:

       

      Measurement accuracy across water, oil, viscous, and low-dielectric media with specified FS tolerances

       

      Multiple output options: 0.5–4.5V, 4–20 mA, RS485 Modbus

       

      On-site calibration: zero-point, full-scale, and range adjustment via buttons

       

      Display option: when fitted with a display gauge, liquid level can be directly viewed locally

       

      Find the Perfect Level Measurement Solution

       

      The SFC5 Series RF Admittance Level Sensor from Shenzhen Soway Tech Limited delivers precise, reliable, and durable liquid level detection. Whether for continuous monitoring, point-level alarms, or operation under challenging industrial conditions, Soway provides a solution that matches technical requirements.
