RF Admittance Level Sensor: Application Conditions and Process Parameters
To ensure reliable and accurate performance of the RF Admittance Level Sensor in real-world operating environments, it is essential to consider specific process conditions during selection, installation, and use. Proper understanding of the medium properties, temperature, pressure, and environmental factors helps maintain the long-term stability and measurement precision of the SFC5 Series.
Medium Conditions
The RF Admittance Level Sensor developed by Shenzhen Soway Tech Limited (Soway) is suitable for the continuous or point-level detection of liquids such as water, oils, viscous liquids, and chemical solutions. Different media have different dielectric and resistive characteristics, which directly affect the measurement signal and accuracy.
For media with a high dielectric constant (ε ≥ 25), such as water, the typical measurement accuracy can reach ±2%FS. For media with lower dielectric constants, such as oils or adhesives, the accuracy is around ±4–5%FS. Selecting a suitable probe length and performing proper calibration according to the medium type ensures optimal measurement performance.
Temperature and Pressure Conditions
The SFC5 Series RF Admittance Level Sensor operates reliably across a wide range of temperatures and pressures.
Temperature range: Integrated probe –40°C to 85°C; Split probe –55°C to 200°C
Rated working pressure: ≤ 2.5 MPa
Within these limits, the sensor maintains stable performance and signal integrity. For long-term stability, the product should always be used within its rated operating conditions to ensure safety and reliability.
Process and Ambient Temperature
The sensor’s probe and electronic unit should operate within their specified temperature ranges. When process temperatures approach the upper limit, the ambient temperature surrounding the transmitter should be maintained within safe limits. If necessary, users can employ measures such as thermal insulation or remote installation to protect the electronics and maintain stable output performance in high-temperature environments.
Medium Viscosity, Build-up, and Conductivity
The RF Admittance Level Sensor features strong resistance to material buildup and coating, minimizing errors that occur with conventional capacitive sensors. However, for highly viscous or adhesive media that may cause accumulation on the probe surface, it is recommended to use the split-probe version or models with buildup compensation to ensure consistent signal quality and measurement accuracy.
These design advantages allow the sensor to perform reliably in complex media conditions, including those involving viscous fluids, sedimentation, or partial coating.
By carefully evaluating the medium properties, temperature and pressure conditions, and installation environment, users can fully utilize the performance advantages of Soway’s SFC5 Series RF Admittance Level Sensor. Designed with robust structure, high sensitivity, and strong anti-fouling capability, this sensor provides stable and precise liquid level measurement across a wide range of industrial applications.
