Performance Advantages of the RF Admittance Level Sensor: High Resolution and Excellent Linearity

https://www.sowaysensing.com/blogs/Advantages-of-the-RF-Admittance-Level-Sensor.html

The SFC5 Series RF Admittance Level Sensor from Shenzhen Soway Tech Limited (Soway) is designed to provide precise and reliable liquid level measurement. Its performance is highlighted by two key strengths: high resolution and excellent linearity, making it well-suited for applications where accurate level monitoring and stable signal output are essential.

High Resolution for Precise Level Monitoring

The SFC5 Series offers a 1 mm measurement resolution, allowing it to detect small fluctuations in liquid level. This high resolution ensures that every change in the medium—whether water, oil, viscous liquids, or chemical fluids—is accurately captured, supporting precise monitoring and control across various industrial liquids.

Excellent Linearity for Reliable Signal Output

The RF admittance measurement principle provides a highly linear relationship between liquid level changes and output signals. The sensor outputs include:

0.5–4.5 V analog signal

4–20 mA standard industrial signal

RS485 Modbus digital output

As the liquid level rises or falls, the output follows a predictable and proportional trend across its full measuring range of 80–3000 mm, ensuring straightforward interpretation of measurements without the need for additional correction curves.

Repeatability for Stable Measurement

To support linear performance, the SFC5 Series maintains a repeat error of less than ±1% FS, ensuring that measurements remain stable and repeatable across multiple cycles. This high repeatability enhances reliability in continuous level detection or switch/alarm control scenarios.

Why This Matters

By combining 1 mm resolution, high linearity, and excellent repeatability, the SFC5 Series RF Admittance Level Sensor offers reliable performance for a wide range of liquids—including water, oil, and viscous or chemical fluids. Its robust design, with no moving or elastic components, ensures durability and consistent operation in demanding industrial environments.
