Supporting Electronics for RF Admittance Level Sensor

The RF Admittance Level Sensor from Shenzhen Soway Tech Limited (Soway) is designed to convert liquid level variations into standard electrical signals for monitoring and control. These sensors rely on changes in the admittance of the liquid medium, which combines both capacitance and resistance, to provide precise and reliable measurements.

Signal Conversion

As the liquid level changes, the sensor detects variations in electrical admittance and converts these changes into usable output signals. The sensor’s internal electronics ensure that these outputs are accurate, stable, and compatible with industrial monitoring and control systems.

Available Output Types

Soway’s RF Admittance Level Sensors provide multiple standard output options to meet different application needs:

Analog Voltage: 0.5–4.5 V DC

Analog Current: 4–20 mA

Digital Communication: RS485 Modbus

These outputs allow the sensor to integrate seamlessly with PLCs, data acquisition systems, and process control equipment.

Calibration and Adjustment

The sensor includes an on-site calibratable function. Users can perform range setting, zero-point, and full-scale calibration directly via buttons on the sensor, ensuring reliable measurements for various liquid types, including water, oils, viscous liquids, and chemical solutions.

Advantages of Soway’s Electronics Integration

Reliable Output: Internal electronics convert admittance changes into standard analog or digital signals.

Flexible Integration: Supports multiple output types suitable for diverse industrial systems.

On-site Calibration: Easy calibration allows for precise and repeatable measurements.

Stable Performance: Ensures consistent readings across different liquid types and operating conditions.
