FEEJOY RF Admittance Level Switch measures the medium through high-frequency wireless waves, which is a more advanced RF admittance technology to exchange capacitance measurement. The RF type level switch consists of three parts of RF admittance level sensor: Measuring probe, Shield and Ground terminal. Our FRFS series RF level switch is widely used in the alarm and control of liquid, slurry, material level and two liquid interface levels. Compared with other similar RF admittance level switch products, RF level transmitter and switch have higher system stability and may work reliably even under extremely harsh field conditions. And the RF type level switch is not suffering from the hanging material, temperature, pressure, density, humidity, and even the chemical properties of the fabric.

Features of RF Admittance Level Switch

  • The RF admittance type level switch can measure the liquid level and material level, and the level switch admittance type can meet the measurement requirements of different temperatures, pressures, and media.

  • It is not affected by the RF admittance level sensor hanging material and does not need to be cleaned regularly to avoid the wrong measurements.

  • There are no moving parts in the measurement process of the RF admittance type level sensors, and there is no problem with damage to mechanical parts.

  • No maintenance, intelligent adjustment-free of RF admittance level switch for liquids.

  • Contact measurement, strong anti-interference ability, can overcome the influence of steam, foam, and stirring on the measurement of RF admittance point level switches.

  • RF admittance level measurement quantity is diversified, which makes the measurement more accurate, the measurement is not affected by environmental changes, and the stability is high.

  • Reliable product performance and long service life of RF admittance level sensors.

FEEJOY can supply OEM service for RF admittance level switch among all level switches manufacturers, which include material, working pressure, output, etc.

Application of RF Admittance Level Switch

  • Conductive and insulating liquids: Chemical industry, oil field, water and sewage treatment

  • Conductive and insulating paste: Paper, pharmaceutical, water and sewage treatment

  • RF admittance level sensor powder: Ash, powder, Power plant, metallurgy, cement

  • Particles: coal, grain power, plant, metallurgy, grain

  • Interface: two different liquids, oil field, chemical industry

The RF admittance level switch is the RF admittance level meter, and the potentiometer W1 of the radio frequency admittance level meter is a sensitivity adjustment potentiometer: the LED two-color display lamp lights in green when there is no material, and the red light when there is one. After the meter is powered on, the green light is on when the level is lower than the set value. 

At this time, slowly adjust the potentiometer W1 clockwise until the red light is on, and then adjust it 3 times counterclockwise (0.5 to 3 times for non-conductive materials, conductive material 5 ~ 7 circles) and the green light is on (the status of the output relay's contacts should change with the change of the traffic light display state). According to the measurement part of different RF admittance level transmitters, it should be covered by materials at about 75mm.

RF Admittance Level Switch FAQs

What is RF admittance level switch?

RF admittance level switch compared to capacitance level switch adopts more advanced RF admittance technology instead of capacitance measurement, which solves the problem of material adhesion.

Why choose RF admittance level switch?

Compared with other similar products, this admittance point level switch has higher stability of the system, and even in extreme conditions it also can work reliably at the scene.
