RF Admittance Level Sensor Switches

The RF level switch operates on the basis of RF absorption measurement. The electronic unit generates a sinusoidal wave, applied to the electrode creating a field around it. RF environment absorption changes (electrical loss) around the electrode are reflected on changes of generator supply current. Such changes, caused by the increase in level is amplified and used to energies the relay. The main drawback of the conventional method is that after the level has once increased and then decreased, there may be a coating left on the probe which is sensed by the instrument as though the level is still on the probe.

In JAYCEEADMIT a COAT GUARD and Trance-Conductance amplifier are incorporated in the circuit having its output exactly at the same voltage and phase at all times as its input. The output is connected through the shield of the low capacitance co-axial cable to the concentric tube on the sense probe, called shield element. Since both the elements, sense and shield are exactly at the same potential and phase at all times, there is no current flow through the cable. Thus there is no change in calibration due to coating on the probe and the temperature effect of the cable.

RF admittance level sensor switches are advanced devices used for accurate and reliable level monitoring in tanks, silos, and other containers. These switches utilize the principle of radio frequency (RF) admittance to measure the level of liquids, solids, and slurries. With their high sensitivity and versatility, RF admittance level sensor switches are widely employed in various industries for precise level control.

Working Principle:

1. The RF admittance level sensor switch operates based on the difference in electrical conductivity between the material being measured and the surrounding medium (usually air). It consists of a probe or rod inserted into the container and a control unit.

2. When the probe is inserted into the material, an RF signal is applied between the probe and the vessel wall or ground. The material's electrical properties, such as its dielectric constant and conductivity, affect the amount of current flowing between the probe and the vessel. This variation in electrical conductivity is used to determine the level of the material.

3. The control unit continuously monitors the electrical properties and calculates the admittance value. When the admittance value exceeds a preset threshold, it triggers the switching mechanism to indicate the presence or absence of the material at the desired level.


RF admittance level sensor switches are utilized in a wide range of industries and applications where precise level monitoring is crucial. Some common applications include:

Liquid Storage and Processing: These switches are extensively used in industries such as chemical, pharmaceutical, food and beverage, and water treatment. They provide accurate level measurement for inventory management, process control, and preventing overflow or dry running of pumps.

Bulk Solids Monitoring: RF admittance level sensor switches are highly effective in measuring the level of bulk solids, such as powders, granules, and grains. They ensure efficient material handling, prevent bin overflows, and control inventory levels in industries like mining, agriculture, plastics, and construction.

Silos and Hoppers: Silos and hoppers often require precise level monitoring to ensure consistent material supply and prevent blockages or overflow. RF admittance level sensor switches offer reliable measurement and can activate alarms or control mechanisms to optimize material flow.

Liquids with Varying Conductivity: These switches are suitable for liquids with varying conductivity or dielectric constants, such as oils, slurries, and emulsions. They can provide accurate level measurement even in challenging conditions, ensuring proper process control and preventing costly errors.


1. RF admittance level sensor switches offer several benefits that make them a preferred choice for level monitoring:

2. Accuracy and Sensitivity: These switches provide highly accurate level measurements, even in applications where other technologies may struggle. They offer excellent sensitivity, enabling precise control of levels, especially in challenging materials.
